Question

Assertion (A): Forests are much cooler than deserts.

Reason (R): Vegetation reflects back the insolation.

पर्याय

• Both A and R are true, and R is the correct reason for A.

• Both A and R are true, but R is not the correct reason for A.

• A is true, and R is false.

• A is false, and R is true.

Answer 1

Both A and R are true, and R is the correct reason for A.

Explanation:

Forests are much cooler than deserts because vegetation reflects back a portion of the insolation (incoming solar radiation), which reduces the amount of heat absorbed by the surface. Additionally, vegetation also limits the release of heat (terrestrial radiation) from the Earth’s surface. This reflection and coverage by the forest canopy result in lower temperatures in forests compared to exposed desert areas. Hence, the reason that “vegetation reflects back the insolation” correctly explains why forests remain cooler than deserts.
