Question: The dry adiabatic rate is the rate at which:
an air parcel rises.
temperature changes in a rising or descending parcel of unsaturated air.
volume changes when a parcel expands or is compressed.
latent heat energy is released in a rising air parcel.
Answer: temperature changes in a rising or descending parcel of unsaturated air.

snow
hail
freezing rain
sleet
rain
Answer: freezing rain
Question: The reason that rising saturated air cools at a lesser rate than rising unsaturated air is:
rising saturated air is heavier.
rising saturated air is lighter.
unsaturated air expands more rapidly.
latent heat is released by rising saturated air.
Answer: latent heat is released by rising saturated air.
Question: The rate at which the temperature changes inside a rising (or descending) parcel of saturated air is called:
the environmental lapse rate.
the dry adiabatic lapse rate.
the moist adiabatic lapse rate.
the latent heat release rate.
Answer: the moist adiabatic lapse rate.
