Multiple choice

Directions: The following question consists of two statements, one labelled as Assertion (A) and the other labelled as Reason (R). You are to examine these two statements carefully and decide if the Assertion (A) and the Reason (R) are individually true and if so, whether the Reason is the correct explanation of the Assertion. Select your answer using the codes given below.Assertion (A) : The moist adiabatic lapse rate is lower than the dry adiabatic lapse rate. Reason (R) : When condensation begins, the latent heat of condensation is released in the parcel of air.

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

  2. Both A and R are correct but R is not the correct explanation of A.

  3. A is true but R is false.

  4. A is false but R is true.

A Correct answer
Explanation

The moist adiabatic lapse rate is lower than the dry adiabatic lapse rate because the release of latent heat during condensation offsets some of the cooling that occurs as the air parcel rises and expands. Both statements are correct and directly causally related.
