Q. Consider the following statements:
1.The rise of Himalayas and Tibetan plateau plays a significant role in shaping the evolution of the Indian monsoon.
2.An increase in high-latitude ice volume strengthens the Indian monsoon.
3.Aerosol forcing has decreased the strength of monsoon in recent years.
Which of the statements given above is/are correct?
Answer: B
Notes:
Explanation –
Statements 1 and 3 are correct. The rise of Himalayas and Tibetan plateau plays a significant role in shaping the evolution of the Indian monsoon because they determine largely where the locus of heating is in summer, which drives low pressure over India and pulls in moisture from the ocean. Aerosol forcing has decreased the strength of monsoon in recent years.
Statement 2 is incorrect. There is a relationship between high-latitude ice volume and the strength of the monsoon. When high-latitude ice volume is high, it tends to weaken the monsoon, whereas low ice volume tends to strengthen it.
