PDE Q38
0. In determining the Indian climate, major role played by Himalayas is/are:
- A
The east-west extension of the Great-Himalayas does not permit the summer monsoon to cross it and thus keeps its sojourn restricted to India
- B
The direct the summer monsoon towards the north-west
- C
During the winter they stop the southward penetration of the cold and dry polar air
- D
All of the above
- Option : D
- Explanation :
The Himalayas play a crucial role in shaping the Indian climate in several ways. Their east-west orientation blocks the northward movement of the summer monsoon, ensuring that most of the rainfall stays within the Indian subcontinent. They also direct the monsoon winds towards the northwest and act as a barrier preventing the cold polar winds from entering India during winter, thus keeping the region relatively warmer.
-
Option A: The east-west extension of the Great-Himalayas does not permit the summer monsoon to cross it and thus keeps its sojourn restricted to India
Correct. The Himalayas block the monsoon from moving further north into Central Asia, causing it to unload moisture over India. -
Option B: They direct the summer monsoon towards the north-west
Correct. The orientation and height of the Himalayas help deflect the monsoon winds toward northwest India and the Indo-Gangetic plains. -
Option C: During the winter they stop the southward penetration of the cold and dry polar air
Correct. The Himalayas shield the Indian subcontinent from severe cold winds from Central Asia during winter. -
Option D: All of the above
Correct. All the above roles collectively explain how the Himalayas shape India’s climate.
