Q27 (UPPCS/2024) Geography › World Physical Geography

Given below are two statements, one is labelled as Assertion (A) and the other as Reason (R).
Assertion (A) : Relative humidity decreases with increasing air temperature.
Reason (R) : Absolute humidity increases with increasing evaporation.
Select the correct answer from the codes given below :

Both (A) and (R) are true, but (R) is not the correct explanation of (A).

(A) is false, but (R) is true.

Both (A) and (R) are true and (R) is the correct explanation of (A).

(A) is true, but (R) is false.

Result

Your answer: — · Correct: A

Explanation

Assertion (A) is true: Relative Humidity (RH) is the ratio of the actual water vapor present in the air to the maximum amount the air can hold (saturation capacity) at a specific temperature. As air temperature increases, its capacity to hold moisture increases. Therefore, if the actual moisture content remains constant, the RH decreases as temperature rises.

Reason (R) is true: Absolute Humidity (AH) is the actual mass of water vapor present in a unit volume of air. Evaporation is the physical process that converts liquid water into vapor, directly adding moisture to the atmosphere and thus increasing AH.

Relationship: While both statements are factually correct, (R) is not the explanation for (A). The decrease in RH mentioned in (A) is a result of the change in the air's saturation point due to temperature, not the process of evaporation or the resulting absolute moisture levels.
