Class 9 Science Chapter 12 Study of Sound Question Answer Maharashtra Board

1. Fill in the blanks and explain.

a. Sound does not travel through ……………………….……….. .
b The velocity of sound in steel is ……………………….………… than the velocity of sand in water.
c. The incidence of ……………………….………… in daily life shows that the velocity of sound is less than the velocity of light.
d. To discover a sunken ship or objects deep inside the sea, ……………………….………… technology is used.

2. Explain giving scientific reasons.

a. The roof of a movie theatre and a conference hall is curved.
Answer:

Sound waves get reflected from the walls and roof of a room multiple times. This causes a single sound to be heard not once but continuously. This is called reverberation.
Due to reverberation, some auditoriums or some particular seats in an auditorium have inferior sound reception. This can be compensated with curtains.
Ceilings of these halls are made curved so that sound after reflecting from the ceiling, reaches all parts of the hall and the quality of sound improves.

b. The intensity of reverberation is higher in a closed and empty house.
Answer:

Reverberation occurs due to multiple reflections of sound.
The furniture in the house acts as a sound-absorbing material.
So if the house is closed and empty, a reflection of sound will be maximum and hence, intensity of reverberation is higher.

c. We cannot hear the echo produced in a classroom.
Answer:

For distinct echoes, the minimum distance of the reflecting surface from the source of sound must be 17.2 m.
Benches in the classroom are sound absorbing materials which prevent echo of sound.
Because of these two reasons echo is not heard in a classroom.

3. Answer the following questions in your own words.

a. What is an echo? What factors are important to get a distinct echo?
Answer:

An echo is the repetition of the original sound because of reflection by some surface.
At 22°C, the velocity of sound in air is 344 m/s.
Our brain retains a sound for 0.1 seconds Thus, for us to be able to hear a distinct echo, the sound should take more than 0.1 seconds after starting from the source to get reflected and. come back to us.
We know that,
Distance = speed x time
= 344 m/s x 0.1 s
= 34.4 m
Thus, to be able to hear a distinct echo, the reflecting surface should be at a minimum distance of half of the above, i.e. 17.2 m.
As the velocity of sound depends on the temperature of air, this distance depends on the temperature.

b. Study the construction of the Golghumat at Vijapur and discuss the reasons for the multiple echoes produced there.
Answer:

Goighumat with a height of 51 metres and diameter of 37 metres with 3 metres thick walls is spread over approximately 1700 square metres.
This meets the conditions for echo i.e. : 17.2 metres minimum.
The dome of the golghumat is curved and hence, sound reflects multiple times before reaching the observer.
This is the reason for multiple echoes being produced.

c. What should be the dimensions and the shape of classrooms so that no echo can be produced there?
Answer:

Dimensions: The distance between opposite walls in a classroom must be less than 17.2 m so that the reflected sound returns to the observer within 0.1 s.
Shape: The classrooms should have curved ceilings and walls so that the reflected sound is directed towards the observer instantly within 0.1 s

4. Where and why are sound-absorbing materials used?
Answer:
The sound absorbing materials are used in :

School, cinema hall, concert hall, houses or places where quality of sound is important.
In the absence of sound absorbing material the sound will undergo multiple reflection causing reverberation of sound.

5. Solve the following examples.

a. The speed of sound in air at O °C is 332 m/s. If it increases at the rate of 0.6 m/s per degree, what will be the temperature when the velocity has increased to 344 m/s?
Answer:
Given:
Initial speed of sound at 0°C 332 m/s.
Final speed of sound -344 m/s.
Rate of increase per degree rise in temp. = 0.6m/s
To find:

b. Nita heard the sound of lightning after 4 seconds of seeing it. What was the distance of the lightning from her? (The velocity of sound in air is 340 m/s?)
Answer:
Given : Speed of sound (v) = 340 m/s
Time taken (f) = 4 sec
To find : Distance (s) = ?

The lightning has struck at a distance of 1360 m from the observer.

c. Sunil is standing between two walls. The wall closest to him is at a distance of 360 m. If he shouts, he hears the first echo after 4 s and another after another 2 seconds.
1. What is the velocity of sound in air?
2. What is the distance between the two walls? (Ans: 330 m/s; 1650 m)
Answer:
Given:
Distance of the closer wall (S₁) = 660 m
Time of echo from closer wall = 4 sec
∴ Time taken (t₁) = 4/2 sec = 2 sec
Time of echo from distant wall = 6 sec
∴ Time taken (t₂) = 6/2 sec = 3 sec
To find :
Velocity of sound in air (y) =?
Distance between two walls (S₁ + S₂) = ?

The velocity of sound in air is 330 mIs and the distance between two walls is 1650 m.

d. Hydrogen gas is filled in two identical bottles, A and B, at the same temperature. The mass of hydrogen in the two bottles is 12 gm and 48 gm respectively. In which bottle will sound travel faster? How may times as fast as the other? (Ans: In A; Twice)
Answer:
In A; Thrice

e. Helium gas is filled in two identical bottles A and B. The mass of the gas in the two bottles is 10 gm and 40 gm respectively. If the speed of sound is the same in both bottles, what conclusions will you draw? (Ans: Temperature of B is 4 times the temperature of A.)
Given:
Mass of Helium in bottle A = (mA) = 10gm
Mass of Helium in bottle B = (mB) = 40gm

The temperature of B is 4 times the temperature of A

9th Science Chapter 12 Study Of Sound Exercise Question 3.
To hear the echo distinctly, will the distance from the source of sound to the reflecting surface be same at all temperatures? Explain your answer.
Answer:

No,the distance from the source of sound to the reflecting surface will not be the same at all temperatures.
Velocity of sound is directly proportional to the square root of temperature.
One of the conditions of echo is that the time interval between the original and reflected sound should be more than 0.1 sec.
So if the temperature increases, the velocity of sound increases and the reflected sound reaches in less than 0.1 sec.
So for echo to be heard the distance between the observer and the reflecting surface has to increase.

Answer in detail:

Question 1.
What are the factors on which velocity of sound in gaseous medium depend?
Answer:
The velocity of sound in a gaseous medium depends on the physical conditions i.e. the temperature, density of the gas and its molecular weight.

Temperature (T): The velocity of sound is directly proportional to the square root of the temperature of the medium. This means that increasing the temperature four times doubles the velocity.
\(\text { v } \alpha \sqrt{\mathrm{T}}\)
Density(p): The velocity of sound is inversely proportional to the square root of density. Thus, increasing the density four times, reduces the velocity to half its value.
\(\mathrm{v} \alpha \frac{1}{\sqrt{\rho}}\)
Molecular weight (M): The velocity sound is inversely proportional to the square root of molecular weight of the gas. Thus, increasing the molecular weight four times, reduces the velocity to haff its value.
\(\mathrm{v} \alpha \frac{1}{\sqrt{\mathrm{M}}}\)

Question 2.

Answer:
Uses of ultrasonic sound are as follows:

For communication between ships at sea.
To join plastic surfaces together.
To sterilize liquids like milk by killing the bacteria in it so that the milk keeps for a longer duration.
Echocardiography which studies heartbeats, is based on ultrasonic waves (Sonography technology).
To obtain images of internal organs in a human body.
In industry to clean intricate parts of machines where hands cannot reach.
To locate the cracks and faults in metal blocks.

Question 3.
Explain with the help of a neat labelled diagram the working of human ear.
Answer:

The ear is an important organ of the human body.
When sound waves fall on the eardrum, it vibrates and these vibrations are converted into electrical signals which travel to the brain through nerves.
The ear can be divided into three parts:
(a) Outer ear
(b) Middle ear
(c) Inner ear.

(a) Outer ear or Pinna
The outer ear collects the sound waves and passes them through a tube to a cavity in the middle ear. Its peculiar funnel like shape helps to collect and pass sounds into the middle ear.

(b) Middle ear
There’ is a thin membrane in the cavity of the middle ear called the eardrum. When a compression in a sound wave reaches the eardrum, the pressure outside it increases and it gets pushed inwards. The opposite happens when a rarefaction reaches there. The pressure outside decreases and the membrane gets pulled outwards. Thus, sound waves cause vibrations of the membrane.

(c) Inner ear
The auditory nerve connects the inner ear to the brain. The inner ear has a structure resembling the shell of a snail. It is called the cochlea. The cochlea receives the vibrations coming from the membrane and converts them into electrical signals which are sent to the brain through the nerve. The brain analyses these signals.

Question 4.
Write a short note on SONAR
Answer:

(i) SONAR is the short form for Sound Navigation and Ranging. It is used to determine the direction, distance and speed of an underwater object with the help of ultrasonic sound waves. SONAR has a transmitter and a receiver, which are fitted on ships or boats.

(ii) The transmitter produces and transmits ultrasonic sound waves. These waves travel through water, strike underwater objects and get reflected by them. The reflected waves are received by the receiver on the ship.

(iii) The receiver converts the ultrasonic sound into electrical signals and these signals are properly interpreted. The time difference between transmission and reception is noted. This time and the velocity of sound in water give the distance from the ship, of the object which reflects the waves.

(iv) SONAR is used to determine the depth of the sea. SONAR is also used to search underwater hills, valleys, submarines, icebergs, sunken ships etc.

Question 5.
Write a short note on Sonography. How is it misused?
Answer:

Sonography technology uses ultrasonic sound waves to generate images of internal organs of the human body.
This is useful in finding out the cause of swelling, infection, pain, condition of the heart, the state of the heart after a heart attack as well as the growth of foetus inside the womb of a pregnant woman.
This technique makes use of a probe and a gel.
The gel is used to make proper contact between the skin and the probe so that the full capacity of the ultrasound can be utilized.
High-frequency ultrasound is transmitted inside the body with the help of the probe.
The sound reflected from the internal organ is again collected by the probe and fed to a computer which generates the images of the internal organ.
As this method is painless, it is increasingly used in medical practice for correct diagnosis.
This technique is used by many people to find out gender of an unborn baby and this often leads to the incidence of female foeticide.

Marketing involves price of a commodity, its sales promotion, its advertising and its proper distribution.

In the traditional marketing system, the farmers used to sell their products in the local market at whatever price available. This is because the fruits and vegetables are perishable, so the farmers used to incur losses,
However, the modem farmers have acquired skills in marketing. They are aware of the trends in the market.
They produce food grains and fruits as per the international standards.
They undertake grading and packaging of their products. The presentation of any product has become indispensable now.
They advertise the quality of their product and keep the same for sale, along with samples, in the mall.
These commercial-minded farmers contact the supermarkets and exporters through the internet.
As a result, their products are sold at a higher price in the malls. They also fetch a good price from exports.
Thus marketing is as important as the cultivation of crops. By following modem marketing techniques, the income of the farmers can increase and that can improve their standard of living.

Distributional Maps Class 9 Questions And Answers Maharashtra Board

Class 9 Geography Chapter 1 Distributional Maps Questions And Answers Maharashtra Board

Geography Class 9 Chapter 1 Question Answer Maharashtra Board

1. Give reasons why the following sentences are right or wrong:

Geography Class 9 Chapter 1 Distributional Maps Question 1.
The main aim of distributional maps is to show location.
Answer:
Wrong The main aim of distributional maps is to show the distribution of variables like temperature, rainfall, population, etc.

Distribution maps are type of thematic maps.
These maps are prepared with special themes like the distribution of various variables in a particular region.
They make use of different methods to show the distribution of variables like temperature, rainfall, population, etc.

Thus, the main aim of distributional maps is to show the distribution of variables in a particular region.

Distributional Maps Class 9 Question 2.
In choropleth maps, only one value is assigned to the sub-administrative unit.
Answer:
Right

In choropleth maps, the data regarding various geographical variables is shown by shading or using tints of various colours.
After gathering the data for a selected variable, five to seven classes are made considering the smallest and the largest values.
Each class is assigned a tint of the same colour or black-and-white patterns.
A particular value shown by a predecided tint of colour can represent only a particular region or group of region.

Thus, in choropleth maps, only one value is assigned to sub administrative unit.

Distributional Maps Questions And Answers Question 3.
In choropleth maps, colours/tints do not change according to the values of the variables.
Answer:
Wrong.
In choropleth maps, colours/tints change according to the values of variables.

In choropleth maps, the smallest and the largest values are taken into consideration and after that 5-7 classes are made.
Each class is assigned a unique tint of the same colour or black and white pattern.
In other words, each class is used to show the distribution of a particular variable in sub- administrative unit.

Distributional Map Question 4.
Choropleth maps are used to show altitudes.
Answer:
Wrong.
Isopleth maps and not the choropleth maps are used to show altitude.

When the distribution of a variable is continuous like the altitude, the isopleth method map is used.
Isopleth maps use lines joining the locations having equal values and hence are useful to show the change in altitude in the region.
When the distribution of a variable is discontinuous, the choropleth method map is used to show its distribution, eg. distribution of population, domestic animals, etc.

Question 5.
Isopleth maps are used to show population distribution.
Answer:
Wrong.
Dot method maps or choropleth method maps are used to show population distribution

Distribution of a population is discontinuous.
Isopleth method maps are used to show the distribution of variables which are continuous. For eg. altitude, temperature etc.
Thus, isopleth method maps are not used to show population distribution.

Question 6.
In dot method, every dot should have an appropriate scale.
Answer:
Right.
The size of the dot is decided as per the value of a variable that is freely scattered across the region.

Question 7.
Isopleth maps are not made using isolines.
Answer:
Wrong.
Isopleth maps are made using isolines.

Isolines are lines joining places of same values of a given variable in a map.
Since, isopleth maps are also prepared in the same method, we can say that they are made using isolines.

Question 8.
Distribution of various geographical elements can be shown using dot method.
Answer:
Wrong.
Distribution of various geographical elements cannot be shown using dot method.

Distribution of geographical elements which are freely scattered across a region can be shown using a dot method.
Distribution of variables like population, minerals, cattles etc., are freely scattered hence can be shown on a dot method map.
Whereas the distribution of variables like rainfall, altitude, temperature etc. which are continuous, cannot be shown using a dot method map.

2. Answer in brief.

Question 1.
Explain the use and types of distributional maps.
Answer:
(a) Use of distributional maps: The distributional maps are useful for explaining the patterns of distribution of a particular geographical variable.
(b) The types of distributional maps : The following are the types of distributional maps.

Dot Method: The distributional map based on statistical data, made by this method, make use of dots of a pre-decided size to show the distribution of a particular variable, e.g. Dot method map is used to show the population of a region, distribution of cattle etc.
Choropleth Method: The distributional map made by this method makes use of shades or tints of various colours, to show the distribution of a particular variable, e.g. Choropleth method map is used to show population density, types of forest cover, uses of land.
Isopleth Method: The distributional map made by this method makes use of lines joining locations or places having same or equal values of a particular variable, e.g. Isopleth method map is used to show altitude, temperature, rainfall.

Question 2.
Differentiate between choropleth and isopleths methods.
Answer:

Choropleth Method	Isopleth Method
(1) In Choropleth method maps, the distribution of various variables are shown by shading or using tints of the same colour.	(1) In Isopleth method maps, the distribution of various variables are shown with the help of isolines.
(2) When the distribution of a variable is not continuous, the choropleth method is used.	(2) When the distribution of a variable is continuous, the isopleth method is used.
(3) Choropleth method is used to show population density, cattle distribution etc.	(3) Isopleth method are used to show altitude, temperature, rainfall of a region etc.

Question 3.
Explain with reasons the method which is best suited to show the distribution of population in a region.
Answer:

The dot method of making a distributional map is best suited to show the distribution of the population in a region.
The dots used in this method, are given a particular value which is determined by selecting a proper scale considering the spread of the values of the variables in the given region.
This method is best suited to show the distribution of the variables which are freely scattered as in the case of population distribution.

5. Answer in brief:

Question 1.
In what ways does precipitation occur on the earth?
Answer:
Precipitation means water falls in the solid or liquid state from the clouds to the earth surface. Snow, hailstorms, rainfall are the major forms of precipitation.

(i) Snow:
Answer:

When the temperature in the atmosphere falls below the freezing point the water vapour directly turns into snowflakes. This is called sublimation.
Hence the vapour in the form of gas transform into solid snow. Precipitation in the form of solid particles is known as snowfall.
As snow is in the solid form. It does not run like water and layers of the snow get deposited on the top of the others and when the snow melts the region gets fresh water.

(ii) Hail:

When there is lot of heat on the earth’s surface, the upward air flow blows at a greater speed. Because of this upward flow, the temperature of air reduces and the condensation of the water vapour takes place, and dark clouds are formed.
Because of the upward movement of the air, these water droplets go at higher altitude and solidify forming hailstones.
As the hailstones are heavy, they fall toward the earth’s surface because of gravity. The crops may get destroyed and loss of life and property may occur.
Hailstones occurs in summer in India, Africa and in some parts of south east Asia.

(iii) Rainfall:

We get water generally in the form of rainfall. The temperature of the air with water vapour reduces when it goes higher and condensation of the vapour occurs.
Clouds formed with the condensed water droplets and dust particles accumulate.
As these water droplets increase in the size, they cannot float in the air anymore because of their weight. They come down as rainfall
The different types of rainfall are: Convectional rainfall, Orographic rainfall and Cyclonic rainfall.

(iv) Fog, dew and frost:

When the condensation or solidification of the water vapour in the atmosphere occurs near the earth’s surface, it leads to the formation of fog, dew and frost.

Question 2.
Comment on the rainfall occurring in the rain shadow area.
Answer:

The winds coming from lakes or seas are moisture-laden and they are obstructed by the high mountain ranges coming in their way
They start going upwards along the slope of the moutains. The temperature of these winds drop and condensation occurs and rainfall takes place.
This rainfall takes place because of the obstruction of the mountains which results in the condensation of water vapour.
The windward side of the mountain gets more rain; the amount of vapour in the air reduces after crossing the mountain and the moisture-holding capacity of the air increases.
The leeward side of the mountain gets lesser rainfall as compared to windward side.
Thus, the leeward side area is identified as rain shadow area as it recieves meagre rainfall.

Question 3.
Which type of rainfall occurs in most of the world? Why?
Answer:

Orographic rainfall occurs in most parts of the world.
Convectional rainfall is regional in nature.
There is a certainty in the convectional rainfall occurring in the equatorial areas.
Comparatively, the orographic and cyclonic rainfall is less certain.
And therefore, such areas are prone to very heavy rainfall, floods or droughts frequently.

Question 4.
If condensation occurs closer to the earth’s surface, what types of forms become visible?
Answer:
If condensation and solidification of the water vapour in the atmosphere closer to the earth surface are visible, they are in the form of fog, dew or frost.

(i) Fog:

The temperature of the layers of the air near the surface of the earth reduces. As the temperature reduces, water vapour condenses.
In this process the water vapour turns into microscopic water particles and float in the air.
When the density of these droplets in the air increases it leads to the formation of fog

(ii) Dew:

When moisture-laden air near the earth surface comes in contact with very cold objects condensation of water vapour takes place.
They turn into very small water droplets and stick to the surface of cold objects, e.g. eg: leaves and this is called dew.

(iii) Frost:

When the temperature of the air reaches less then 0 degree Celcius the water droplet stuck to the surface of the cold objects and freezes.
This frozen water droplet is called as frost.

Question 5.
What precautions should be taken while measuring rainfall?
Answer:

Rainfall is an important source of water on planet earth and rainfall is formed because of changes in the temperature of the air with water vapour.
The instrument that is used to measure rainfall is called rain gauge.
The funnel i.e. used for measuring rain has a specific diameter and the rain falling in this funnel is collected in bottle fitted in the gauge.
The collected water is then measured with the help of measuring jar. In the areas of heavy rainfall, the reading of the rain with rain gauge should be taken every three hours. The measuring jar reads rain in millimetres
The gauge has to be kept on open ground on 30cm high flat-mount.
So that the rain water is collected without any obstruction.

Class 9 Geography Chapter 5 Precipitation Intext Questions and Answers

Can you tell?

Question 1.
The blade of grass look like this in winter mornings. From where does the water on the blades of grass come?
Maharashtra Board Class 9 Geography Solutions Chapter 5 Precipitation 8
Answer:

The blade of grass looks like this in winter mornings because of dew. These are small water droplets.
The dew is formed in winter because moisture-laden air near the earth surface comes in contact with cold objects due to which condensation of vapour takes place, turning into small water droplets.

Question 2.
Snow is found everywhere in the winters in Kashmir.
Answer:
Snow is found everywhere in winters of Kashmir because Kashmir is located at a higher altitude where the temperature falls below freezing point. Hence water vapour directly turn into snowflakes leading to snowfall.

Question 3.
Why isn’t snow found in our surroundings?
Answer:
Because we have a moderate temperature and we are closer to the sea, snow is not found in our surroundings.

Question 4.
Generally, it rains between June and September in our region.
Answer:
We get rainfall between June and September, in our region when the moisture-laden south-west monsoon winds are obstructed by the Western Ghats leading to orographic rainfall.

Question 5.
How do the rain droplets form?
Answer:
Clouds form when condensed water droplets and dust particles accumulate forming large rain droplets.

Question 6.
In London, there is a fog like this till the afternoon in the winters.
Answer:
In London there is fog till the afternoon in winters because London is far away from equator and it has temperate oceanic climate and they have cool summers.

Question 7.
We do not have fog until afternoons in summers.
Answer:
We do not have fog until afternoons in summer because we are near to equator and we have tropical climate and hot summers.

Question 8.
Sometimes hailstones destroy the standing crops in the field.
Answer:
Hailstones are solid and heavy in nature and they hit the earth due to gravity and this is the reason they destroy the crops in the field.

Question 9.
Why don’t we get hailstones frequently?
Answer:
For the formation of hailstones the following 2 conditions are required:

Intense heating which results in upwards air flow.
The decrease in air temperature at higher layers of the atmosphere.
As India is a tropical country, we do not find cooler air at higher levels because of the intense heating of land.

Think about it.

Question 1.
We use a raincoat or umbrella to protect ourselves from rainfall. What will you use to protect yourself from severe hailstorms?
Answer:
If a person is outside without any coverage, he needs to seek shelter immediately, making sure to protect his head from hailstones.

Question 2.
Because of the conventional processes, convectional rainfall occurs in the afternoon in equational areas. But why doesn’t it rain in afternoons in the oceanic areas of the equatorial belt?
Answer:
One of the necessary conditions of convectional rainfall is intense heating of surface which causes air to expand and rise. Since land heats up faster than water, it rains only on the land in the equatorial regions and not in the oceanic areas.

Question 3.
Why are the areas of high rainfall situated in tropical areas?
Answer:

Tropical areas receive direct rays of the Sun almost throughout the year. Hence the rate of evaporation1 is high here.
The tropical region receives convectional rainfall throughout the year and also orographic rainfall is experienced here.
Thus areas of high rainfall are situated in the tropical area.

Maharashtra Board Class 9 Geography Solutions Chapter 5 Precipitation 3
Question 1.
Which region experiences more rainfall?
Answer:
The tropical region experiences more rainfall.

Question 2.
What is the reason for low rainfall in the Central Peninsular India?
Answer:
The Central Peninsular India falls on the leeward side of the Western Ghats and hence a rain shadow region is formed here.

Question 3.
Why does the eastern part of Central African continent gets less rainfall than the western part despite its location close to the equator?
Answer:

Eastern part of the African Continent is a rain shadow region of westerly monsoon winds whereas the western part lies on the windward side and gets more rain.
The eastern part of Africa also comes under the influence of the North east trade winds but still receive less rains as they are dry winds originating from the land.

Question 4.
Why does the amount of high rainfall in the western part of the European continent reduce in the eastern part?
Answer:
There are many mountain ranges in the western part of Europe. These obstruct the rain-bearing clouds coming from the west and therefore the amount of rainfall received is high in the west and it reduces towards the east.

Question 5.
Why is rainfall more only in the eastern coast of Australia?
Answer:
The eastern part of Australia is a mountainous region. The winds blowing from the Pacific Ocean are obstructed by these mountains resulting in orographic rainfall towards the east and the formation of a rain shadow zone towards the west.

Maharashtra Board Class 9 Geography Solutions Chapter 5 Precipitation 4
Question 1.
What type of rainfall occurs in Maharashtra?
Answer:
Orographic rainfall occurs in Maharashtra.

Question 2.
Where will the rain shadow area lie in Maharashtra?
Answer:
The rain shadow area lies to the Leeward side of Sahyadri hills (Maharashtra plateau).

Question 3.
Think about the figure and estimate the rainfall of your district.
Answer:
The answer may vary.

Give reasons:

Question 1.
Crops may get destroyed due to hailstones.
Answer:

As hailstones are heavy they fall towards the earth’s surface, but because of the frequent upward flow of air, they are repeatedly taken upwards.
Here, a new layer of snow encapsulates the hail. This happens quite a few times.
Hence, concentric layers are formed while the hail grows in size.
These big heavy hailstones fall rapidly to the ground because of gravity. This type of precipitation is called as hail.
Hence due to hail, crops may get destroyed.

Question 2.
There is a difference between ice and snow.
Answer:

In areas located at higher altitudes and high- latitudes, where the temperatures are below 0°C get precipitation in the form of snow.
Snow is friable and opaque. This snow accumulates in the form of layers on top of each other.
Because of the pressure from the upper layers, the lower layers of the snow become homogeneous, massive and transparent.
Massive transparent snow formed in such a way is called ice.

Thus, there is a difference between ice and snow.

Question 3.
In equatorial areas, convectional rainfall occurs almost daily in the afternoons.
Answer:

In equatorial areas, the surface gets heated because of the sun’s heat and the air near it also gets heated.
As it gets heated, it spreads and becomes lighter and moves upwards. It cools down when it goes upward. The moisture-holding capacity of cold air is less.
Consequently, condensation of the water vapour occurs and rainfall occurs in equatorial areas.
Thus in equatorial areas, convectional rainfall occurs almost daily in the afternoons.

Question 4.
A rain shadow area is formed on the leeward side of the Western Ghats.
Answer:

Winds coming from Arabian sea are moisture-laden. They are obstructed by the Western Ghats coming in their way.
According to the slope of the Western Ghats, the moisture-laden winds start going upwards.
The temperature of these winds drop and condensation occurs and rainfall takes place. Thus, because of the obstruction of the Western Ghats, orographic rainfall occurs.
The windward side of the mountains gets more rain; amount of vapour in the air reduces after crossing the mountain and the water vapour carrying capacity of the air increases.
The leeward side of the mountain gets lesser rainfall and hence a rain-shadow area is formed here.

Question 5.
Snowfall is not experienced in Maharashtra.
Answer:

Solid snow particles are formed in regions where the temperature falls below the freezing point leading to the process of sublimation.
In the sublimation process, the water vapour directly turns into snowflakes.
In Maharashtra, during winters the temperature never falls below the freezing point.
Hence snowflakes are never formed in the atmosphere.
Thus snowfall is not experienced in Maharashtra.

Question 6.
Hailstones do not occur frequently.
Answer:

Strong vertical movements of air with very high difference in temperature are an ideal condition for the formation of hailstones.
Presence of moisture is also necessary in the air.
Such conditions do not exist frequently.
Hence hailstones are not experienced frequently.

Question 7.
Dew and frost occur on a large scale in winters.
Answer:

During winters when moisture-laden air near the earth’s surface comes in contact very cold objects, condensation of the vapour takes place.
They turn into very small water droplets. These water droplets get stick to the surface of the cold objects. This is called dew.
If the temperature of the air is less than 0°C, the water droplets stuck to the surfaces of cold objects freeze.
This frozen water droplet is called frost.
Thus dew and frost occur on a large scale in winters.

Question 6.
Explain the effects of precipitation.
Answer:

The main source of potable water available on the earth is precipitation.
As extreme rainfall is destructive so is the absence of rainfall.
Floods may occur because of heavy rainfall and causes loss to life and property.
If precipitation does not take place then conditions of drought arise. It causes a shortage of food and food may have to be imported and farmers’ conditions becomes grave.
The economy of an agrarian1 country like India is dependent on agriculture. The agriculture in India to a large extent is dependent on monsoons. Hence rainfall in India is important to the whole country.
A good rainfall at the right time increases crop production while untimely rain can damage the crope.
Acid rains which is a combination of harmful gases and rainwater is harmful to the living organisms as well as non-living objects.

Explain:

Question 1.
Snowfall
Answer:

When the temperature in the atmosphere falls below the freezing point, the water vapour directly turns into snowflakes. This is called sublimation.
Here, the vapour in the form of gas transforms into solid snow.
Precipitation in the form of solid particles is known as snowfall.
In high latitudinal and temperate regions, snowfall occurs at the mean sea level while in tropical areas, snowfall occurs at places located higher than the snowline altitude.

Question 2.
Formation of hailstones.
Answer:

When there is a lot of heat on the earth’s surface, the upward air flow blows at a great speed.
Because of this upward flow, the temperature of the air reduces and the condensation of the water vapour takes place.
Dark clouds are formed. Because of the upward movement of air, these water droplets go at a higher altitude.
Here, solidification of these droplets occur and hailstones are formed.

Question 3.
Cyclonic rainfall
Answer:

Cyclone is the specific air formation when the pressure at an area is less than the surrounding regions.
Air from the surrounding region comes toward the center of the cyclone and starts moving upwards.
As it rises, the temperature of the air reduces, condensation occurs and rainfall takes place.
It rains in areas over which the cyclone passes. Cyclonic rainfall occurs more in temperate zones and its area is also quite extensive.
Comparatively, cyclonic rainfall occurring in tropical regions is limited in extent and is stormy in nature.

Question 4.
Rain Gauge.
Answer:

The instrument that is used to measure rainfall is called rain gauge.
The funnel that is used for measuring rain has a specific diameter. The rain falling in this funnel is collected in a bottle fitted in the gauge.
The collected water is then measured with the help of measuring jar. The measuring jar reads in millimetres.
In areas of heavy rainfall, the reading of the rain is taken every three hours.
The gauge is kept on open ground on a 30cm flat-mount. Hence, the rainwater is collected without any obstruction.

Question 5
Fog, dew and frost
Answer:
(i) Fog:

The temperature of the layers of the air near the surface of the earth reduces. As temperature reduces, water vapour condenses.
In this process, vapour turns into microscopic water particles and float in the air.
When the density of these droplets in the air increases, fog occurs.

(ii) Dew:

When moisture-laden air near the earth’s surface comes in contact with very cold objects, condensation of the vapour takes place. They turn into very small water droplets.
These water droplets get stick to the surface of the cold objects. This is called dew.

(iii) Frost:

If the temperature of the air reaches less than 0°C, the water droplets stuck to the surfaces of cold objects and freeze.
This frozen water droplet is called frost.

Question 6.
Acid Rain
Answer:

Because of air pollution in industrial areas, various gases get mixed in the air.
Different adds are created when the water vapour in the air reacts chemically with these gases. For example, nitric add, sulphuric add, etc.
Acids dissolved in rainwater fall with the rain j during precipitation. Such a type of rain which has acids dissolved in it is called acid rain.
Such type of rainfall is harmful to the living organisms and the non-living objects.

Question 7.
Convectional Rainfall
Answer:

In equatorial areas, the surface gets heated because of the sun’s heat and the air near it also gets heated. As it gets heated, it spreads and becomes lighter and moves upwards.
It cools down when it goes upward & as the j moisture-holding capacity of cold air is less, condensation and rainfall occurs.
This type of rainfall is called as Convectional! Rainfall.
In equatorial areas, such a type of rainfall occurs almost daily in the afternoons. Rainfall is accompanied by lightning and thunder.
The Congo basin of the Africa and the Amazon basin in the South America experience convectional rainfall.
Such a rainfall has a very limited area on the earth.

Question 8.
Orographic rainfall
Answer:

Winds coming from lakes or seas are moisture-laden. They are obstructed by the high mountain ranges coming in their way.
They start going upwards along the slope of the mountains.
The temperature of these winds drop and condensation occurs and rainfall takes place. Thus because of the obstruction of the mountains, this type of rainfall occurs.
The windward side of the mountains gets; more rain; the amount of vapour in the air reduces after crossing the mountain and the moisture-holding capacity of the air increases.
The leeward side of the mountain gets lesser rainfall and hence this area is identified as rain- shadow area.

Answer:

Technology and mechanisation increase industrial production, creates employment and is useful for urbanisation.
In recent decades, the use of technology and mechanisation has increased in agriculture.
Due to the mechanisation of agriculture, the surplus manpower employed in agriculture have become devoid of agricultural work.
This working class started coming to cities to look for work and as a result urban population started increasing.

(B) Trade
Answer:

When a place in a region is favourable in terms of transport, loading-unloading and storage of goods, it developes into a trade centre.
This leads to the growth of business complexes, banks, credit societies, godowns, cold storage, houses, etc.
For example, Nagpur’s central location has facilitated trade and hence urbanisation has also taken place here.

Industrialisation leads to increase in the hopes of people who are attracted towards the industries from surrounding areas for employment.
Rapid growth of Mumbai in the 19th century was due to the textile mills which were started here.
Many fishing villages (Koliwadas) became part of Mumbai metropolitan2 area due to industrialisation and urbanisation.

Urbanisation leads to development of a number of amenities and facilities in urban areas.
Transportation, communication, educational facilities, medical facilities, fire brigade, various sources of entertainment, etc. are examples of amenities in urban areas.
A good transportation not only makes a journey easier but also has a positive effect on freight transport, development of markets, trade, etc.
Development of higher educational facilities in urban areas attract students from rural areas to urban areas. E.g. Pune.
Development of high quality medical facilities in urban areas bring many patients and their family members from different parts of India to these areas.

(E) Social harmony in the cities
Answer:

Social harmony refers to the exchange of cultural and social customs and traditions as people from different parts live together in the cities.
An increase in urbanisation leads to an increase in secondary, tertiary and quaternary occupation.
This results in an increase in employment opportunities due to which people from different parts of the country come to cities and there is an exchange of customs and traditions.

4. Compare the following and give examples:

(A) Transportation system and traffic jams
Answer:

As cities grow, people start living on the outskirts and in the suburbs of the city.
People commute to the centre of the city for businesses and industries, trade, jobs, education, etc.
Public transportation system is insufficient and hence the number of private vehicles increase.
This results in an increase in traffic jams and a lot of time is consumed in travelling from one place to another.
e.g. Although Mumbai has a well developed transportation system it is insufficient to fulfil the growing needs of people.

Hence, traffic jams are a frequent site in different pockets of Mumbai.

(B) Industrialisation and air pollution
Answer:

Industrialisation refers to the growth in number of industries in a particular region.
As more and more industries crop up, it becomes convenient for the industries to violate the environmental laws.
Paucity of facilities, insensitivity towards environment are the other factors which leads to an increase in the pollution level.
Hence, Industrialisation and Air pollution are the two aspects of the same coin.
e.g. Delhi, Faridabad and Varanasi are the ! victims of rapid industrialisation leading to j severe air pollution.

The increase in the number of migratory people causes an increase in the slums.
Generally migration from rural to urban areas takes place in search of job opportunities, which are hard to find.
The housing facilities do not increase in the same proportion as the population, so the poor migrants can not afford the housing in the cities.
This encourages the migrants to build illegal temporary and semi-structured houses known as slums, in open spaces. e.g. Slums in Dharavi (Mumbai city)

(D) Amenities and increasing crime
Answer:

Amenities refers to facilities that provide comfort, convenience or pleasure to people.
Transportation, communication, educational and medical facilities, fire brigade, etc. are the examples of amenities available in urban areas.
Unemployed people who have migrated to the cities are unable to avail these amenities.
This leads to an increase in thefts, burglaries, scuffles5, murders, etc. which disturb the social harmony of the cities.
e.g. Pick pocketing in the local trains.

5. Complete the table :

Process of urbanisation	Effects
Emergence of slums	Illegal settlements Insufficient facilities
	Increase in population because of attraction of good lifestyle Can be short-term or long-term
Pollution
	Employment opportunities were generated Increase in amenities and facilities
Change from rural to urban

6. Explain:

(A) The growth of cities takes place in a specific method.
Answer:
Villages are transforming into cities. The growth of cities take place in a particular pattern.

At first various industries like factories, mills, energy plants, multi-purpose projects3 etc., come up in rural areas.
People from surrounding areas come to work here and the population of the village increases.
To fulfill their needs other services develop like medical facilities, food, hospitals, recreation, etc.
The Gram Panchayat gives way to a Municipal Corporation.
These bodies provide basic services to citizens like drinking water, roads, transportation, sewerage network, street lighting etc.
Other facilities develop like town planning recreation facilities, tourist places, parks etc.

(B) A planned city of your imagination
Answer:

A city which is carefully planned from its inception and is constructed in a previously undeveloped area is a planned city.
A planned city is one in which there is adequate infrastructural facilities like roads, railways, water supply, power supply, etc.
Also, there should be open spaces available for recreation facilities.

The development and concentration of industries in a region is a factor contributing towards urbanisation.
Increase in industries leads to increase in the hopes of people who are attracted towards these industries from surrounding areas.
An increase in population leads to the development of infrastructural facilities like roadways, railways, power supply, water supply etc. which are the characteristics of a planned city.
In the 19th century, Mumbai grew rapidly because textile mills started on a large scale.

(D) Pollution- A problem
Answer:

Pollution is the introduction of contaminants into natural environment that causes adverse changes.
Pollution can be that of air, water, noise, solid waste, etc.
Pollution can adversely affect the human health.
Water pollution can lead to several water borne diseases like typhoid, cholera etc. Air pollution can lead to asthma and other respiratory diseases. Noise pollution can lead to sleep disturbance, hearing impairment etc.

(E) Swachchh Bharat Abhiyan
Answer:

Swatch Bharat Abhiyan is a cleanliness campaign run by the Government of India.
‘One step towards cleanliness’ is the objective of this campaign.
This campaign aims to keep the streets and infrastructure of the country’s cities, towns and its rural areas clean.
The funds for this programs are raised by ‘Swachchh Bharat Cess’.

Geography Class 9 Chapter 3 Question Answer Maharashtra Board

1. Answer in brief.
(a) What is mechanical weathering?
Answer:

The disintegration of rocks without any change in their chemical composition is called mechanical weathering.
The minerals in the rocks expand because of heat and contract when the temperature decreases. Due to such continuous contracting and expansion, tension develops in the rock particles.
Each mineral reacts differently to the temperature; some minerals expand more, while others do not expand as much. Consequently, the tension formed in the rocks also increases and decreases. As a result, cracks develop in the rocks and they break.
In areas where the temperatures drop below 0°C for quite some time, the water accumulated in the cracks and crevices in the rocks freezes. Its volume increases which leads to tension in the rocks and they shatter.
When the alkaline water of the sea fills in the cracks of the rocks, the soluble minerals in the rock get dissolved leading to the formation of small holes in the rocks.
Because of the heat, this water turns into water vapour and only crystals of alkaline materials remain in the rocks. Crystals occupy more space which causes tension in the rock.
Sometimes the outer layers of the rocks exert pressure on the inner or lower layers. When this pressure ceases to exist, the lower or inner layers get freed from the pressure. This also leads to weathering.
In areas of heavy rainfall soaking of rock water also causes weathering of some rocks like sandstone and conglomerate. When water penetrates such rocks, the particles get loose and separate from the main rock.

(b) What are the main types of chemical weathering?
Answer:
The process of decomposition of rocks due to changes in their chemical composition is called chemical weathering.
Its main types are:
(i) Carbonation

When the rain water mixes with the carbon dioxide in the atmosphere it leads to the formation of dilute carbonic acid.
Many rocks like limestone get easily dissolved in such acids.

(ii) Solution

Some minerals in the rock get dissolved in water.
Because of this solution, alkalis in the rock dissolve and make them brittle.

(iii) Oxidation

This process occurs in rocks which have iron present in them. The iron in the rock comes in contact with water and a chemical reaction takes place between iron and oxygen.
Hence, a reddish coloured layer forms on the rocks. This is called rust.
It occurs in rocks in areas with high rainfall.

It is the process by which rocks are broken into small fragments and fine particles due to the action of plants, animals and human beings.
The roots of the plants enter the points and ! cracks of the rocks in search of moisture.
As the roots grow bigger, they create tension in the rocks and start breaking them.
Animals such as mice, rabbits and rats dig I holes, anthills etc. and weaken the rock, which makes them loose and break into pieces.
Besides these, algae, moss1, lichen2, other flora grow in the rocks. They also help in weathering.
Thus, the weathering caused by living organisms is called biological weathering,

(d) Distinguish between weathering and mass wasting.
Answer:

Weathering	Mass Wasting
(i) Breaking or weakening of rocks is called as weathering.	(i) When weathered rock material moves down the slopes due to gravity and accumulate near the foothills or gentle slopes, it is mass wasting.
(ii) Weathering is of three types – Mechanical, Chemical and Biological.	(ii) Mass wasting is of two types – Rapid and Slow.

Fill the map with the given information and make a legend.
(1) Area affected by a landslide (mudslide) in Maharashtra.
(2) Wadgaon Darya
Maharashtra Board Class 9 Geography Solutions Chapter 3 Exogenetic Movements Part 1 3

Give geographical reasons:

Question 1.
Oxidation process occurs in heavy rainfall areas.
Answer:

The oxidation process occurs in rocks which have iron present in them.
The iron in the rock comes in contact with water and a chemical reaction takes place between iron and oxygen.
A reddish coloured layer forms on the rocks.
Thus, the oxidation process occurs in heavy rainfall areas.

Question 2.
Chemical weathering occurs in areas of heavy rainfall.
Answer:

The rain water travels through the atmosphere before reaching the ground. Carbon dioxide in the air gets mixed in the water in this process.
Dilute carbonic acid gets formed. Materials like limestone get easily dissolved in such acids leading to weathering of rocks.
Some minerals in the rock gets dissolved in water. Limestone is formed due to chemical precipitation between water and alkalis.
Similarly, because of the solution, alkalis in the rock dissolves and make them brittle.
Oxidation process occurs in rocks which have iron present in them. The iron in the rock comes in contact with water and a chemical reaction takes place between iron and oxygen.
Hence, a reddish coloured layer forms on the rocks. This is called rust.

Question 3.
Mechanical weathering3 takes place in the cold regions.
Answer:

In the cold regions, the temperature drops below 0°C for a period of time.
The water that has percolated through the cracks in the rocks freezes and turns into ice.
Ice requires greater space than water. Tension is developed when the ice tries to acquire greater space.
The continuous process of freezing and melting finally leads to the breaking of the rock mass.

Question 4.
Rapid mass movements occurs along the steep slopes.
Answer:

A thick layer of weathered material forms on the steep slopes.
When it rains in such areas, the rainwater penetrates the weathered materials and their weight increases.
Due to this the weathered materials move very rapidly and come down the steep slopes.

Question 5.
Mechanical weathering is seen in areas where the diurnal range of temperature is high.
OR
Change in temperature leads to Mechanical weathering.
Answer:

The minerals in the rocks expand because of heat and contract when the temperature decreases.
Due to such continuous contracting and expanding, tension develops in the rock particles.
Each mineral reacts differently to the temperature. Some minerals expand more, while others do not expand as much.
Consequently, the tension formed in the rocks also increases and decreases. As a result, cracks develop in the rocks and they break.
Thus in areas, where the diurnal range of temperature is higher, mechanical weathering is seen.

Question 6.
Water plays an important role in chemical weathering.
Answer:

Rock is a mixture of many minerals.
Since many things get dissolved easily in water, it is considered a universal solvent.
The solubility1 of the solution increases because the matter gets dissolved in water.
Water speeds up the process of carbonation, solution and oxidation. These processes lead to the weathering of rocks.
Thus water plays an important role in chemical weathering.

Question 7.
Frost leads to mechanical weathering.
Answer:

In areas where the temperatures drop below 0°C for quite some time, the water accumulated in the cracks and crevices in the rocks freezes.
The volume of water increases on freezing.
This leads to tension in the rocks and they shatter.
In this way frost leads to mechanical weathering.

Answer in brief:

Question 1.
What is a mass movement? What are the types of mass movements?
Answer:
The weathered rock materials move along the slopes due to gravity and accumulate near the foothills or the gentler slopes. When the weathered particles move down due to gravity alone, the process is called mass movements.

Types of Mass movements:
(i) Rapid mass movements:

A thick layer of weathered material forms on the slope. When it rains in such areas, the rain water penetrates the weathered materials and their weight increases.
The weathered materials move very rapidly and come down the slope.
Sometimes the weathered materials sink in situ. (Where they are)
Rockfalls, landslides, land subsidence are ; termed as rapid mass movements.

(ii) Slower mass movements:

Soil creep is the most common phenomenon in areas with dry climate and gentler slopes.
In periglacial regions along the soil. This is called as solifluction.

Question 2.
How does external processes occur?
Answer:

External processes occur because of the forces working on the earth’s surface.
They are mainly solar energy, gravitational force and kinetic energy associated with the moving objects on the earth’s surface.

Question 3.
What is exfoliation?
Answer:

In regions of high temperatures, the exposed part of the rock heats more while the inner part is comparatively cooler.
As a result, the outer layers of the rocks fall apart from the main rock.
This is called the exfoliation of the rock.

Question 4.
Explain the process of oxidation.
Answer:

The oxidation process occurs in rocks which have iron present in them.
The iron in the rock comes in contact with water and a chemical reaction takes place between iron and oxygen.
Hence, a reddish coloured layer forms on the rocks. This is called rust.

Explain:

Question 1.
Block Disintegration
Answer:

Sometimes both temperature and water are responsible for weathering.
The difference in temperature cause contraction and expansion of minerals in the rocks. This leads to widening theoints or cracks in the rocks.
Water accumulates in such wideouts and big blocks of rocks separate from each other.
This is called Block Disintegration.

Question 2.
Carbonation
Answer:

Carbonation is a type of chemical weathering.
The rainwater travels through the atmosphere before reaching the ground.
Carbon dioxide in the air gets mixed in the water in this process and dilute carbonic acid gets formed.
For e.g Water + Carbon Dioxide = Carbonic Acid (H₂O +CO₂ = H₂CO₃)
Materials like limestone get easily dissolved in such acids.

Question 3.
Solution
Answer:

Some minerals in the rock get dissolved in water.
Limestone is formed due to chemical precipitation between water and alkalis.
At Wadgaon Darya in Ahmadnagar district, limestone gets precipitated chemically i.e. undergoes chemical weathering again.
Similarly, because of solution, alkalis in the rock dissolve and make them brittle.

Question 4.
Make a record of few landslides that have occured in India and write about them briefly.
Answer:
Landslide is a rapid mass movement which is caused majorly due to heavy rains, floods, earthquakes etc. The following are some fatal landsides in India.

Guwahati landslide, Assam:- The landslide took place in the year 1948 due to heavy rains & over 500 people died in this landslide.
Darjeeling landslide, West Negal:- This landslide happened in the year of 1968. It was triggered by floods and thousands of people died due to this landslide.
Malpa landslide, Uttarkhand:- Consecutive landslides occured in August 1998 in village of Mapla due to which 380 people died as an entire village was destroyed in the landslide.

Answer:

2. Give an explanation:

Question 1.
The economy begins at home.
Answer:

Household finance is related to income and expenditure.
Every household has unlimited expenditure and the income earned is limited.
The household has to make a choice regarding how it has to spend its limited resources.
Management of this limited income to meet the unlimited expenses is Economics.
As we manage the finance of our family, similarly the villages/cities, states, countries and the whole world needs to have economic management. So we say Economy begins at home.

Question 2.
India’s economy is of mixed type.
Answer:

Mixed economy is a combination of Capitalism and Socialism.
India is said to be a Mixed economy because there is a co-existence of both public and the private sectors.
The private sector undertakes production for the profit motive, whereas the state tries to achieve social welfare.
India, therefore, tries to achieve a balance between maximum social welfare for its citizens on one hand and profit on the other. Therefore, India’s economy is of Mixed type.

Question 3.
On the basis of economies, we can divide countries into three groups.
Answer:
The activities related to the production, distribution and consumption of goods and services in a specific region is called economy. On the basis of economies, countries are divided into three groups. Capitalist Economy, Socialist Economy and Mixed Economy.

Capitalistic Economy is a kind of economy in which the means of production is in the hands of the private sector, e.g. Germany, Japan, the U.S.A.
Socialist Economy is a kind of economy in which the means of production belongs to the society i.e. the government’s control, e.g. China, Russia.
Mixed Economy is a kind of economy in which there is a co-existence of both private and public sectors, e.g. India, Sweden, the U.K.

3. Write the following questions in one line:

Question 1.
To which economic factor is the management of individual or family finances related?
Answer:
Management of individual or family finances is related to the economic factor of ‘income and expenditure.

Question 2.
From which Greek word is the term ‘Economics’ derived?
Answer:
The word ‘Economics’ is derived from the Greek word ‘Oikonomia’ which means family management.

(i) ‘V’ Shaped Valley:

A ‘V shaped valley is formed due to the erosional work of a river.
Over a period of time, the amount of load in the flow starts increasing.
More and more energy of the river gets consumed in transporting the material.
As a result, there is less erosion of the bed. The erosion along the banks and the slopes of the valley increases.
Hence, the slopes recedes and the valley with near-vertical sides becomes wider, resembling the letter ‘V’.

(ii) Gorge:

A gorge is found in the upper course of the river.
It is a deep and narrow valley with steep sides.
In mountainous areas, the river flows with great speed. Therefore, the bed of the river gets eroded more than its banks, giving rise to a gorge that has a steep banks and a narrow bed.

(iii) Waterfall:

Waterfalls are formed as a result of the erosional work of a river.
Water flowing over a hilly region cascades down a cliff, forming a waterfall.
In the areas, where the hard and soft rocks are next to each other, the soft rocks are eroded faster than the hard ones. A difference in the height along the river bed leads to the formation of a waterfall.

Question 2.
Which agent is responsible for the formation of stalactites and stalagmites and where are they formed?
Answer:

The work of groundwater is responsible for the formation of stalactites and stalagmites.
In areas of limestone, the alkaline water seeps through the roof of the limestone caves.
When this water evaporates, minerals get deposited at the bottom and at the top of the limestone caves.
This leads to formation of stalactites and stalagmites.

Question 3.
List the landforms that are produced by the depositional work of the sea waves
Answer:
The landforms like beaches, sand bar, lagoons are formed due to depositional work of the sea waves.
(i) Beach:

Large amount of sediments come from the landward side in areas between two adjoining headlands.
Moreover, as these areas are shallow, the velocity of the waves decreases.
As a result, the sediments that come from the land, as well as those coming from the deep sea, get deposited in this area.
Predominantly fine sand gets settled along the coast.
Such sandy deposits along the coasts are called beaches.

(ii) Lagoon:

The brackish water separated from the seawater by sand bars and lying in the areas between the coast and bars is called a lagoon.
As the waters are separated from the open sea, large waves are not generated.
These lagoons run parallel to the sea coast.

(iii) Sand bars:

Sand gets deposited along the sides of the headlands.
The deposition extends parallel to the coast from one headland to the next.
Over a period of time, these deposits extend over long distances forming bars that protrude into the water at some distance away from the beach.
These are known as ‘sand bars’, Sometimes, the eroded material from the’ beach, gives rise to the sand bars.

Question 4.
Name the types of moraines.
Answer:
The glaciers carry sediments with them. These sediments are called moraines. Depending ond the location of the deposits, moraines can be divided into 4 types: ground moraines, lateral moraines, medial moraines and terminal moraines.

The material deposited at the base of a glacier is called ground moraine.
The material deposited along the banks of a glacier is called Lateral moraine.
After the confluence of two glaciers, the moraine deposited in the central part of the glacier is known as medial moraine. It is formed out of . the side moraine of the inner banks of the two glaciers.
At the end where a glacier turns into a stream, huge quantity of moraine is deposited. The stream of water is unable to carry the moraine further. As the deposited moraine is at the terminal part of a glacier, it is called terminal moraine.

Answer:
Maharashtra Board Class 9 Geography Solutions Chapter 4 Exogenetic Movements Part 2 30

Can You Tell?

Question 1.
How will you differentiate between a rill, gully, stream and a river?
Answer:
The smallest natural flow of rain water is a rill. Many rills come together to form a gully. Many gullies come together and form a stream. Many streams come together and form a river. Thus we can see that rills, gullies, streams nad rivers are the various forms of flowing water in increasing order of their size.

Question 2.
What is a river?
Answer:
Running water flows naturally in a direction according to gravity along the slope, making its own way. This is called a flow of water when many such flows of water come together a river is formed.

Question 3.
Where can you see the work by glaciers in India?
Answer:
Glaciers can be seen in the Himalayan region in India.

Question 4.
In which natural region can you see the work of glaciers at the sea level?
Answer:
We can see the work of glacier at sea level in the Polar regions (Antarctica).

Question 5.
Where will you find the landforms formed by sea waves along the Konkan coast?
Answer:
Along the Konkan coast, landforms formed by sea waves can be found at Harihareshwar, Bhagwatibandar, Shrivardhan, Ratnagiri and Sindhudurg.

Think about it.

Question 1.
There are many creeks found in the coastal areas of Konkan but no delta, why?
Answer:
The Konkan coast has an indented (broken) coastline. Hence many creeks are found here. Many small seasonal rivers originate in the steep western side of the Western Ghats. As the rivers flow through the steep slopes their velocity increases. So, there is very little erosion done by them. Due to the narrow width of the Konkan coast, the rivers cover a short distance and drain in the Arabian sea. Thus they do not form estuaries rather than deltas.

Question 2.
Can you see a glacier moving just as you can observe the movement of river water?
Answer:
No

Question 3.
Ramu has to dig a well in his farm. But he is in a dilemma as to which season should he dig it so that there is water supply for a longer time. What will you suggest to Ramu?
Answer:
Ramu should dig a well during the summer season. A deep well can be dug during the summer season. This will ensure water supply not only during the monsoon and winter season but also during the next summer season.

Question 4.
Which agent has more kinetic energy of all-wind, river or glacier?
Answer:
Glacier is the agent of erosion which has the most kinetic energy of all. The glacier is a mixture of heavy soil and rock particles which are flowing. Thus it has both weight and movement.

Find out.

Question 1.
Is there any lake found near the meanders of the river? Obtain information about them.
Answer:

Ox-Bow lakes are usually found near the meanders of a river.
Wherever the river changes its direction, erosion takes place along the outer banks.
If these conditions occur again and again, the river develops a zigzag path.
Such a zigzag path is called a meandering path (course) and each loop along the path is called meander.
When the turns in the course become acute, the limbs of a turn come very close.
During flood, as the force of water increases, the river skips the meandering path and follows a straight path.
The abandoned portion of the loop develops into a lake that is called an ‘ox-bow’ lake.

Question 2.
Where will you find mushroom rocks in the Deccan Plateau?
Answer:
Mushroom rocks can be found in the Hyderabad.

Question 3.
Can you find the work of wind near coastal areas? What landforms will be formed there?
Answer:
Yes, Ripple marks and sand mounds can be seen on the sand in the coastal regions.

Question 4.
Where are limestone caves, stalactites and stalagmites found in Maharashtra?
Answer:
Limestone caves, stalactites and stalagmites are found in Kanhur caves in the Ahmednagar district of Maharashtra.

Question 5.
Why are the landforms formed in limestone called Karst?
Answer:
A karst is an area of land formation created by eroding and dissolving portions of limestone or other soluble rock layers above or below the ground. According to the prevalent interpretation, the term is derived from the German name for the Karst region, a limestone plateau above the city of Trieste in the northern Adriatic.

Answer:
Maharashtra Board Class 9 Geography Solutions Chapter 4 Exogenetic Movements Part 2 29

Give geographical reasons:

Question 1.
Like the river, a glacier too carries out the work of erosion, transportation and deposition.
Answer:

In regions, where the temperatures are generally below freezing points, precipitation is in the form of snowfall.
Layers of snow accumulate on the earth’s surface because of snowfall.
The heavy weight of these overlying layers makes the snow move along the slope.
At the base of the layer, the snow starts melting because of the friction and the pressure from above. Glacier starts moving slowly along the slope.
Thus like the river, a glacier too carries out the work of erosion, transportation and deposition.

Question 2.
Specific landforms are formed due to deposition by wind in arid and semi arid regions.
Answer:

Sand particles that blow with the winds are of different shapes and sizes.?
Those particles which are very fine are carried to larger distances while the larger ones get transported to shorter distances only.
These sand particles get deposited in deserts and semi-arid climates.
As a result, specific landforms are formed.
Sand dunes, barchans, seifs, ripple marks, loess plains, etc. are formed by deposition by wind.

Question 3.
The work of sea waves cause different landforms.
Answer:

In coastal areas, the sea waves carry out erosional, depositional and transportational work.
Winds and tides cause the movements of sea water. As a result, waves come to the coast.
Because of their hitting the rocks at the coasts, erosion of the rocks occurs.
The landforms like wave cut platforms, sea caves, sea arches, sea cliffs, etc. are formed because of the erosional work of the waves.
The landforms like beaches, sand bar, lagoons are formed due to depositional work of the sea waves.

Question 4.
In the desert, the work of wind is effective.
Answer:

The work of wind is predominantly found in the hot desert and semi-arid regions.
Hot deserts are found close to the Tropic of Cancer and Tropic of Capricorn.
The average annual rainfall in the hot deserts is 250 mm or even less. Therefore, the vegetal cover is negligible.
As there are no obstacles due to lack of vegetal cover, the work of wind is effective in the desert.

Question 5.
Glaciers have a low velocity.
Answer:

In the high altitude areas and the areas of high elevation, the ice slides down the slope. Such a sliding mass of ice is called a glacier.
As the ice moving in a glacier is in the solid state, its velocity is very low.
The thickness of the accumulated ice, the temperature and the slope of the land are the factors that determine the velocity of the glacier.

Question 6.
The ground water level changes according to seasons.
Answer:

The upper level of the stored ground water is called ground water level.
It varies according to the slope of the land, porosity and compactness of the rocks and the rainfall in the region.
Ground water level also changes according to season.
In the rainy season, it is closer to the ground surface whereas during summer, it drops down deeper.

Answer:
Stalactite and Stalagmite cave.

Answer the following questions in brief:

Question 1.
List the agents responsible for new landforms. i
Answer:
The agents – running water (river), glaciers, wind, sea waves and groundwater, – do the work of erosion, transportation and deposition. Because of these agents, the earth’s surface keeps undergoing changes and new landforms are formed.
(i) Running water (river):

The river beds, as well as the banks of a river, are eroded due to the speedy flowing stream of water. The load that a river carries also erodes the banks and the bed of the river.
The rocks, stones, sand, etc. collide with one another and break into fragments
Different landforms like gorge, V-shaped valley, pothole and waterfall are formed due to the erosional work of a river.

(ii) Glaciers:

As a glacier is nothing but a solid mass of ice, its velocity is very low. Nevertheless, the mass of water in the solid form is quite high. Therefore, glaciers cause a considerable amount of erosion.
The glaciers erode the ice-clad base of the mountain slopes and the snow-clad sides of the mountains to a large extent.
The Cirque, Arete and horn, U-Shaped valley and hanging valley are the landforms formed by the erosional work of a glacier.

(iii) Wind:

The wind carries sand and pebbles.
When they strike and scratch the rocks, the elevated and basal parts of the rocks get eroded.
Due to the erosional processes of the wind, deflation hollows, mushroom rocks and yardangs3 are formed.

(iv) Sea waves:

The basal portions of the headlands get severely eroded due to the continuous attack of sea waves. This leads to the erosion of the rocks on a large scale.
Rocky coasts are formed where the headlands get severely eroded.
Landforms such as sea cliffs, sea caves, wave- cut platforms, sea arches and sea stacks are formed due to the erosional work of sea waves.

(v) Groundwater:

Soluble minerals in the rocks dissolve in water and they move along with the ground water. This process is called erosion by ground water.
The work of ground water is predominant in the region where rock like limestone is found on a large scale.
Limestone dissolves in carbonic acid. Carbonic acid is formed due to the presence of carbon? dioxide in ground water. This acid dissolves carbonates like limestone. Thus, chemical weathering takes place.
The landforms like sinkholes and caves are the result of the erosional work of groundwater.

Question 2.
List the landforms that are produced due to deposition of sediments by rivers.
Answer:
Landforms like flood levees, flood plains, deltas are formed because of deposition of sediments,

Flood levees: When in flood, the river deposits ; the coarser material on the banks which in duecourse rises parallel to the banks of the river. These are called ‘flood levees’.
Flood plains: The finer silt deposited away from the banks during the flood form plains on ! either side of the river. They are called ‘flood plains’.
Delta: The continuous deposition leads to the formation of a plain in the shape of a triangle called delta. Extensive deltas have been formed ! at the mouth of rivers Ganga, Godavari, Kaveri.

Question 3.
Write in detail about the erosional and depositional work of wind.
Answer:
(i) Erosional work of winds:

Wind carries small sand particles, small pebbles, etc. along with it.
These particles cause erosion along rocks coming in the way due to friction.
This leads to formation of mushroom rocks, deflation hollows, yardangs, etc.

(ii) Depositional work of winds:

Sand particles that blow with the winds are of different shapes and sizes.
Those particles which are very fine are carried to larger distances while the larger ones get transported to shorter distances only.
These sand particles get deposited in deserts and semi-arid climates. As a result, specific landforms are formed.
Sand dunes, barchans, seifs, ripple marks, loessplains, etc. are formed by deposition by wind.

Question 4.
Write in detail about the erosional and depositional work of sea waves.
Answer:
(i) Erosional work of sea waves:

When the waves break at the coast, they bring with them water, transported stones, pebbles,sand particles, etc. This leads to the erosion of the coast.
Because of the chemical and hydraulic action of the sea wave too, the erosion occurs. The landforms like wavecut platforms, sea caves, sea arches, sea cliffs, etc. are formed because of the erosional work of the waves.

(ii) Depositional work of sea waves:

The eroded materials accumulate at the sea bed. Because of tides, they keep on moving towards the coast and away from the coast.
They become fine because of attrition and hitting towards each other.
Deposition of such materials occurs at the places where the effect of waves is less. The landforms like beaches, sand bar, lagoons are formed due to the depositional work of the sea waves.

Explain:

Question 1.
Erosional work of rivers
Answer:

The rivers originate at a much higher altitude from the sea level.
Here, the river flows at a great speed and therefore, its power to erode is great.
The riverbed and the river banks get eroded because of the speedy flow of the river, sand particles, pebbles. Also, various tributaries join the main river.
All these lead to the formation of gorges (canyons), V-shaped valleys and waterfalls.

Question 2.
Transportation and deposition by rivers
Answer:

A river flows down the slope from a hilly region.
At the foothills, the change in the slope causes deposition of coarse sediments.
As these are deposited in a triangular shape, they form an alluvial fan. As the steepness of the slope decreases and the transport capacity of the river reduces, it starts flowing slowly.
It bends (meanders) often in its way in an effort to cross even small obstacles.
By the time the river reaches the sea, its riverbed becomes very wide and its speed becomes very slow.
The sediments of the river get deposited in its bed and on its banks. The factors that determine the deposition of sediments are thelength of the rivers, volume of water, amountof sediments, and the slope of the river and the earth’s surface.
Thus, landforms like flood levees, flood plains,deltas are formed because of deposition of sediments.

Question 3.
Erosion work by glaciers
Answer:

Though the velocity of glaciers is less, the mass of the ice is more and hence the glacier erodes its own banks and its bed on a large scale.
The erosional work of glaciers produces landforms like cirques, aretes, horns, U-shaped valleys, hanging valleys and roche moutonnees (or sheepbacks).

Question 4.
Transportation and deposition by glaciers
Answer:

The glaciers carry sediments with them. These sediments are called moraines.
Depending on the location of the deposits, moraines can be divided into 4 types: ground moraines, lateral moraines, medial moraines and terminal moraines.
The depositional work of glacier produces landforms like drumlins, eskers, etc.

Question 5.
Erosional and depositional work of wind
Answer:

Erosional work of wind: Wind carries smallsand particles, small pebbles, etc. along with I it. These particles cause erosion along rockscoming in the way due to friction.
This leads to formation of mushroom rocks, deflation hollows, yardangs, etc.
Depositional work of winds: Sand particles that blow with the winds are of different shapes and sizes.
Those particles which are very fine are carried to larger distances while the larger ones get transported to shorter distances only.
These sand particles get deposited in deserts ; and semi-arid climates. As a result, specific landforms are formed.
Sand dunes, barchans, seifs, ripple marks, loess plains, etc. are formed by deposition by wind.

Question 6.
Erosional work of sea waves
Answer:

When the waves break at the coast, they bring with them water, transported stones, pebbles, sand particles, etc.
This leads to the erosion of the coast. Because of the chemical and hydraulic action of the sea wave too, the erosion occurs.
The landforms like wave cut platforms, sea caves, sea arches, sea cliffs, etc. are formed because of the erosional work of the waves.

Question 7.
Depositional work of sea waves
Answer:

The eroded materials accumulate at the sea bed.
Because of tides, they keep on moving towards the coast and away from the coast.
They become fine because of attrition and hitting towards each other. Deposition of such materials occurs at the places where the effect of waves is less.
The landforms like beaches, sand bar, lagoons are formed due to depositional work.

Question 8.
Work of groundwater and landforms
Answer:

The rainwater seeps below the earth’s surface through porous rocks or the cracks in the rocks.
This water accumulates at the non-porous layer of the rock. This accumulated water is called groundwater.
The soluble minerals in the water get dissolved and flow with the groundwater. This is the erosional work of the groundwater.
When the groundwater evaporates or the volume of soluble minerals is more than the solubility of the groundwater, the deposition of dissolved materials starts.
Landforms like sinkholes, limestone caves, stalactites and stalagmites are formed.
Thus, the groundwater carries out the erosion, transportation and depositional work.

Question 9.
Groundwater table
Answer:

The upper surface of the water accumulated below the ground is called the ground water table.
Factors like seasons, porosity of rocks, amount of rainfall, etc. affect the level of water table.
The water table is closer to the ground during rainy seasons while it is deeper in the summers.?
