Question

• A. A. 1 only
  
• B. B. 3 only
  
• C. C. 2 & 3 only
  
• D. D. 1, 2, & 3

Answer 1

The correct option is D D. 1, 2, & 3

Ans: D
Nilgiri 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 amounts of rainfall over short periods. So, there is almost direct rock fall quite frequently in these places along with landslides and debris avalanches.
