Question

Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A) : Eastern depressions are responsible for heavy rainfall during June to September in India.
Reason (R) : Eastern depressions are mostly origited over Bay of Bengal and travel in north westerly direction across the country.
In the light of the above statements, choose the most appropriate answer from the options given below :

• A. Both (A) and (R) are correct and (R) is the correct explation of (A)
• B. Both (A) and (R) are correct but (R) is NOT the correct explation of (A)
• C. (A) is correct but (R) is not correct
• D. (A) is not correct but (R) is correct

Hint:

Monsoon depressions move from East to West/North-West across the Indian subcontinent, bringing major rainfall to Odisha, West Bengal, Jharkhand, MP, and UP.

Answer 1

The Correct Option is A

Step 1: Understanding the Question:
The question tests understanding of monsoon climatology, specifically how monsoon low-pressure systems (monsoon depressions) origiting in the Bay of Bengal contribute to rainfall across India during the South-West monsoon season (June--September).

Step 2: Alysis of Assertion (A):

• Monsool depressions (eastern depressions) forming over the head of the Bay of Bengal are key rainfall-producing systems during the summer monsoon (June--September).

• These depressions bring widespread heavy precipitation to central, eastern, and northern India.

• Hence, Assertion (A) is correct.

Step 3: Alysis of Reason (R):

• Eastern depressions origite in the Bay of Bengal and move inland along the monsoon trough in a West-North-Westerly direction towards central and north-western India.

• As these low-pressure systems travel westward, they transport massive moisture inland, causing widespread heavy rain along their track.

• This directiol movement directly explains why heavy rainfall is distributed across central and northern India during June to September.

• Thus, Reason (R) is correct and provides the direct meteorological explation for Assertion (A).

Step 4: Fil Answer:
Both (A) and (R) are correct and (R) is the correct explation of (A). Therefore, option (A) is the correct choice.
