Question

Assertion (A): Drainage increases the soil temperature.
Reason (R): Drainage decreases the heat capacity.

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

Hint:

In assertion-reason questions, ensure that both statements are not only correct but logically connected.

Answer 1

The Correct Option is A

Well-drained soils retain less water, lowering their heat capacity, allowing them to warm up more quickly. Thus, drainage increases soil temperature by reducing heat retention.
