The moist adiabatic rate (MAR) is less than the dry adiabatic rate (DAR) as a result of the release of the latent heat of condensation within the rising parcel of air.

Question

Quizplus · Accepted Answer

The statement is correct. As a parcel of moist air rises and cools, water vapor condenses into liquid and releases latent heat. This latent heat slows down the rate of cooling, making the moist adiabatic rate less than the dry adiabatic rate.
