Q. Consider the following Assertion (A) and Reason (R):
Assertion (A): The weakening of the Atlantic Meridional Overturning Circulation (AMOC) can affect the timing of the Indian monsoon and cause droughts in the African Sahel.
Reason (R): AMOC circulates warm water north and cold water south, distributing heat and nutrients across the world’s oceans, and its collapse disrupts global climate patterns.
Choose the correct option:

[A] Both A and R are true, and R is the correct explanation of A.

[B] Both A and R are true, but R is not the correct explanation of A.

[C] A is true, but R is false.

[D] A is false, but R is true.

Answer: A
Notes:

Explanation:

  • Assertion: A weakening of AMOC affects global climate, including the timing of the Indian monsoon and rainfall patterns in the African Sahel.
  • Reason: AMOC drives oceanic heat redistribution, and its collapse can alter global precipitation, temperature patterns, and tropical rain belts, directly leading to the impacts mentioned in the assertion.
