(3) Freeze thaw weathering	(3) Oxidation	(3) Slide	(3) Slope
(4) Shattering	(4) Carbonation	(4) Flow	(4) Rainfall

Answer:
C

4. Give geographical reasons.

Question 1.
Temperature is the main factor behind granular weathering.
Answer:
Temperature is the main factor behind granular weathering because-

1. In hot desert areas, diurnal range of temperature is high.
2. As the temperature increases with the rising sun, the rock gets heated and cools down with the decrease in temperature.
3. The minerals in the rock react differently to the temperature increase due to continuous heating and cooling.
4. Consequently, it leads to development of stress within the rock and molecular or granular disintegration takes place.

Question 2.
Human is an agent of weathering.
Answer:
Human is an agent of weathering because-

1. Man is a biological agent of weathering. Due to economic and technological development, man has become the most powerful agent of weathering and erosion.
2. Mining, blasting of hills and ridges for road and dam construction, quarrying for industrial and building materials, etc., results in a fast rate of disintegration of rocks.
3. Man accelerates the rate of weathering on hill slopes through activities like deforestation.

Question 3.
Slope is a major factor in mass wasting.
Answer:
Slope is a major factor in mass wasting because-

1. Mass wasting is the down-slope movement of loose mixture of soil, land and rock particles by the force of gravity.
2. In mass wasting the materials come down the slope without the aid of transporting medium like running water, ice or wind.
3. Mass wasting occurs continuously on all slopes.
4. Some act very slowly, others very suddenly, often with disastrous results.

Question 4.
Oxidation changes the size and colour of the rocks.
Answer:
Oxidation changes the size and colour of the rocks because-

1. Oxygen in the air and water reacts with certain elements in the minerals inside the rock
2. In this process, the minerals in the rock react with the oxygen present in the air or water.
3. Metals, particularly iron and aluminium, commonly oxidize forming iron or aluminium oxides. It is also called rusting.
4. These oxides are larger in volume than in the original rocks.
5. The iron oxides are red in colour and aluminium oxides are yellow.
6. Thus, oxidation changes size and colour of the rock.

Question 5.
Effect of mass movement will be greater along the western slope of the Sahyadri’s than the eastern slope.
Answer:
Effect of the mass movement will be greater along the western slope of the Sahyadri’s than the eastern slope because-

1. The western slope of the Sahyadri’s are steeper than the eastern slopes.
2. The western slopes receive more rainfall than the eastern slopes as a result mass movement is greater in western slopes than eastern slopes.
3. Also, the rivers as an agent of erosion are short and swift on the western slope and thus rapid mass movement is found as compared to eastern coast.

5. Write short notes on.

Question 1.
Gravity and Solifluction
Answer:
Gravity:

1. It is the main force responsible for mass movements.
2. It is a force that acts everywhere on the earth’s surface, pulling everything down.
3. If the friction on the rock is stronger than gravity for a particular slope, the rock material is likely to stay.
4. But if the gravity is stronger, movement will occur in the direction of the slope.

Solifluction:

1. Solifluction is the name for the slow downhill creep of soil, which occurs in a variety of climatic conditions.
2. It occurs in periglacial or alpine regions.
3. As permafrost is impermeable to water, soil overlying may become oversaturated and slide slopes down under the pull of gravity.

Question 2.
Role of water in mass wasting
Answer:

1. Although water is not always directly involved as a transporting medium but it plays an important role in mass wasting.
2. Addition of water from rainfall or snowfall or melting of snow makes the material on the slope heavier.
3. Water can reduce the friction along a sliding surface.

Question 3.
Exfoliation
Answer:

1. Because of the overlying rocks, the rocks beneath the surface experience a lot of pressure.
2. The exposed part of the rock heats more while the inner part is comparatively cooler.
3. As a result, the outer layer of the rocks fall apart from the main rock just as we peel off onion.

Question 4.
Weathering and homogeneity in rocks
Answer:

1. Weathering is the physical or chemical breakdown of rocks into small pieces due to various reasons like weather conditions, temperature, and water, living organisms like humans, algae, fungi, etc.
2. Weathering depend upon the texture of the rock. Those rocks which have joints on layers break easily than rocks which are homogeneous. Generally, sedimentary rocks break easily than igneous rocks as sedimentary rocks are formed by layering.
3. Sediments brought down by the river are deposited in layers, thus sedimentary rocks are soft and porous, and can be broken easily.
4. Igneous rocks are formed by cooling and solidification of molten magma. Hence, they are hard and non-porous and cannot be broken so easily.
5. Thus, sedimentary rocks are more subjected to weathering than the igneous rocks.

Question 5.
Carbonation
Answer:

1. The decomposition of dead matter in the soil produces CO₂
2. This CO₂ and the CO₂ in the air reacts with minerals in the rocks.
3. Minerals such as feldspar and carbonates decompose when this happens.
4. In humid climate, water adds to the weathering process.
5. In arid climates, the absence of water in the region leads to carbonate rocks to form cliffs that are resistant.
6. Often, carbonation and solution occur simultaneously.
7. During carbonation, the calcium and carbonate in limestone detach from each other, thereby decomposing the limestone.

6. Draw a neat and labelled diagram for

Question 3.
Biological Weathering
Answer:

7. Answer in detail.

Question 1.
Explain with examples the process of weathering happening in Konkan.
Answer:

1. Konkan, also known as the Konkan Coast is a rugged, section of the western coastline of India.
2. The region is divided into North Konkan including Mumbai, Thane and Raigad districts whereas South Konkan include Ratnagiri and Sindhudurg districts.
3. Laterite rocks-occur in the form of plateaus at Konkan strip. High altitude laterite plateaus
   are found is Sitara, Kolhapur, Ratnagiri and Sindhudurg district.
4. In the laterite rocks soft silica matter is present.
5. Because of high rainfall exposed rocks become empty to wash out of soft silica matter.
6. Laterite soil is formed by laterite rock in high elevation. The soil contains has high concentration of ferrous and aluminium. This soil is very stony because of the presence of weathering fragments of iron concentrations.
7. Oxygen in the air and water reacts with certain elements in the minerals in the rock. The metals in the rock particularly iron and aluminium oxidise and form iron and aluminium oxides. Thus, chemical weathering takes place.
8. Laterite soil is found in Mahabaleshwar, Southern parts of Mahabaleshwar, around Bhima Shankar and Matheran. Thus, chemical and mechanical weathering is found.

Question 2.
Explain the correlation between Himalayas and mass movements. Give examples wherever necessary.
Answer:

1. Mass movements occur in hilly, mountainous or plateau areas. The steeper the slope more the occurrences of mass movement.
2. The Himalayas have greatest relief, high potential energy, high seismic activity, steep slopes, strong weathering, great snow fall etc.
3. Due to slope, gradient, massive rockslides, debris flow takes place.
4. Steep gradient of precipitation and temperature produce mass movement that loads glacier surface and chokes, rivers with sediments.
5. For example, in Kosi river basin of Himalayas of central Nepal, because of deep weathering, high seismic activity, river undercutting, deforestation and heavy precipitation, especially during the summer months, mass movements are most frequent in highly jointed, sheared, intensely folded and fault rocks.
6. Thus, in short, in the Himalayan region, due to steep slope, melting of glaciers, precipitation, seismic activity, mass movement takes place on a larger scale.

11th Geography Digest Chapter 2 Weathering and Mass Wasting Intext Questions and Answers

Let’s recall (Textbook Page No. 15)

1. Study the diagram in fig 2.1 and answer the following questions.

Question 1.
Identify the types of rocks shown in the diagram.
Answer:
Igneous, sedimentary and metamorphic rocks are shown in the diagram.

Question 2.
Arrange the rocks according to their chronology of origin.
Answer:
Igneous, sedimentary and metamorphic rocks.

Question 3.
Explain how sedimentary rocks are formed.
Answer:
Sedimentary rocks are formed from layering upon layering of all the organic (dead remains of plants and animals) and in organic (sand, silt, clay, gravel, etc.) material in a depression or on low lying area. If there are cementing material like limestone, hardening and compaction takes place, then sedimentary rocks are formed.

Question 4.
Think of all the factors which may break the rocks into smaller pieces.
Answer:
Heat, pressure, water, wind, animals, plants etc., can break rocks into smaller pieces.

Question 5.
Which type of rock will break easily as compared to others? Why?
Answer:

1. Sedimentary rocks will break easily as they are formed by layering of sediments and thus, they are soft and porous and are broken easily.
2. Igneous rocks are formed from cooling and solidification of molten magma; hence they are hard and non- porous.
3. The metamorphic rocks too cannot be broken easily as they are formed from heat and pressure.

Think about it.

Question 1.
In which regions will freeze-thaw weathering not be effective? (Textbook Page No. 17)
Answer:
Freeze-thaw weathering will not be effective on the cold polar regions as the soil cover and rocks are very little on the polar areas and moreover, there is snow everywhere.

Question 2.
Besides climatic factors, rock type and structure, can you think of some more factors that affect weathering? (Textbook Page No. 19)
Answer:
Plants, animals, micro-organisms, humans are some more factors that affect weathering.

Question 3.
Can tectonic forces be responsible for mass movement? (Textbook Page No. 25)
Answer:

1. Plate tectonics are responsible for uplift and mountain building that creates and maintains slopes.
2. Mass wasting is common in tectonically active regions.
3. Plate tectonics causes earthquakes that can trigger landslides and cause sediment to lose its strength through liquefaction.

Question 4.
There is a shift of materials in mass movement as well as in transportation from one place to the other. So, why can’t both not be treated as one and the same? (Textbook Page No. 25)
Answer:
Mass movement is caused by abrupt movement and freefall of loosened rock particles because of gravity and friction falling towards the surface, whereas transportation is carrying of rock materials with the help of agents of erosion such as water, wind, air, ice, etc. Thus, they are not same.

Use your brain power!

Question 1.
Can animals and plants also influence weathering? Will that be physical or chemical weathering? Which type of weathering does stone quarrying cause? (Textbook Page No. 19)
Answer:
Yes, burrowing animals widen the fissures in the rocks. Rocks become weak and disintegrate.

The roots of the trees and other plants penetrate in the soil, they grow in size, exert pressure on rocks, widen cracks in the rocks and rocks break. Many microscopic organisms such as algae, lichens, bacteria, moss etc produce chemicals and they break down the outer layer of the rock. These chemicals are responsible for physical and chemical weathering of rocks. The stone quarrying causes the anthropogenic weathering.

2. A region is having an annual mean temperature of 5° C and an annual rainfall of 1000 mm. Can you comment upon the weathering and the type with the help of following questions? (Textbook Page No. 20)

Question 1.

Answer:
Rock layer C has experienced the most weathering.

Question 2.
Which rock layer has experienced the least weathering?
Answer:
Rock layer B has experienced the least weathering.

Question 3.
What could be the reason behind difference in weathering?
Answer:
Rock C has lot of fractures and joints so it got weathered easily.
Rock B might have been a hard rock, more resistant, so weathering process is slow.

2. The satellite images given in fig. 2.11 A and B belong to the same location but different timeline. Study the images and answer the following questions. (Textbook Page No. 21)

Question 1.
Compare the images and tell what differences do you find in these images?
Answer:
Image 2.11 (A) shows maximum area under vegetation. Image 2.11 (B) shows development in form of settlements and transportation routes.

Question 2.
In 2019, what does the patch of land going from north-west to south-east signify? Why was it not there in 2011 image?
Answer:
The sweeping portion from north-west to south-east is visible in satellite image of 2019. This is because the village is located at the foothills. The rain and slope were responsible for the mudslide. Heavy rainfall and absence of vegetation aggravated the situation. In 2011, vegetation was thick but in 2019 deforestation has been done extensively for farming practices.

Question 3.
To what extent is the climate of a place responsible for this disaster?
Answer:
Climate plays an important role for the disaster. Heavy rainfall makes soil to move from the surface of the mountain towards the foothills.

Question 4.
Which other factors are responsible for the disaster?
Answer:
Deforestation and absence of vegetation are responsible for this.

Answer:
Table

Think a little. (Textbook Page No. 24)

Think of the reason why landslides should be more frequent in foothill zone of the Himalayas and Western Ghats region. Why do landslides not occur in Marathwada in Maharashtra or Maidan area in Karnataka?
Answer:
Himalayas are one of the youngest fold mountains of the world. They are formed due to convergent movement of the Indian plate and erosion plate. They are still rising in height. These tectonic movements cause frequent earthquakes in the region resulting into landslides whereas western Ghats lie in the stable Deccan shield less prone to landslides.

Himalayas are greater in height than the western Ghats. The slopes are comparatively steep and hence landslides are common in Himalayas whereas, the western Ghats are much lesser in height than the Himalayas hence less prone to landslides as compared to Himalayas.

The perennial rivers in Himalayas carry lots of sediments during rainfall and due to melting of glaciers in the summer thus leading to landslides, whereas, in Western Ghats many rivers are non-perennial and hence less amount of silt and debris in carried as compared to Himalayan rivers. Thus, there is reduction in the chances of landslides, only during the rainy season, landslides occur in Western Ghats region.

Try this. (Textbook Page No. 24)

Question 1.
Different types of materials flow down the slope. Types of mass wasting depend on their speed. Observe the pictures given in figure 2.12. Match the explanation given below with the diagrams. Identify them as slow or rapid movements.

Answer:

Answer:
C

4. Give geographical reasons.

Question 1.
Extinct conical volcanoes often form crater lakes.
Answer:
Extinct conical volcanoes often form crater lakes because-

1. An extinct volcano had no volcanic eruption for at least 10,000 years and is not expected to erupt again in future.
2. After the eruption a large and deep depression remains in that area. Smaller depressions are called craters.
3. This crater eventually gets filled with water and crater lakes are formed.
4. The water may come from precipitation, ground water circulation or melted ice.

Question 2.
People living in the Himalayas are more vulnerable to earthquakes.
Answer:
People living in the Himalayas are more vulnerable to earthquakes because-

1. Himalayan mountain ranges are formed as a result of collision of Indo-Australian plate and Eurasian plate.
2. According to plate tectonic theory, Indo-Australian plate (on which India lies) is moving towards north and is subducting under Eurasian plate.
3. This movement obviously cause friction between two plates.
4. Thus, these regions are more prone to earthquakes.

Question 3.
L-waves do not have a shadow zone.
Answer:
L-waves do not have a shadow zone because-

1. The shadow zone is the area of the earth from angular distance of 105° to 140° from a given earthquake for both P-waves as well as S-waves.
2. Generally, seismographs located at any distance withinl05° from epicentre record the arrival of S-waves and beyond 140° from epicentre record the arrival of P-waves.
3. L-waves are typically generated when the source of the earthquake is close to the earth’s surface.

Question 4.
Soft rocks form folds while hard rocks form faults.
Answer:
Soft rocks form folds while hard rocks form faults because –

1. Soft and elastic rocks are affected by compressional forces.
2. Rocks that lie deep within the crust and are therefore under high pressure are generally ductile and particularly susceptible to folding without breaking.
3. Whereas rock layers that are near the earth’s surface are too rigid to bend into folds.
4. If the tectonic force is large enough, these rocks will break rather than bend and faulting on rupture occur.

Question 5.
Folds depend on the strength of rocks and intensity of forces.
Answer:
Folds depend on the strength of rocks and intensity of forces because-

1. The elasticity of rocks largely affects the nature and magnitude of folding process.
2. The softer and more elastic rocks are subjected to intense folding while rigid and less elastic rocks are only moderately folded.
3. The compressional forces push two portions of the crustal rocks together and tend to shorten and thicken the crust.
4. Rocks that lie deep within the crust and are therefore under high pressure are generally ductile and particularly, susceptible to folding without breaking

5. Answer in detail.

Question 1.
Explain different types of faults.
Answer:
A fault is a fracture in the crustal rock, formed when the crustal rocks are displaced due to tensional movement caused by endogenic forces. The displacement of rock can occur in upward, downward or horizontal direction.
The different types of faults determined by the direction of motion are:
Normal fault: It results when a portion of land slide down along the fault plane and when the exposed portion of the plane faces the sky

Reverse fault: It results when a portion of the land is thrown upward relative to other side of the land. In such situation, the fault plane faces the ground.

Tear fault: At times, the rock strata on either side of the fault plane do not have vertical displacement. Instead, movement occurs along the plane in horizontal direction.

Thrust fault: When the portion of the land on one side of the fault plane gets detached and moves over the land on the other side. The angle of fault plane is generally less than 45°.

Question 2.
Explain with examples, different types of landforms produced by volcanic eruption.
Answer:
A number of landforms are formed due to cooling and solidification of magma. Some important landforms are:
Lava domes:

1. Domes are developed when magma comes out and solidifies around its mouth.
2. The shape of the dome depends upon the fluidity of lava.
3. High dome with steep slopes is developed by acidic lava.
4. Due to basic lava, broad – based low domes are developed.

Lava plateaus:

1. Due to spread of lava in huge quantity from fissure volcano, it covers large areas and plateaus are formed.
2. The Deccan Trap in India has developed from volcanic eruptions millions of years ago.

Caldera:

1. At times, the eruption of volcano brings about large quantity of material and relieves lot of pressure.
2. After the eruption, a large and deep depression remains in that area. This large depression is called caldera.
3. These can be around 10 km wide and hundreds of metres deep.
4. They may later turn into lakes. Smaller calderas are known as craters.

Crater lake:
When the funnel shaped crater of an extinct volcano gets filled with rain water, it forms a crater lake.

Volcanic plug:

1. It is formed when the lava solidifies in the volcanic neck.
2. The surrounding rock material is removed by different agents of erosion; the vent stands predominantly. It is called as volcanic plug.
3. The diameter of a plug varies between 300 and 600 metres.
4. The Devil’s Tower in Wyoming, United States of America is the best example.

Cinder cone:

1. Solid material is ejected in large quantity.
2. This material consists of ash, cinder and breccias.
3. Cinders are half burnt pieces of solid material.
4. The solid material is deposited around the mouth until a conical hill with steep slopes is formed.
5. For example, cone of Mt. Nuovo in Italy.

Composite cone:

1. Composite cones are built up of alternate layers of lave and cinder.
2. This cone is composed of two materials and therefore it is called a composite cone.
3. It is symmetrical in shape.
4. For example, Mt. St. Helens, USA.

Question 3.
Explain the concept of shadow zone.
Answer:

1. The waves which are caused by earthquake are called seismic waves. There are three types of waves: P-waves, S-waves and longitudinal waves.
2. P-waves can pass through all the mediums while S-wave can pass only through solid medium.
3. Even though P-waves pass through all mediums, they experience refraction as they pass from one medium to the other.
4. However, there exist some specific areas where the waves of that earthquake are not reported. Such zone is called ‘shadow zone’.
5. Generally, seismographs located at any distance within 105° from the epicentre, record both P-waves and S-wave. However, beyond 140° P-wave are recorded but not S-waves.
6. Thus, the zone between 105° and 140° is identified as the shadow zone for both types of waves.
7. The entire zone beyond 105° does not receive S-waves. The shadow zone of S-waves is much larger than that of P-waves.
8. The shadow zone of P-waves appears as a band round the earth between 105° and 140° away from the epicentre.

Question 4.
Write a note on volcanic materials.
Answer:
There are three main types of material which come out in volcanic eruptions namely liquid, solid and gaseous form.
Liquid material:

1. It is the molten rock material. When the molten rock material is below the earth’s surface, it is called ‘Magma’.
2. When it appears on the surface it is called ‘lava’. On the basic of percentage of silica, it is classified as:
3. Acidic lava : (a) It contains higher percentage of silica, (b) It has high melting point, (c) It is thick, fluid and moves slowly.

6. Differentiate between.

Question 1.
Folding and Faulting.
Answer:

Folding	Faulting
(i) Folds are bends in the rocks that are due to compressional forces.	(i) Faults are formed due to tensional forces along which displacement of rock takes place.
(ii) Folding occurs when compressional forces are applied to rocks that are ductile or flexible.	(ii) Faults occurs when force operating in opposite direction lead to tension and as a result rocks develops cracks on fissure.
(iii) Rocks that lie deep within the crust and are therefore under high pressure are generally ductile and particularly susceptible to folding without breaking.	(iii) Rock layers that are near the earth’s surface and not under high confining pressures are too rigid to bend into folds, but if tectonic forces are large, rocks break.
(iv) Folding leads to development of fold mountain. For e.g., the Himalayas, the Alps, etc.	(iv) Faulting results in the formation of block mountains like black forest mountain etc., and right valleys like the Narmada, Tapi, etc.

Question 2.
Normal fault and Reverse fault.
Answer:

Normal fault	Reverse fault
(i) It results when a portion of landslides down along the fault plane.	(i) It results when a portion of land is thrown upward relative to other side of the land.
(ii) The exposed portion of plane faces the sky.	(ii) The fault plane faces the ground.

Question 3.
Syncline and Anticline.
Answer:

Syncline	Anticline
(i) As and when limbs slopes towards each other and the central part located at lower elevation forms synclines.	(i) As and when limbs slopes downward with central position getting raised up, it is called anticline.
(ii) They form valleys.	(ii) They form the top / peak of the mountain.
(iii) They have a greater depth.	(iii) They are of a greater height.

Question 4.
Asymmetrical fold and Symmetrical fold.
Answer:

Asymmetrical fold	Symmetrical fold
(i) The axial plane is inclined.	(i) The axial plane is vertical.
(ii) Limbs are inclined at different angles.	(ii) Limbs are inclined at same angles.
(iii) The height and shape of limbs is not same.	(iii) The height and shape of limbs is same.

Question 5.
Mercalli scale and Richter scale.
Answer:

Mercalli scale	Richter scale
(i) It measures the intensity of earthquake.	(i) It measures the energy released during an earthquake.
(ii) The measurement is based on observed effects.	(ii) The measurement is done with the help of seismograph.
(iii) Quantified from observation of the effects on earth’s surface, human beings, objects and man- made structures.	(iii) Quantified from logarithmic scale obtained by calculating logarithm of the amplitude of waves.
(iv) Unit of measurement I (not felt) to XII (total destruction)	(iv) Unit of measurement from <2.0 to 10.0 + (never recorded) 3.0 earthquake releases 32 times more energy than a 2.0 earthquake.

Question 6.
Slow movements and Sudden movements.
Answer:

Slow movements	Sudden movements
(i) Slow movement include both vertical and horizontal movement which are caused due to forces deep within the earth.	(i) Sudden movements are caused by sudden endogenic forces coming from deep within the earth.
(ii) These movements are occurring continuously.	(ii) These movement occurs in the form of events.
(iii) Slow movements include formation of mountains and continents.	(iii) Sudden movements include event such as earthquakes and volcanoes.

1. Observe the following pictures in fig 1.1 and discuss the questions.

Question 1.
What might be the reasons behind buildings collapsing in photo 1?
Answer:
The major reason behind the buildings collapsing in photo 1 is the occurrence of earthquakes.

Question 2.
Which event in depicted in photo 2? What impact does it bring about in the surroundings?
Answer:
The volcanic eruption and flowing of lava is depicted in photo 2. Heavy loss of life and property is experienced when the lava flows to the surrounding area.

Question 3.
In photo 3, what could be the reason behind the bend in the rock strata?
Answer:
Due to compression of sediments within the earth’s interior and pressure from overlying layers the rock strata seems to be bended.

Question 4.
What could be the reason behind the difference in altitudes of the land and the steepness of the slope in photo 4?
Answer:
The reason could be displacement of rock due to vertical movement. It may form plateau on block mountains.

Question 5.
Classify the events in the photos into sudden and slow movements.
Answer:
Sudden movements are earthquake and volcanoes in photo 1 and 2. Slow movements are formation of folds and formation of plateaus or block mountains in photo 3 and 4.

Question 6.
Example of which of these movements is not likely to be found in the mainland of Indian sub- continent?
Answer:
The volcanic eruptions are not found in mainland of India sub-continent.

A very high intensity earthquake struck north eastern parts of Indonesian coastline, where subsequent landslides into sea triggered tsunamis.

Question 3.
Name the energy waves involved in this natural event.
Answer:
Tsunamis were involved in this natural event where the tectonic plates moved horizontally.

Question 4.
Observe the diagram in fig. 1.9 and label the boxes.

Answer:

Think about it.

Question 1.
How will compressional forces affect brittle rocks? (Textbook Page No. 3)
Answer:
The compressional forces will break the brittle rocks into pieces.

Question 2.
A mountain never remains a mountain’. Can you relate this idiom with the mountain building process? (Textbook Page No. 4)
Answer:
This happens because of continuous erosional activities taking place on the mountain sides. Running water glaciers, wind, volcanic activities keep on changing the surface of a mountain.

Question 3.
When can faults form is fold mountains? (Textbook Page No. 6)
Answer:
If compression takes place along the faults, folds can be formed.

Question 4.
Can folds form into block mountains? Find the reason and discuss. (Textbook Page No. 6)
Answer:
No, folds cannot form into block mountains because folding takes place due to compression of elastic rocks and block mountains are formed due to displacement of rocks owing to tension.

Question 5.
Look at fig.1.10 and answer following questions. During an earthquake, do you think the seismic waves reach entire portion of the earth. Is there any region on the earth’s surface where a given earthquake will not be reported? (Textbook Page No. 6)
Answer:
It’s the shadow zone of P-waves and S-waves where the seismic waves do not reach. No there is no region on the earth’s surface where a given earthquake is not reported.

Question 6.
Why has the shadow zone for L-waves not been shown in fig 1.10? (Textbook Page No. 7)
Answer:
L-waves travel through the circumference of the earth. Thus, they do not been form shadow zone.

Can you tell? (Textbook Page No. 7)

In fig 1.10 textbook page 6 A, B, C are three points on the earth’s surface. Analyse their location with respect to epicentre and shadow zones
Answer:
A, B, C are the points on the surface of the earth.
(i) ‘A’ point is located with 105° from the epicentre, therefore P waves and S waves reach at ‘A’ point. The seismograph at !A’ point records both waves, therefore ‘A’ point is not in shadow zone.

(ii) ‘B’ point is in shadow zone because both the waves do not reach there. P waves pass through all mediums, they experience refraction as they pass on one medium to another. The seismograph records P waves, which is located away from ‘B’ point. But P waves are not recorded in an area between 105 and 140° from epicentre. The S waves also do not reach here. Therefore, it is called ‘Shadow zone’ of Earthquake waves.

(iii) ‘C’ point is in the area of the shadow zone of ‘S’ waves, that in within 140°. P waves reach beyond 140°. Since ‘S’ waves do not reach here, it is called ‘Shadow zone of S waves’.

Read the following passage about Krakatoa volcanic eruption and answer the following questions. (Textbook Page No. 10)

There is an island known as Krakatoa between the islands of Java and Su matra in Indonesia. There were frequent volcanic eruptions here. From May 1883, massive explosions began. The eruption that took place at about 10 in the morning on 28 August 1883 was the largest ever recorded explosion. As a result of this explosion, the entire island disappeared. During this eruption, rock particles and dust thrown up in the atmosphere was about 25 km³. The column of this dust-ash rose as high as 80 km.

The discharge of Krakatoa threw into the air nearly 21 km3 of rock fragments, and large quantities of ash fell over an area of some 800,000 km². Near the volcano, masses of floating pumice, were so thick that ships had to halt. The surrounding region was plunged into darkness for two and a half days because of ash in the air. For some years after this, cloud kept moving round the earth. About 36,000 people died in these eruptions and the tsunami waves created by it.

In 1927, volcanic eruptions began at the same place and a new island rose in place of the Krakatoa island that had vanished. It was named Anak Krakatoa’ or ‘Child Krakatoa’. The volcano here constantly emits ash and steam. This new island has now become a laboratory for geologists and biologists.

Question 1.
Make a list of materials that came out during eruptions.
Answer:
Rock, particles, dust, ash, floating pumice, steam were the materials that came out during eruption.

Question 2.
Classify them into liquid, solid and gaseous forms.
Answer:

Liquid	Solid	Gaseous
Pumice	Rock particles	Steam
	Dust
	Ash

Find out! (Textbook Page No. 9)

Find out examples of active, dormant and extinct volcanoes.
Answer:
Examples of active volcanoes are – Mt. Etna (Italy), Stromboli (Italy), Mt. Merapi (Indonesia), Erta Ale (Ethiopia), Mt. Erebus (Antarctica)
Examples of dormant volcanoes – Mt. Kilimanjaro (Africa), Mt. Katmai (Alaska)
Examples of extinct volcanoes – Mt. Egmont (New Zealand), Chimborazo (Ecuador), Mt. Kulal (Kenya)

Give it a try (Textbook Page No. 8)

Take the given hypothetical data in the table. The data shows the time of arrival of P-waves and S-waves at 3 seismograph stations. Assume the scale of the map as 1 cm : 18 km. See fig. 1.11.

Recording Station	P-wave arrival time (IST)	S-wave arrival time
Jalana	11 : 06 : 06	11 : 06 : 19
Washim	11 : 06 : 46	11 : 07 : 03
Aurangabad	11 : 07 : 06	11 : 07 : 24

Answer:
Speed of waves = 08 kms per second
Scale of the map = 1 cm
= 18 kms
First step : Find out the difference in time for waves at Jalana recording centre.
Difference in time of waves = Time of S-wave – Time of P-wave
11 : 06 : 19 (Time of S-wave)
11 : 06 : 06 (Time of P-wave)
= (Time of S-wave) – (Time of P-wave)
= 11 : 06 : 19 – 11 : 06 : 06
= 00 : 00 : 13
Therefore difference in time for waves at Jalana recording centre is 13 seconds.

Second Step : Find out distance on land between Jalana and Epicentre
Distance on land = Difference in time of waves × speed of waves per second
= 13 × 8
= 104
Therefore distance on land between Jalana and Epicentre is 104 km.

Third Step : Find out radius for Jalana Station.
Jalana – Radius of circle = \(\frac {Distance on land}{Scale of the map}\)
= \(\frac {104}{18}\)
= 5.7 cm.
Therefore radius of circle around Jalana station is 5.7 cm.
Now find out radium for remaing stations.
Jalana – 5.7 cm, Washim – 7.5 cm, Aurangabad – 8 cm.

Fouth step : Now draw circles around Jalana, Washim and Aurangad with the help of radius calculated.
All arcs of circle will intersect one another at a particular point. That point is the location of Epicentre.
In the map given below Epicentre is to the south of Mudgal.

4. Answer in short:

Question a.
Differentiate between the forest types of Brazil and India.
Answer:

Forest type of Brazil	Forest type of India
1. The northern part of Brazil lies in the equatorial region. It receives ample sunshine and heavy rainfall. So dense evergreen forests are seen here.	1. The location of India is far away from the Equator. Heavy rainfall occurs only in the Western Ghats and North Eastern hilly areas. So evergreen forests are seen in these regions.
2. The Highland region of Brazil receives low rainfall. So tropical grasslands are seen in this region.	2. The Peninsula region of India receives rainfall between 1000 mm to 2000 mm, so they are covered by deciduous forests.
3. As there are no tall and long extending mountains in Brazil, Himalayan type forests are not found here.	3. Owing to presence of Himalayas, Himalayan type forests are found in North and North-East of India that are classified on the basis of altitude.
4. Thorny shrubs are found to the North Eastern part of Brazilian Highlands which is also considered to be a Drought Quadrilateral.	4. Thorny shrubs are found in India receiving less than 500 mm of rainfall. It is majorly found in Gujarat, Rajasthan and rain shadow regions of the Western Ghats.

Question b.
Correlate wildlife and natural vegetation in India and Brazil.
Answer:
(i) Depending upon favourable geographical conditions, we find a variety of natural vegetation in India and Brazil. Also depending upon the vegetation we find a variety of wildlife in different regions.

(ii) Grasslands of Brazil like the Savannah and the deciduous forest of India have a large number of herbivores and carnivores.

(iii) The dense evergreen forests of India in the west, north east India and the Amazon Basin of Brazil are a home to a large variety of birds, insects, reptiles along with the herbivores and the carnivores.

(iv) Coastal forests and swampy areas of Pantanal and Sunderbans have mangroves, a variety of birds, fishes and reptiles like crocodiles, alligators and the anacondas in Brazil.

(v) Vegetation provides food and shelter to wildlife but if vegetation is limited like in the Thar desert or the Caatinga it will also limit the variety of animals species.

Question c.
What environmental issues are faced by Brazil and India?
Answer:

• Degradation of environment is happening in Brazil due to illegal smuggling of wild animals, slash and burn agriculture (roca), deforestation, pollution, etc.
• Due to these problems, many endemic species are on the verge of extinction.
• India too faces environmental issues such as poaching, pollution and the fast spreading deforestation.
• Many species of wildlife are on the verge of extinction in India.

Question d.
What are the major causes of degradation of forest in Brazil and India?
Answer:
(i) Forests are being cut down as more area is required to expand the cities. Hence rapid urbanisation is one of the reasons for degradation of forest.

(ii) To ensure continuous food supply to meet the needs of the ever increasing population, more and more area needs to be brought under agriculture. For the expansion of agricultural land, forest areas are being cut down.

(iii) In both India and Brazil, forests are being cut down for firewood and for other domestic needs.

(iv) Slash and Burn agriculture which is also known as Roca in Brazil and Jhum in India is responsible for deforestation.

(v) Apart from all the above reasons, forest fire, pollution, overgrazing, etc. are also responsible for the degradation of forests.

Question e.
Why does the deciduous type vegetation occupy most of India?
Answer:

• Vegetation in a region is affected by the climate and rainfall of the region.
• In dia lies in the tropical zone and it has a monsoon type climate throughout the year.
• Also, a major portion of India receives seasonal rainfall between 1000-2000 mm.
• Deciduous forests thrive well in this condition and these forests shed their leaves during the hot and dry summer so that water is not lost due to evaporation.
• Teak, bamboo, banyan, peepal, etc. are the trees found in deciduous forest of India.

5. Give geographical reasons:

Question a.
The northern part of Brazil is covered with dense forests.
Answer:

• The northern part of Brazil lies in the equatorial region.
• It receives ample sunlight and about 2000 mm of rainfall throughout the year.
• In this region, the growth of vegetation is very rapid.
• So, the northern part of Brazil is covered with dense and evergreen forests.

Question b.
Vegetation is scarce in the high altitude of the Himalayas.
Answer:

• As the altitude increases, the temperature decreases.
• The climate is very cold in the high altitudes. In Jammu and Kashmir and parts of Himalayas temperature drops to -40fiC.
• Also this region is snow-covered for most part of the year.
• Very few species of plants can survive in such extreme conditions. Only seasonally flowering trees are found at higher altitudes.
• Hence, vegetation is scarce in the high altitude of the Himalayas.

Question c.
A wide variety of insect species is found in Brazil.
Answer:

• Insects are mostly found in forests, grasslands and swampy lands.
• Many insects eat leaves, grass and nectar from the plant.
• The evergreen rainforests are seen in the northern parts of Brazil. The grasslands are found in the central parts and Paraguay-Parana river basin. Similarly, swampy lands are found in Pantanal region in Brazil. .
• Therefore, a wide variety of insect’s species is found in Brazil.

Question d.
Wild life in India is decreasing day by day.
Answer:
(i) Wildlife in India is decreasing day by day because of rapidly occurring deforestation, poaching, pollution.

(ii) Expansion of cities to accommodate the growing population is leading to cutting down of the valuable forest which leads to the loss of the habitat of wildlife.

(iii) Also the problem of pollution has become severe due to urbanisation. Various types of pollution have threatened the lives of many of the species.

(iv) Poaching of wildlife species have also led to the loss of wildlife in India.

(v) Agricultural practices like shifting cultivation has also reduced the forest cover leading to loss of wildlife habitat.

Question e.
Like India, there is a need for conservation of forests in Brazil too.
Answer:
(i) Like India, Brazil is facing the problem of degradation of environment due to deforestation, pollution, slash and burn agriculture, illegal smuggling of wild animals, etc.

(ii) Trees are being cut down to obtain wood, leading to large scale deforestation in both countries.

(iii) Also the problem of pollution has become severe due to urbanisation. Various types of pollution have threatened the lives of many of the species.

(iv) Agricultural practices like slash and burn agriculture (roca) has reduced the forest cover in Brazil.

(v) Like India, the problem of illegal smuggling of animals has affected Brazil too.

(vi) Hence there is a need for conservation of forests in both Brazil and India.

In India, nucleated human settlements are found in the Ganga River Basin because of flat fertile plains, abundance of water, favourable climate and growth of agriculture and industries. Dispersed settlements are found in Himalayan slopes, eastern and southern Rajasthan because of uneven topography, unfavourable climate and lack of development.

In Brazil, nucleated settlements are found in Sao Paulo and southern coast of Brazil, due to nearness to the ocean, fertile soil, availability of natural minerals like iron ore, steady power supply and good transportation system. Dispersed settlements are found in Northern Brazil due to the inaccessible forests in Amazon river basin, unhealthy climate, limitations on use of natural resources drought region and poor transport connectivity.

The Physiography of India	The Physiography of Brazil
The physiographic divisions of India are the Himalayas, the North Indian Plains and the Peninsula, Coastal Plains, and the Islands.	The physiographic divisions of Brazil are: The Highlands, The Great Escarpment, The Coastal region, The Plains and The Islands.
There are long and high mountain ranges in northern and north eastern part of India in the form of Himalayan ranges. The Western Ghats and the Eastern Ghats lie to the west and east of the Peninsular region. The average altitude of the Greater Himalayas is around 6000m.	In Brazil there are no high and continuous mountain ranges. The eastern side of the Highlands is demarcated because of the Escarpment. The Great Escarpment located in south-eastern part of the Highlands has an altitude of 790m in this region with the height gradually decreasing.
In India the Plains occupy a wide area in the north. The Plains lie between the Himalayas in the North and the Peninsula in the South. It extends from Rajasthan in the West to Assam in the East. The Coastal Plains lie to the west and east of the Peninsula.	In Brazil the Amazon Basin in the North and the Parana-Paraguay Basin to the South West constitutes the Plains. Also a narrow coastal plain is confined to the North and the East.
The Peninsular Plateau region of India lies to the South of the North Indian Plains and is divided into 2 groups, the The Central Highlands and the Deccan Plateau.	In Brazil the Highlands occupy an extensive area in the South and is described as the Brazilian Highlands or the Brazilian Shield. Also to the North lies the Guyana Highland.
The islands in India are either volcanic or coral in origin.	The islands in Brazil are mainly depositional and some of them are coral in nature.

Question b.

Question d.
What could be the reasons behind the formation of swamps in the extensive continental location of Pantanal?
Answer:
Pantanal is one of the largest wetlands in the world, lying in the south west part of the highland areas.
It is a region of swamps and marshes in northwestern part of Mato Grosso do Sul in Brazil and it extends into Argentina too.
This region is drained by the river Paraguay and its tributaries.
They collect the water from the highland areas and deposit the sediments in the low lying Pantanal region.
Pantanal is a gently sloped basin which is submerged throughout the year due to the filling of the sediments and water in the depression area of the Pantanal.

Question e.
Which are the major water divides of India give examples.
Answer:
A mountain or an upland which separates two drainage basins is known as a Water Divide. The major Water Divides of India are :

4. Write geographical reasons:

Question a.
There are no west flowing rivers in Brazil.
Answer:
(i) Many rivers originating from the terminal portion of the Brazilian highlands flow northwards to meet the Amazon river and finally terminate in the Atlantic Ocean.

(ii) Sao Francisco River flows 1000 kms towards the north and then turns east to join the Atlantic Ocean.

(iii) The rivers Parana, Paraguay and Uruguay originating from the southern part of Brazilian highlands flow southwest and enter Argentina.

(iv) The Amazon river, originating from the Andes mountain in the west flows eastwards to meet the Atlantic Ocean.

(v) Thus, there are no west flowing rivers in Brazil.

Question b.
There are dissimilarities between the eastern and the western coast of India.
Answer:
(i) The western coast borders the Arabian Sea and the eastern coast borders the Bay of Bengal.

(ii) The western coast is by and large a rocky coast. At places, spurs starting from the Western Ghats have extended right up to the coast. The eastern coast has been formed as a result of depositional work of rivers.

(iii) The width of the western coast is narrow, whereas that of the eastern coast is wide.

(iv) Short and swift rivers originating from Western Ghats form estuaries on the western coast, whereas, because of the gentle slope the east flowing rivers flowing at low speed deposit sediments and form deltas on the eastern coast.

(v) Thus there are dissimilarities between the eastern and the western coasts of India.

Question c.
There are fewer natural ports on the eastern coast of India.
Answer:
(i) The eastern coast borders the Bay of Bengal. It has been formed as a result of depositional work of rivers.
(ii) Many east flowing rivers have formed deltas at their mouth due to the gentle slope.
(iii) Sediments deposited by the river makes the coast shallow.
(iv) Therefore there are fewer natural ports on the eastern coast of India.

Question d.
As compared to Amazon, the pollution in river Ganga affects human life greatly.
Answer:
(i) The Amazon Basin is a sparsely populated region of Brazil.. Unfavourable climate, heavy rainfall, inaccessibility and dense forest are the barriers for development of human settlements and industrialisation here.

(ii) On the other hand, the Ganga Plain region is one of the most densely populated regions of India.

(iii) Due to flat fertile plains, availability of water, suitable climate, dense human settlements have been established in this region.

(iv) Mining activities in the Amazon Basin causes pollution in the Amazon River, whereas industrial and domestic sewage adds to the pollution of

River Ganga. Thus as compared to Amazon, the pollution in River Ganga affects human life greatly, as the Ganga Plain is more densely populated as compared to the Amazon Plains.

Answer the following questions:

Question 1.
There are no deltas on the western coast of India.
Answer:
(i) Deltas are formed in the coastal areas where there is gentle slope, because the rivers slow down forming distributaries and channels.

(ii) The western coast bordering the Western Ghats are by and large rocky coasts having a narrow width.

(iii) Many short and swift seasonal rivers originate from the steep western slopes of the Western Ghats.

(iv) As the rivers flow through steep slopes, their velocity increases. So there is very little deposition
made by them.

(v) Hence, there are no deltas on the western coast of India.

Question 2.
Many deltas are found along the Eastern coast of India.
Answer:
(i) The eastern coast borders the Bay of Bengal. It has been formed as a result of depositional work of rivers.

(ii) Many east flowing rivers rising from the Western and Eastern Ghats after travelling a long distance join the Bay of Bengal at this coast.

(iii) Because of the gentle slope of the land, rivers flow at lower velocities and deposit the sediments brought with them at the coast.
Therefore, this coast is comparatively wider than the west.

(iv) As a result, deltas are found along the eastern coast of India.

Question 3.
The region to the north of the Escarpment is called Drought Quadrilateral.
Answer:
(i) The eastern side of the Highlands is demarcated because of the Escarpment having an altitude of 790 m.

(ii) The Escarpment acts as a barrier to the Southeast trade winds and cause orographic type of rainfall in the coastal region.

(iii) Beyond the highlands the effect of these winds gets reduced leading to minimal rainfall.

(iv) A rain shadow region is formed to the north east of the Escarpment. Thus, the region to the north of this area is called “Drought Quadrilateral”.

Question 4.
The Amazon Plains are covered by inaccessible tropical rainforest.
Answer:
(i) The northern part of Brazil lying between the Equator and the Tropic of Capricorn, i.e. in the Tropical zone is covered largely by the Amazon Plains.

(ii) Amazon plains lying between the Guyana highlands and the Brazilian highlands form the largest plain land of Brazil.

(iii) The Amazon valley receives very heavy rainfall of around 2000 mm and the average temperature here is 25 to 28°C.

(iv) These conditions favor the dense growth of tropical rain forests. Due to frequent flooding and dense undergrowth, these forests are largely inaccessible.

Question 5.

Question b.
What are the similarities and differences in the fishing activities in Brazil and India.
Answer:
Similarities:

• In Brazil and India fishing activity is developed near the coastal areas.
• In both the countries, marine fishing is well- developed.

Differences:

• In India, fresh water fishing is practised, whereas in Brazil due to unfavourable conditions, fresh water fishing is not developed.
• The meeting of the warm Brazil current and the cold Falkland current, off the coast of South-East Brazil makes it a good fishing ground. In India such currents do not come together but due to other favourable conditions fishing has been developed.
• Major fishes of Brazil are swordfish, shrimp, lobsters and sardines.
• Major fishes of India are mackerel, bombay duck, prawns, horse mackerels, clupeids, silver bellies and sardines.

3. Give reasons:

Question a.
Per capita land availability is more in Brazil as compared to India.
Answer:

• India occupies 2.4% land area of the world and supports 17.5% of the world’s total population.
• Brazil occupies 5.6% of land area of the world and supports only 2.75% of the world’s total population.
• Average density of population in India is about 382 persons per sq. km. while average density of population in Brazil is around 23 persons per sq. km.
• Thus Brazil’s population is lesser than India, but it occupies a larger land area than India.
• So, the per capita land availability is more in Brazil as compared to India.
