Q48.
When you travel in Himalayas, you will see the following: 1. Deep gorges 2. U-turn river courses 3. Parallel mountain ranges 4. Steep gradients causing land-sliding. Which of the above can be said to be the evidence for Himalayas being young fold mountains?
A. 1 and 2 only
B. 1, 2 and 4 only
C. 3 and 4 only
D. 1, 2, 3 and 4
Answer

D

Explanation

All four features are evidence of the Himalayas being young fold mountains: (1) Deep gorges form because rivers are older than the mountains and continue cutting downward as uplift occurs. (2) U-turn river courses (antecedent drainage) show rivers predating the mountains. (3) Parallel mountain ranges are characteristic of fold mountain systems. (4) Steep gradients and landslides indicate the mountains are still young, unstable, and tectonically active. These are all classic evidences of young fold mountains.
