Answer:

1 – e – iii
2 – c – i
3 – d – v
4 – b – ii
5 – a – iv

2. Give geographical reasons:

Question 1.
Tides are influenced more by the moon than the sun.
Answer:

• The gravitational pull of the moon and the sun as well as that of the earth is one of the factor responsible for occurrence of tides.
• But compared to the sun, the moon is closer to the earth.
• Due to this the gravitational force of the moon becomes more effective than that of the sun.
• Therefore, tides are influenced more by the moon than the sun.

Question 2.
At some places along the coast, the low lying areas turn into lagoons or marshy lands.
Answer:
(i) Generally the areas along the sea coast are low lying and get flooded easily by the sea water during high tide.

(ii) This leads to accumulation of sea water over a long period of time leading to formation of swamps & marshes.

(iii) The tides help in maintaining the mangroves and the coastal biodiversity here.

(iv) Certain areas near the sea coast being low lying & waters being shallow also lead to sediment deposition by sea waves leading to formation of lagoons.

(v) In this way, at some places along the coast, the low lying areas turn into lagoons or marshy lands.

Question 3.
Place located on the opposite meridian experiencing high or low tide will also experience high or low tide respectively.
Answer:
(i) The gravitational force of moon, the sun & the earth and the centrifugal force generated due to the rotation of the earth are two major factors responsible for the occurrence of tides.

(ii) When a place (meridian) faces the moon the gravitational force of the moon exceeds the centrifugal force of the earth leading to high tide here as the water is pulled towards the moon.

(iii) At the same time the place on the earth located at the opposite meridian to the place experiencing high tide, the centrifugal force of the earth exceeds the gravitational force of the moon. Thus, the water is pulled in the direction away from the moon leading to high tide.

(iv) The water required for the high tide moves in from places that are at right angles to those having high tides causing a low tide at those places.

(v) Thus, place located on the opposite meridian to the place experiencing high or low tide will also experience high or low tide respectively.

3. Answer in brief:

Question 1.
If there is high tide at 7 am, find the timings of the next high and low tides on the same day at a given place.
Answer:

• There is high tide & low tide twice a day i.e. in 24 hours.
• One cycle of high tide & low tide is completed after every 12 hours & 25 minutes.
• If there is a high tide at 7 am, the next low tide will be at 1.12 pm (after 6 hrs & 12 min.) & the next high tide will be at 7.25 pm (after 12 hrs & 25 min.)

Question 2.
If at Mumbai (73° E meridian), there is high tide at 1.00 pm on Thursday, then on which other meridian will there be a high tide too? State with reasons.
Answer:
The other meridian which will experience high tide will be 107°W (180°-73°) because it is exactly 180° opposite from 73°E.

Question 3.
Explain the reasons for the generation of waves.
Answer:

• The main reason of wave generation is the force of the wind i.e. water appears to be moving.
• But at times waves get generated due to earthquake or volcanic eruptions occurring below the floor of the sea.
• Large or small waves are formed continuously at the surface of the sea.
• Generation of waves is a natural and regular phenomenon.

4. In what way will the following depend on the tides:

Question 1.
Swimming:
Answer:
A lack of an understanding of the timings of high and low tides may cause accidents to swimmers entering the sea.

Question 2.
Steering a ship:
Answer:
Ships can move up to the ports during high tide.

Question 3.
Fishing:
Answer:
With the high tide, fish moves into the creeks and this helps the fishing activity.

Question 4.
Salt Pans:
Answer:
During high tide, seawater can be stored in salt pans from which salt can be obtained.

Question 5.
Going to coastal areas for trips:
Answer:
Plan for going to trips after full moon or new moon day. Also one must have details about the timings of the tides for better enjoyment.

5. Observe figure of neap tide and answer the following questions:

Question 1.
Which phase of the moon does it show?
Answer:
The diagram shows the phase of the quarter moon.

Question 2.
What are the relative positions of the moon, the sun and the earth?
Answer:
The moon, the earth and the sun make an angle of 90° (right angle)

Question 3.
What effect will it have on the tides?
Answer:
It will lead to neap tide. Due to such conditions during high tide the water level will rise less than usual while during low tide water level will fall less than usual.

6. Differentiate between:

Question 1.
High tide and low tide:
Answer:

High tide	Low Tide
(i) The rise in the level of sea water is caused by the combined effect of centrifugal and gravitational force of the moon and the sun.	(i) The fall in the level of sea water is caused by the combined effect of centrifugal and gravitational force of the moon and the sun.
(ii) At the time of high tide, sea water is very close to the coast.	(ii) At the time of low tide, sea water is far away from the coast.

Question 2.
Spring tide and neap tide.
Answer:

Spring tide	Neap Tide
(i) It occurs on the new moon day and the full moon day.	(i) It occurs on the the first and the third quarter days.
(ii) The gravitational pull of the moon and the sun as well as that of the earth are in a straight line and act in the same direction.	(i) The gravitational pull of the moon and the sun are at right angle.
(iii) Spring tides are a little higher than the average high tides and a little lower than the average low tides.	(iii) Neap tides are a little lower than the average high tides and little higher than the average low tides.

7. Describe the positive and negative effects of tides:
Answer:
The positive effects of tides are as follows:

• The tides clear the waste and hence the coasts become clean.
• Ports do not get filled with sediments .
• Ships can move up to the ports during high tide.
• During high tide, sea water can be stored in salt pans from which salt can be obtained.
• The tidal force can be used to generate electricity.
• With the high tide, fish move into the creeks and this helps fishing activity.
• The tides help in maintaining the mangroves and the coastal biodiversity.

The negative effects of tides are as follows:

• A lack of an understanding of the timings of high and low tides may cause accidents to swimmers entering the sea.

Activities:

1. Visit the nearest sea coast. From a higher location, observe the waves approaching the coast. See if the approaching waves change their direction. With the help of your teacher find the answer to why this change occurs.
2. Collect information from the internet about how electricity is generated from waves. Find places where such electricity is being generated.

Class 7 Geography Chapter 3 Tides InText Questions and Answers

Differentiate between:

Question 1.
Centrifugal force and Gravitational
Answer:

Centrifugal force	Gravitational force
(i) Due to rotation, the earth gets a type of power of force. This force works away from the centre. It is called centrifugal force. (ii) Centrifugal force works away from the centre. (iii) Due to centrifugal force an object on the earth would be thrown into the space.	(i) Gravitational force is working towards the centre of the earth. This force is many times greater than the centrifugal force. (ii) Gravitational force works towards the centre. (iii) Due to gravitational force an object on the surface of the earth remains at the place where it exists.

Write short notes:

Question 1.
Spring tide
Answer:
(i) On new moon & full moon days, the gravitational pull of the sun and the moon act in the same direction due to which the total pull increases.

(ii) Hence, the tide on these days is much higher than the average high tide.

(iii) This is known as spring tide.

Question 2.
Neap tide
Answer:
(i) While revolving around the earth, the moon makes a right angle with respect to the earth and the sun, twice a month.

(ii) This position occurs on the first and third quarter of each month. On both these days the forces of both the sun & the moon operate at right angles on the earth.

(iii) At the places where the sun causes high tide, the gravitational pull of the moon which is at right angles also acts on the water.

(iv) Due to such conditions the water level rise is less than usual at the time of high tide. Similarly, fall in water level is less than usual at the time of low tide.

(v) Such tides are called neap tides.

Question 3.
Waves
Answer:

• The sea water gets pushed by the wind and ripples are generated on the water surface. These are called waves.
• The sea water moves up & down or slightly forward & backward due to the waves.
• The waves bring the energy contained in them to the coast.
• Large & small waves are formed continuously at the surface of the sea.
• Generation of waves is a natural & regularly occurring phenomenon.

Question 4.
Struture of the waves
Answer:
(i) The sea water gets pushed up & down because of the wind. The raised up portion of the wave is called crest & the depressed one is called trough.

(ii) The vertical distance between a crest and the following trough is called the amplitude of the wave whereas the distance between two successive crests or troughs is called wave length.

(iii) The wave length, its amplitude & its velocity depend on the velocity of the wind.

Answer:

5. Answer the following:

Question 1.
Why do the sun, the moon and the earth not lie in one and the same line on every full moon and new moon day?
Answer:
(i) The orbital path of the earth and that of moon are not in the same plane.
(i) The moon’s revolutionary orbit makes an angle of about 5° with that of the earth.

When a total solar eclipse occurs why is the partial eclipse also seen from the earth?
Answer:
(i) On a new moon day if the sun, the moon & the earth fall in one line & are in the same plane, the shadow of the moon falls on the earth

Use your brain power:

Question 1.
On the day of solar eclipse, in which part of the earth will it not be seen?
Answer:
Solar eclipse will not be seen where there is night.

Question 2.
Can we see total and annular solar eclipses on the same occasion?
Answer:
No, total and annular solar eclipses cannot be seen on the same occasion.

Question 3.
Why is an annular lunar eclipse not seen?
Answer:
An annular lunar eclipse cannot be seen because:

• The size of the earth is bigger than that of the moon.
• As compared to the sun, the moon is close to the earth.
• Therefore, it is not possible that a dark shadow of the earth is cast in space & does not reach the moon.

Question 4.
Which eclipses will you see from the moon?
Answer:
Solar eclipses can be seen from the moon.

Question 5.
Why are solar eclipses caused by the other planets not seen from the earth?
Answer:
(i) A Solar eclipse occurs when the moon comes in between the sun & the earth & all of them are in the same plane & fall in one line on a new moon day.
(ii) Similarly, when Venus & Mercury come in between the earth & the sun, they make a small speck against the surface of the sun as they are too far away.
(iii) The other planets have orbits outside the earth’s & cannot fall in line between the earth & the sun.
(iv) Hence, the solar eclipse caused by other planets are not seen from the earth.

Think about it:

Question 1.
Figure shows positions of the moon as seen from the space and as seen from the earth. How will you identify which are which?

Answer:
Half of the moon’s portion is illuminated by the sun, and the other half remains dark. However, only some part of this illuminated portion of the moon can be seen from the earth. The position of the moon from the Earth is as follows:

• New moon
• Waxing crescent
• 1st Quarter

Question 2.
Like sunlight and moonlight, is there anything called the earth light? If yes, where do you think it is found?
Answer:
Yes, Earthlight is the partial illumination of the dark portion of the moon’s surface by light reflected from the earth’s airglow.

Question 3.
When solar eclipses do not occur on a new moon day, does it mean that the moon does not have any shadow at all?
Answer:
The moon casts a shadow on every new moon day, but solar eclipse occurs only when the moon’s shadow falls on the earth.

Answer:
Total & Partial Solar eclipses occur in perigee position.

Question 6.
When does a lunar eclipse occur?
Answer:
A lunar eclipse occurs when the moon enters the shadow of the earth while revolving around it.

Give geographical reasons for the following statements:

Question 1.
We constantly see only one and the same side of the moon.
Answer:

• The time, the moon takes to make one revolution around the earth and one rotation around itself is the same.
• As the axial and the orbital motions of the moon are almost of the same duration, only one, the same side of the moon faces the earth.
• Therefore, we constantly see only one and the same side of the moon.

Question 2.
The distance between the moon and the earth keeps on changing.
Answer:

• The moon’s orbit of the revolution is elliptical to that of the earth.
• Hence the distance of the moon from the earth is not the same everywhere along its orbit while revolving.
• When it is the closest to the earth it is said to be in perigee and when it is at the farthest, the position is called apogee.

Question 3.
Eclipses do not occur on each new moon or full moon day.
Answer:

• The orbital path of the earth and that of the moon are not in the same plane.
• The moon’s revolutionary orbit makes an angle of about 5° with that of the earth.
• So, the sun, the earth and the moon may not be in one straight line in the same plane on every new moon or full moon day.
• Hence, eclipses do not occur on each new moon or full moon day.

Question 4.
The Annular solar eclipse is rarely seen.
Answer:
The Annular solar eclipse is rarely seen because

• The moon is in apogee position.
• The deep shadow of the moon is cast in space and does not reach the earth.
• From a very small region of the earth, only an illuminated edge of the sun disc is seen in the form of a ring.

Question 5.
Birds and animals are confused during the solar eclipse.
Answer:
Birds and animals are confused during the solar eclipse because –

• Untimely darkness sets in.
• The event does not suit their biological clock.
• Their response to the event is also unusual.

Question 6.
On the first and third quarter days, the moon appears semicircular in shape.
Answer:

• On the first and third quarter days, the moon, the earth and the sun make an angle of 90°
• At these positions, we see half the portion of an illuminated moon.
• Hence, in the sky, the moon appears semi-circular in shape.

Answer the following:

Question 1.
What precautions should we take while observing a solar eclipse?
Answer:
The precautions to be taken while observing a solar eclipse are:

• We should not observe a solar eclipse with naked eyes as the intense light of the sun can harm them.
• We must use dark glasses or goggles that are specially designed for viewing the solar eclipse.

Question 2.

Answer:
Total and Partial solar eclipse will occur in perigee condition.
(i) Total solar eclipse :

• On a new moon day, the sun, the moon the earth are in a straight line & the shadow of the moon falls on the earth
• The area of dark shadow falls on the earth, the sun becomes completely invisible. This condition is known as total solar eclipse.

(ii) Partial solar eclipse:

• However during the same period at places where the shadow is lighter, the sun disc appears partially covered,
• This condition is described as partial solar eclipse.

Question 3.
How are lunar eclipses formed?
Answer:
(i) A lunar eclipse occurs when the moon enters the shadow of the earth while revolving around it.
(ii) On a full moon day if the sun, the earth & the moon, are in a straight line, the orbital path of the moon passes through the dark shadow of the earth.
(iii) If the moon is totally hidden within the shadow, a total lunar eclipse is seen & if only a part of the moon is in the shadow, a partial lunar eclipse is seen.

Write short notes on:

Question 1.
Characteristics of solar eclipse.
Answer:

• A solar eclipse occurs on a new moon day, but not on every new moon day.
• If and only if, the sun, the moon and the earth are in the same plane and fall in one line, the solar eclipses occur.

Balbharti Maharashtra State Board Class 7 Geography Solutions Chapter 4 Air Pressure Notes, Textbook Exercise Important Questions and Answers.

Maharashtra State Board Class 7 Geography Solutions Chapter 4 Air Pressure

Class 7 Geography Chapter 4 Air Pressure Textbook Questions and Answers

1. Give reasons:

Question 1.
Air pressure decreases with increasing altitude.
Answer:

• The proportion of dust in the air, water vapour, heavy gases, etc. is higher in the air and closer to the surface of the earth.
• This proportion decreases with increasing altitude.
• As one moves higher and higher from the surface of the earth, the air becomes thinner and thinner.
• As a result, the air pressure decreases with increasing altitude.

Question 2.
Pressure belts oscillate.
Answer:

• The duration and the intensity of sunrays varies during particular periods of the year in both the hemispheres.
• So, the locations of the temperature zones and the pressure belts dependent on the sun’s heat also vary.
• This change is of the order of 5° to 7° towards the north in Uttarayan1 and 5° to 7° south in Dakshinayan2.
• In this way pressure belts oscillate.

2. Give short answers to the following questions.

Question 1.
What effect does temperature have on air pressure?
Answer:

• Temperature and air pressure are closely related. Wherever the temperature is high, the air pressure is low.
• As the temperature rises, the air gets heated, expands, and becomes lighter.
• This lighter air in the vicinity of the earth’s surface starts moving up towards the sky
• As a result, the air pressure in such areas decreases.

Question 2.
Why is the subpolar low pressure belt formed?
Answer:

• Due to earth’s curvature, the area between two parallels gets reduced as we move towards the poles.
• This results in lesser friction1 of the air with the earth’s surface.
• Air in this region is thrown out because of this reduced friction and also because of the earth’s rotational motion.
• This leads to the development of a low pressure belt in the sub polar region i.e. in area between 55° & 65° parallels in both the hemispheres.

3. Write notes on:

Question 1.
Mid-latitudinal high pressure belts.
Answer:

• The heated air from the equatorial region becomes lighter, starts ascending and after reaching higher altitudes, moves towards the polar region, i.e., towards the North and the South Pole.
• Due to low temperatures at the higher altitudes, the air cools down and becomes heavier.
• This heavier air descends down in both the hemispheres in the region between 25° to 35° parallels.
• This leads to the formation of high pressures, belts in these parallels of latitudes in both the hemispheres.
• This air is dry, hence the region does not get rainfall.
• Consequently, most of the hot deserts on the earth are found in these regions.

Question 2.
Horizontal distribution of air pressure.
Answer:

• The heat received from the sun is uneven in different regions.
• The distribution of temperature is uneven from the equator to the poles.
• This difference can lead to difference in air pressure.
• There are four air pressure belts formed on the earth surface.
• Equatorial low-pressure belt between 5°N and 5°S parallels as the temperature is high here.
• Mid latitudinal high-pressure belt between 25° and 35° parallels due to descending heavier air.
• Subpolar low-pressure belt formed between 55° and 65° parallels due to friction and rotation.
• Polar high-pressure belt formed between 80° and 90° parallels due to low temperatures.

4. Fill in the gaps with the appropriate option.

Question 1.
At higher altitudes air becomes ________. (thicker, thinner, hotter, more humid)
Answer:
thinner

Question 2.
Air pressure is expressed in _______ .(millibars, millimeters, milliliters, milligrams)
Answer:
millibars

Question 3.
On the earth, air pressure is _______.(uniform, uneven, high, low)
Answer:
uneven

Question 4.
The ______ pressure belt spreads between 5° North and 5° South parallel. (equatorial low, polar high, subpolar low, mid-latitudinal high)
Answer:
equatorial low

5. How does a high-pressure belt get formed near 30 ° parallel? Why does this region have hot deserts?
Answer:
(i) The heated air from the equatorial region becomes lighter, starts ascending and after reaching higher altitudes, moves towards the polar region, i.e., towards the North and the South Pole.

(ii) Due to low temperatures at the higher altitudes, the air cools down and becomes heavier. This heavier air descends down in both the hemispheres in the region between 25° to 35° parallels.

(iii) This leads to the formation of high pressures belts in these parallels of latitudes in both the hemispheres.

(iv) This air is dry, hence the region does not get rainfall. Consequently, most of the hot deserts on the earth are found in these regions.

6. Draw a neat diagram showing pressure belts. Label the diagram.

Question 2.
With which pressure belt are the polar winds associated? In which temperature zone are they observed?
Answer:
The polar winds are associated with polar high pressure belt and sub polar low pressure belt. It is observed in the frigid zone.

Question 3.
What could be the reason behind a low pressure belt in the Tropics?
Answer:
Low pressure belt is formed in the tropics because the temperature is high.

Question 4.
With which pressure belts are the winds in the Temperate zone associated?
Answer:
The winds in temperate zone are associated with mid latitudinal high pressure belt.

Question 5.
Write the latitudinal extent of the low pressure belts.
Answer:
The latitudinal extent of Equatorial low pressure belt is between 50°N & 50°S parallel & the latitudinal extent of the sub polar low pressure belt is between 55° & 65° parallel in both the hemispheres.

Question 1.
The nature of the isobars.
Answer:
The isobars are joining places of equal air pressure on the map.

Question 2.
High and low pressure belts and their latitudinal position.
Answer:
(i) The latitudinal position of high pressure belt is between 25° & 35° parallels and between 80° & 90° parallels in both the hemisphere
(ii) The latitudinal position of low pressure belt is between 0° & 5° parallels and between 55° & 65° parallels in both the hemispheres.

Question 3.
The direction of the isobars and the distance between successive isobars over the oceans and continents.
Answer:
(i) In the northern hemisphere most of the isobars are in southwest to north east direction over the continents. Also the distance between the isobars varies.

(ii) Closely spaced isobars indicate large pressure changes over a small area. Widely spaced isobars indicate gentle or gradual pressure change.

(iii) In the southern hemisphere, the isobars extend  in east-west direction. The distance between the isobars is fairly constant over the oceans & so the isobars are fairly parallel to each other.

Question 4.
Comparison of the isobars in the northern and the southern hemispheres.
Answer:
In the northern hemisphere the isobars are far spaced and uneven, whereas in the southern hemispheres it is closely spaced and parallel.

Question 1.
Study the temperative distribution map given in your std VI textbook and the pressure distribution map in this lesson to find the correlation between air temperature and air pressure.
Answer:

• The temperature deceases continuously from the equator to the poles but the air pressure varies alternately.

Answer the following questions in one to two sentence:

Question 1.
Which factors influence air pressure?
Answer:
The altitude of a region, temperature of the air and the amount of water vapour in the air are some factors influencing air pressure.

Question 2.
What is the extent of air pressure belt?
Answer:
The extent of air pressure belt is generally upto 10° parallel.

Question 3.
What is the latitudinal extent of temperate zone?
Answer:
The latitudinal extent of temperate zone is from 23°30’N to 66°30’N and 23° 30’S to 66° 30’S.

Question 4.
What is the temperature in the polar region?
Answer:
In both the polar regions, the temperature is below 0°C throughout the year.

Question 5.
Why do all things in and on the earth stay earth bound?
Answer:
All things in and on the earth stay bound due to the earth’s gravity.

Question 6.
Why are temperature zones created on the surface of the earth?
Answer:
The heat received from the sun is uneven in different regions. Hence the distribution of the temperature is uneven from the equator to the poles. As a result, temperature zones are created.

Question 7.
Most of the hot deserts on the earth are found in which region?
Answer:
Most of the hot deserts on the earth are found in the mid latitudinal high pressure belt ie; between 25° to 30° parallels in both hemispheres.

Give reasons:

Question 1.
Air pressure is maximum at sea level.
Answer:

• All things in and on the earth stay earthbound because of the earth’s gravity. This includes air which is in the gaseous form.
• Due to the earth’s gravity, air is pulled to the earth’s surface.
• Also as one moves higher & higher from the earth’s surface the air becomes thinner & thinner.
• Therefore, the air pressure is maximum at sea- level.

Question 2.
A low pressure belt is formed near the equator.
Answer:

• The sunrays can be perpendicular between the Tropic of Cancer and the Tropic of Capricorn.
• The temperature is higher in this region.
• Hence air in this region gets heated, expands and becomes lighter and moves towards the sky.
• As this process operates continuously, a low pressure belt gets formed in the central part of this region between the parallels 5° N and 5° S, near the equator.

Question 3.
High pressure belt is formed near the polar region.
Answer:

• In both the polar regions, the temperature is below 0° throughout the year.
• The air is cold.
• Hence, high pressure belt is formed in the polar region.

Question 4.
Low pressure belt is observed between 55° and 65° parallels in both the hemispheres.
Answer:

• Due to the earth’s curvature, the area between two parallels gets reduced as we move towards the poles. This results in lesser friction of the air with the earth’s surface.
• The air between 55° and 65° parallels is thrown out because of the reduced friction and also due to the earth’s rotation.
• Therefore, a low pressure belt is observed between 55° and 65° parallels in both the hemispheres.

Question 5.
Temperature and air pressure are closely related.
Answer:

• Wherever the temperature is high, the air pressure is low. As the temperature rises the air gets heated, expands, and become lighter.
• Thin, lighter air in the vicinity3 of the earth’s surface starts moving up towards the sky. As a result the air pressure in such area decreases.
• Hence, temperature and air pressure are closely related.

Question 6.
Most of the hot deserts on the earth are found in mid-latitudinal high pressure belts.
Answer:

• The air in mid-latitudinal high pressure belt (between 25° to 35° parallels in both hemisphere) is found to be dry.
• The amount of water vapour is very low & hence this region gets extremely scarce or no rainfall.
• Consequently, most of the hot deserts on the earth are found in mid latitudinal high pressure belts.

Give short answers to the following questions:

Question 1.
What are the effects of air pressure?
Answer:
Air pressure has the following effects.

• Origin of winds.
• Generation of storms
• Convectional type of rain.

Question 2.
What is the difference between the temperature zones and pressure belts?
Answer:
(i) The difference between the temperature zones & pressure belts is that the latitudinal extent of temperature zones is much larger while pressure belts are narrower.

(ii) For example, the Temperate zone extends from 23°30′ to 66°30′ in both hemisphere. Compared to this the pressure belt has limited extent which is generally upto 10° parallel.

(iii) Also the temperature zones are continuous & spread from the equator to the poles from Torrid to Frigid.

(iv) Pressure belts are not continuous & areas of high & low pressure are found in different regions from the equator to the poles.

Question 3.
How does a high pressure belt get formed near 30° parallel? Why does this region have hot deserts?
Answer:
(i) The heated air from the equatorial region becomes lighter, starts ascending and after reaching higher altitudes, moves towards the polar region, i.e., towards the North and the South Pole.

(ii) Due to low temperatures at the higher altitudes, the air cools down and becomes heavier. This heavier air descends down in both the hemispheres in the region between 25° to 35° parallels.

(iii) This leads to the formation of high pressures belts in these parallels of latitudes in both the hemispheres.

(iv) This air is dry, hence the region does not get rainfall. Consequently, most of the hot deserts on the earth are found in these regions.

Think about it:

Question 1.
What will be the effect on air pressure if the temperature drops? Why?
Answer:
If the temperature drops, the air pressure will increase as the air becomes heavy.

State whether the following statements are true or false with reasons:

Question 1.
Human rights are necessary for living as a human being.
Answer:
True.
The concept of human rights has emerged from the concept of natural rights. Natural rights are those rights that we are endowed with because we are bom as human beings. In the same vein, human rights are those rights that are necessary for living as a human being.

Question 2.
The scope of human rights is limited.
Answer:
False.
The scope of human rights has in fact, broadened due to several issues of global nature like contagious diseases, the threat to environment, natural disasters, etc. Human rights today also include goals like protection of the environment and sustainable development.

Question 3.
Only internal security is threatened due to terrorist attacks.
Answer:
False.
The aim of a terrorist attack is not to endanger the geographical boundaries, but to challenge a regime in a country or refuse to acknowledge the existence of the State. This means that due to increasing terrorism, the internal security of a country is threatened in addition to its external security.

Question 4.
Once the refugees reach a safe place, they have new challenges.
Answer:
True.
Once the refugees reach a safe place, they need to find work, a place to live and other problems of a day to day nature. If the language and culture in the other nation are different, then adjusting to that poses difficulties. There is also no assurance that the people of a nation which gives shelter to the refugees will accept them.

Explain the concept:

Question 1.
Human Rights
Answer:
The concept of human rights has emerged from the concept of natural rights. Natural rights are those rights that we are endowed with because we are born as human beings. Human rights are those rights that are necessary for living as a human being and as a constituent of society.

Question 2.
Refugees
Answer:
People who have to leave their motherland against their wishes or are forced to go to other nations, seeking refuge or for security are called as refugees. People become refugees due to torture or persecution for belonging to a particular race or religion, due to war or a disaster, etc. In such situations people are forced to leave their own country and seek shelter in another country.

Question 3.
Terrorism
Answer:
Terrorism is spreading fear and terror in a society by using or threatening to use violence against common and innocent people for achieving political goals. Terrorism can be described as organised and planned violence.

Question 4.

Answer:
Wrong Pair: Dr Mohan Rao – polio

3. Explain the concepts:

Question 1.
The institution of the family.
Answer:
The institution of family can be explained as follows:

• During the pre-independence period, the institution of the family was an important identifying feature of Indian society.
• India was known all over the world as the country of joint families.
• However, the wave of globalisation has now given an impetus to the system of nuclear families.

Question 2.
Jaipur Foot technology
Answer:
(i) Dr Pramod Sethi designed and manufactured artificial limbs, noses and ears, with the help of the skilled craftsman Ramchandra Sharma.

(ii) These artificial body parts manufactured with the help of the Jaipur foot technology have made it easy for the differently-abled to walk bare-foot on rough surfaces, run, go cycling, work in the fields, climb trees, and even climb mountains, etc.

Question 3.
Urbanization
Answer:
(i) Urbanisation is a process of the concentration of population in a city or urban area. Increasing population is one major reason for urbanisation.

(ii) A few other factors affecting urbanisation are air, water and the economic as well as social organisations necessary for community life.

(iii) In the context of post-independence India, the increase in urban population is also due to factors such as a reduction in the mortality rate, industrialisation, unavailability of means of livelihood in rural areas, job opportunities in cities and the resulting migration.

Question 4.
Changing economic life
Answer:
(i) Earlier, every village was economically self-sufficient. A majority of the villagers were dependent on farming. Farm produce used to be distributed among artisans as payment for their work.
(ii) Now this situation has changed. Rural areas are engaged in agriculture and occupations ancillary to farming while urban society is engaged in non-agricultural production and the service sector.

4. Give reasons:

Question 1.
The campaign for pulse polio immunisation was initiated.
Answer:
The campaign of pulse polio immunisation was initiated because:

• Before 1978, every year, six Indian infants out of every 10 who were bom faced fatal health problems in the very first year of their birth.
• The immunisation programme was taken up to overcome the threat of polio, measles, tetanus, TB, diphtheria, and whooping cough.
• The ‘pulse polio’ immunisation programme started in 1995 has controlled polio.

Question 2.
The Rural Water Supply Scheme was started.
Answer:
The State started the Rural Water Supply Scheme for sinking wells and providing piped water because:

(i) It is necessary to give priority to facilities for public hygiene and health-care. However even today, the rural population faces problems related to year-round provision of drinking water, toilets, open drainage, narrow roads, inadequate electrification and lack of facilities for medical treatment.

(ii) There is a lack of good quality educational facilities from primary level to higher education, centres for recreation and libraries.

(iii) The collective development scheme had an important place in all the first four five year plans of the government of India. The State of Maharashtra registered remarkable achievements under this scheme. By 1971,1677 small dams had also been built.

5. Answer the following questions in 25-30 words:

Question 1.
Which kinds of discrimination does the Constitution prohibit?
Answer:
(i) According to our Constitution, all Indians are equal before the law, and they cannot be discriminated against on the basis of religion, race, caste, gender or place of birth.

(ii) All citizens have the right to freedom of speech and expression, freedom to assemble peacefully without arms, freedom to form associations, freedom to move, to live and settle down anywhere on Indian territory and to practice any occupation.

(iii) Indian citizens living anywhere in India enjoy the right to nurture their language, script and culture.

Question 2.
What is the aim of the social welfare programme?
Answer:
(i) The objective to establish the welfare state has been incorporated in the Constitution itself.

(ii) The social welfare programmes aim to make opportunities for full-time employment, health care, education and development available to all Indian citizens. Indian society is riddled with large scale economic, social, educational and cultural inequalities.

(iii) However, it is necessary that opportunities for development reach women, children, the differently-abled, the scheduled castes and tribes as well as other minorities.

(iv) Hence on 14th June 1964, the government of India constituted the Ministry of Social Welfare. Under this ministry, various programmes are implemented for nutrition and child- development, social security and social protection, women’s welfare and development.

Question 3.
What are the challenges facing rural development?
Answer:

(i) In 1961, 82% of India’s population resided in villages. In 1971, the percentage was 80.01%.
(ii) So far, the rural area has shouldered the responsibility of providing food grains and other raw material to urban areas, supplying labour to the industrial sectors of the city, and taking care of natural resources.
(iii) However there are three major challenges with reference to rural development, namely, bringing about economic development, developing facilities to meet social needs and finally bringing about a change of attitude in matters concerning society, culture and ways of thinking.
(iv) It is also equally necessary to expedite irrigation projects and bring about land reforms.

6. Write a brief review of the significant events in the field of public health in India.
Answer:
The Constitution of India states that the primary duty of the government is to raise the people’s standard of living, to ensure proper nutrition and to improve public health. The Ministry of Health and Social Welfare at the Centre helps the state governments in this regard.

(i) To make primary health services as well as medical care available to rural people, the tribals and the poor was an objective of the Sixth Five Year plan. Efforts were made towards helping people maintain good health by giving recognition to Unani, Homoeopathy, Ayurveda and Naturopathy in addition to Allopathy.
