The rate at which the actual air temperature decreases with increasing height above the surface is referred to as the ____ rate.

• dry adiabatic
• environmental lapse
• moist adiabatic

The difference between "moist" and "dry" adiabatic rates is due to the fact that

• saturated air is always unstable.
• an unsaturated air parcel expands more rapidly than a saturated air

parcel.

• moist air weighs less than dry air.
• latent heat is released by a rising parcel of saturated air.
• moist air weighs more than dry air. - ANSWER-latent heat is released

by a rising parcel of saturated air
