Relate the temperature of atmospheric gases to the production of rain.
a) when warm air rises quickly into colder atmospheric levels in an unstable updraft, the molecules condense together eventually becoming heavy enough to to fall as precipitation.
b) when temperate air rises quickly into tropical atmospheric levels in an unstable thermal, the molecules diffuse together eventually becoming compact enough to to fall as precipitation.

c) when cool air accelerates quickly into warmer atmospheric levels in an unstable draft, the molecules compress together eventually becoming expressive enough to to fall as precipitation.
d) when balmy air rises quickly into temperate atmospheric levels in an unstable downdraft, the molecules descend together eventually becoming expansive enough to to fall as precipitation.
