Question

Which of the following evidence proves that the Himalayas are still rising?

1. Fossil formation found in Shivalik hills.

2. Youthful nature of rivers.

3. Frequent Earthquakes

1. 1 and 2 only
2. 2 and 3 only
3. 1 and 3 only
4. 1, 2 and 3

Answer 1

Correct Answer - Option 4 : 1, 2 and 3

The correct answer is 1, 2, and 3.

• The “Himalaya” means “the Abode of Snow”.
• The Himalayas are the highest as well as the longest Young Fold Mountains of the world.
• The Pamir knot (roof of the world) connects the Himalayas with Central Asia.
• Evidence that shows that the Himalayas are still rising:

1. Fossil formation found in Shivalik hills: Similar fossils have been discovered in the Tibet Plateau indicating that in the past both shared a common location Tibetan plateau. Hence, Statement 1 is correct.
2. Desiccation of lakes of Tibet: We find deposits in the Tibetan Plateau that are generally found in lakes. This indicates that lakes once existed in Tibet but because of upliftment the water got discharged and deposits remained.
3. Frequent Earthquakes. Hence, Statement 3 is correct.
4. Youthful nature of rivers (High erosion, v-shaped valleys, etc.) Hence, Statement 2 is correct.

• The Himalayas consist of a series of parallel mountain ranges:
• The North-South division of the Himalayas

1. The Greater Himalayan range, which includes the Great Himalayas (Himadri)
2. The Trans-Himalayan range including the Lesser Himalayas (Himachal)
3. The Outer Himalayas (Shiwalik).
