: Adiabatic temperatures changes in an air mass happen without a gain or loss of heat energy in the air mass.
t
f
The wet, or moist, adiabatic rate is less than the dry adiabatic rate due to the release of (a) heat during condensation. (one word, correct spelling)

more humid
saturated
condensated
cleared
warmer
Select all the objects below that may form due to air becoming saturated.
dew
rain
clouds
fog
air with a relative humidity of zero
Fog is a cloud at ground level formed when air warms and becomes unsaturated.
t
f

t
f
(a) lifting, or the rainshadow effect, occurs when air is pushed up and over a mountain range. (one word, correct spelling, no spaces)
