Why is the saturated adiabatic lapse rate less than the unsaturated adiabatic lapse rate?
A)The steepness of the lapse rate curves are identical.
B)Release of latent heat warms the local environment.
C)Absorption of latent heat causes a parcel of air to contract.
D)Absorption of latent heat warms the local environment.

The release of latent heat during condensation of water vapor within a parcel of saturated air causes the parcel to warm. This reduces the rate of cooling as the parcel rises, resulting in a lower adiabatic lapse rate compared to unsaturated air which does not release latent heat.
