• Question 1 of 5 1. Question Which of the following mountain ranges is parallel to the main Himalayan range and lies to the north of the Yarlung Tsangpo River? a) Zanskar Range b) Trans Himalayas c) Pir Panjal Range d) Karakoram Range Correct Solution: b) The Trans Himalayas extend in a west-east direction and are located north of the Yarlung Tsangpo River, forming the southern edge of the Tibetan Plateau. These ranges run parallel to the main Himalayan range. They are composed of granites and volcanic rocks, distinguishing them from the main Himalayas. The Trans Himalayas are not divided by deep river gorges, unlike the main Himalayas, and they play a crucial role in India’s geography, serving as part of its northern frontier with China. Incorrect Solution: b) The Trans Himalayas extend in a west-east direction and are located north of the Yarlung Tsangpo River, forming the southern edge of the Tibetan Plateau. These ranges run parallel to the main Himalayan range. They are composed of granites and volcanic rocks, distinguishing them from the main Himalayas. The Trans Himalayas are not divided by deep river gorges, unlike the main Himalayas, and they play a crucial role in India’s geography, serving as part of its northern frontier with China.

#### 1. Question

Which of the following mountain ranges is parallel to the main Himalayan range and lies to the north of the Yarlung Tsangpo River?

• a) Zanskar Range

• b) Trans Himalayas

• c) Pir Panjal Range

• d) Karakoram Range

Solution: b)

The Trans Himalayas extend in a west-east direction and are located north of the Yarlung Tsangpo River, forming the southern edge of the Tibetan Plateau. These ranges run parallel to the main Himalayan range. They are composed of granites and volcanic rocks, distinguishing them from the main Himalayas.

• Question 2 of 5 2. Question Consider the following statements about the Trans Himalayas: They are mainly composed of sedimentary rocks. The Trans Himalayas are divided by deep river gorges, similar to the main Himalayas. The Trans Himalayas represent an Island Arc. Which of the statements given above is/are correct? a) 3 only b) 1 and 2 only c) 2 and 3 only d) None of the above Correct Solution: a) Statement 1 is incorrect because the Trans Himalayas are primarily composed of granites and volcanic rocks, not sedimentary rocks. This composition is different from the sedimentary rock formations commonly associated with the main Himalayan ranges. Statement 2 is also incorrect as the Trans Himalayas, unlike the main Himalayan range, are not divided by deep river gorges. They lack the clear river valleys that carve through the main Himalayas. Statement 3 is correct because the Trans Himalayas are part of a larger tectonic system that represents an Island Arc. This formation occurred due to the collision of the Indian Plate and the Eurasian Plate, resulting in the uplift of this range. Incorrect Solution: a) Statement 1 is incorrect because the Trans Himalayas are primarily composed of granites and volcanic rocks, not sedimentary rocks. This composition is different from the sedimentary rock formations commonly associated with the main Himalayan ranges. Statement 2 is also incorrect as the Trans Himalayas, unlike the main Himalayan range, are not divided by deep river gorges. They lack the clear river valleys that carve through the main Himalayas.

• Question 3 of 5 3. Question Consider the following statements about the Tethys Himalayas: They are composed of marine-origin sediments. Zaskar and Kailash ranges are part of the Tethys Himalayas. The Tethys Himalayas are clearly separated from the Greater Himalayas. How many of the above statements is/are correct? a) Only one b) Only two c) All three d) None Correct Solution: b) Statement 1 is correct: The Tethys Himalayas were formed from the compression of marine-origin sediments that were deposited in the ancient Tethys Sea. These sediments were metamorphosed during the collision between the Indian and Eurasian plates. Statement 2 is correct: The Zaskar and Kailash ranges are indeed part of the Tethys Himalayas, forming significant geological features within this range. Statement 3 is incorrect: There is no clear separation between the Greater Himalayas and the Tethys Himalayas. These two geological formations are often interrelated and part of the same larger tectonic system. Incorrect Solution: b) Statement 1 is correct: The Tethys Himalayas were formed from the compression of marine-origin sediments that were deposited in the ancient Tethys Sea. These sediments were metamorphosed during the collision between the Indian and Eurasian plates.

• Question 4 of 5 4. Question Which of the following best describes the Bhabar plains? a) A marshy tract with rich vegetation and wildlife b) A region formed by younger alluvium from rivers, ideal for agriculture c) A narrow belt of 8-10 km parallel to the Shiwalik foothills where streams deposit heavy materials like rocks and boulders d) A deltaic region with marshy lands known as Bils Correct Solution: c) The Bhabar plains are a narrow belt that runs parallel to the Shiwalik foothills, with a width of around 8-10 km. Due to the break in slope at this point, rivers descending from the mountains lose their velocity, causing them to deposit heavy materials such as rocks and boulders in this region. The porous soil in Bhabar causes many rivers to disappear before re-emerging in the Tarai region, located just south of Bhabar. This zone is not suitable for agriculture, but it supports large trees with deep roots.
