Q2. The ‘Malda fault’ separates:

A. Northeastern parts of Peninsular Plateau from Chotanagpur Plateau.

B. Rajasthan from Peninsular Plateau.

C. Himalayas from North-Plains.

D. Western Ghats from Eastern Ghats.

Explanation:

The northern boundary of the Peninsular Block may be taken as an irregular line running from Kachchh along the western flank of the Aravali Range near Delhi and then roughly parallel to the Yamuna and the Ganga as far as the Rajmahal Hills and the Ganga delta. Apart from these, the Karbi Anglong and the Meghalaya Plateau in the northeast and Rajasthan in the west are also extensions of this block. The northeastern parts are separated by the Malda fault in West Bengal from the Chotanagpur plateau.


Q3. “The Peninsula mostly consists of relict and residual mountains” like:

1. Aravali hills

2. Nallamala hills,

3. Javadi hills

4. Veliconda hills

Select the correct answer using the code below

Explanation:

The Peninsula mostly consists of relict and residual mountains like the Aravali hills, the Nallamala hills, the Javadi hills, the Veliconda hills, the Palkonda range and the Mahendragiri hills, etc.


Q4. The Nilgiris along the west coast are relatively tectonically stable as compared to the Himalayas; but, still, debris avalanches and landslides occur though not as frequently as in the Himalayas, in these hills. Why?

1.Many slopes are steeper with almost vertical cliffs and escarpments in the Western Ghats and Nilgiris.

2.Mechanical weathering due to temperature changes and ranges is pronounced in this region.

3.They are mostly made up of sedimentary rocks and unconsolidated and semi- consolidated deposits.

4.They receive heavy amounts of rainfall over short periods.

A. 1, 2 and 3

B. 2, 3 and 4

C. 1, 2 and 4

D. 1 and 4

Explanation:

The debris avalanches and landslides occur very frequently in the Himalayas because the Himalayas are tectonically active. They are mostly made up of sedimentary rocks and unconsolidated and semi-consolidated deposits. The slopes are very steep. Compared to the Himalayas, the Nilgiris bordering Tamil Nadu, Karnataka, Kerala and the Western Ghats along the west coast are relatively tectonically stable and are mostly made up of very hard rocks; but, still, debris avalanches and landslides occur though not as frequently as in the Himalayas, in these hills. Why? Many slopes are steeper with almost vertical cliffs and escarpments in the Western Ghats and Nilgiris. Mechanical weathering due to temperature changes and ranges is pronounced. They receive heavy amount of rainfalls over short period.

3. Dense vegetation over Western Ghats.

Select the correct answer using the code given below.

A. 1 and 3 only

B. 2 only

C. 1 and 2 only

D. 2 and 3 only

Explanation:

Statements 1 and 2 are correct: Due to continuous nature of Western ghats against the Eastern Ghats

which comprise of isolated hills, Western Ghats provide a better barrier to monsoon winds.

Similarly the abrupt wall like rise of Western Ghats forces the monsoon winds to ascend and cause

heavy rainfall in the windward side.

Additionally, the Arabian Sea branch hits the Western ghats in perpendicular direction. On the other

hand Bay of Bengal branch remains parallel to Eastern Ghats in Tamil Nadu which does not receive much rainfall from south west monsoon.

Statement 3 is not correct: As distribution of rainfall in India is mainly orographic in nature, it is decided by the relief features, and not the vegetation.

3. Anamalai : Karnataka

Which of the pairs given above is/are correctly matched?

A. 1 and 2 only

B. 1 and 3 only

C. 1 only

D. 2and 3 only

Explanation:

The Western Ghats are locally known by different names such as Sahyadri in Maharashtra, Nilgiri hills in Karnataka, and Tamil Nadu and Anaimalai hills and Cardamom hills in Kerala. The Western Ghats are comparatively higher in elevation and more continuous than the Eastern Ghats. Their average elevation is about 1,500 m with the height increasing from north to south. ‘Anaimudi’ (2,695 m), the highest peak of Peninsular plateau is located on the Anaimalai Hills of the Western Ghats followed by Dodabetta (2,637 m) on the Nilgiri hills. Most of the Peninsular rivers have their origin in the Western Ghats. Hence option (1 and 2 only) is the correct answer.


Q14. Consider the following statements:

1. The Western Ghats are comparatively higher in elevation to the Eastern Ghats.

2. The Western Ghats are less continuous than the Eastern Ghats.

3. The average height of Western Ghats increases from north to south.

Which of the statements given above are correct?

A. 1, 2 and 3

B. 1 and 2 only

C. 1 and 3 only

D. 2 and 3 only

Explanation:

The Western Ghats in the west, and the Eastern Ghats in the east border the Deccan Plateau from both the sides.

The Western Ghats are comparatively higher in elevation. Hence statement 1 is correct. They are

also more continuous than the Eastern Ghats. Hence statement 2 is not correct.

Their average elevation is about 1,500 m with the height increasing from north to south. Hence, statement 3 is correct.

‘Anaimudi’ (2,695 m), the highest peak of Peninsular plateau is located on the Anaimalai Hills of the Western Ghats.

Most of the Peninsular rivers have their origin in the Western Ghats.The Eastern Ghats comprising the discontinuous and low hills are highly eroded by rivers such as the Mahanadi, the Godavari, the Krishna, the Kaveri, etc. Some of the important ranges include the Javadi hills, the Palkonda range, the Nallamala hills, the Mahendragiri hills, etc. The Eastern and the Western Ghats meet each other at the Nilgiri hills.


Q15. Residual mountains are formed as a result of erosion of an existing elevated area. Which of the following hills are residual hills or mountains?

1. Aravallis

2. Satpura hills

3. Javadi hills

Select the correct answer using the code given below.

A. 2 and 3 only

B. 1 and 2 only

C. 1 and 3 only

D. 1, 2 and 3

Explanation:

Residual Mountains:

The weathering and different agents of erosion – rivers, winds, glaciers, etc. are constantly acting on the earth’s crust. This process of erosion depends on the shape and structure of the rocks. Due to the agents of erosion, the softer rocks of the upland are eroded much more rapidly than the areas of harder rock. After thousands of years, soft rocks are worn down into the sand and the hard rocks are left standing up in the area that has been reduced in height. These are called residual mountains. The residual mountains are also called relict mountains. Examples of Residual Mountains in India are the Nallamala hills, Mahendragiri hills, the Aravalli hills, the Javadi hills, the Veliconda hills, and the Palkonda range. Hence option (c) is the correct answer.

Q18. Consider the following statements and choose the correct ones:

1. There is a variation of nearly 30 degrees, which causes a time difference of nearly two hours between the easternmost and the westernmost parts of our country.

2. Chai Bagaan time or tea time is a reference to an informal practice followed in tea gardens in Assam which is an hour ahead of IST.

Select the correct answer using the codes below

A. 1 only

B. 2 only

C. Both 1 and 2

D. Neither 1 nor 2

Explanation:

There is a variation of nearly 30 degrees, which causes a time difference of nearly two hours between the easternmost and the westernmost parts of our country. While the sun rises in the northeastern states about two hours earlier as compared to Jaisalmer, the watches in Dibrugarh, Imphal in the east and Jaisalmer, Bhopal or Chennai in the other parts of India show the same time.

Bagaan time or tea time is a reference to an informal practice followed in tea gardens in Assam which is an hour ahead of IST.


Q19. With reference to the geographical extent of India, consider the fo observations:

1.The difference between extreme latitudes is around 29° while the dif between extreme longitudes is around 32°

2.The length of India’s coastline is approximately half of the land border.

Which of the above is / are correct observations?

A. Only 1

B. Only 2

C. Both 1 & 2

D. Neither 1 nor 2

Explanation:

Lying entirely in the northern hemisphere, the mainland extends between l 8°4’ and 37°6’ north, longitudes 68°7’ and 97°25’ east and measures abo km from north to south between the extreme latitudes and about 2,933 east to west between the extreme longitudes. It has a land frontier of above km. The total length of the coastline of the mainland, Lakshadweep Island Andaman & Nicobar Islands is 7,516.6 km.


Q20. Consider the following statements:

1. The longitudinal extent between the eastern and the western side of India is about 30 degrees.

2. The north-south (latitudinal) extent of India is greater than its east-west (longitudinal) extent.

Which of the statements given above is /are correct?

A.1 only

B. 2 only

C. Both 1 and 2

D. Neither 1 nor 2

Explanation:

The latitudinal and longitudinal extent of India is roughly 30 degrees, whereas the actual distance measured from north to south extremity is 3,214 km, and that from east to west is only 2,933 km. Hence both statements 1 and 2 are correct. From the values of longitude, it is quite discernible that there is a variation of nearly 30 degrees, which causes a time difference of nearly two hours between the easternmost and the westernmost parts of our country. India is away from the equator. So, the lines of longitude come nearer and the East-West distance becomes less than the North-South distance. The distance between any two lines of longitude is maximum at the equator and goes on decreasing as one goes from the equator to the poles. The distance between lines of latitude remains the same at all latitudes.
