transpiration

condensation

a large body of air with about the same temperature and humidity throughout

the amount of moisture in the air

a place where two different air masses meet

a cold air mass that bumps against a warm air mass

Cold air pushed warm air up and it cools & which causes thunderstorms

a cold air mass bumps against a warm air mass

a warm air mass meets a colder air mass and slowly rises over it

two air masses meet and stop moving

warm air mass gets caught between 2 cold air masses

A warm air mass and cold air mass meet, but neither moves

Two cold air masses are on either side of a warm air mass

Cold, dense air pushes warm air upwards

Warm air catches up to cold air and slides over it

Light rain showers that last for a couple of days

Heavy thunderstorms or ice storms followed by cold temperatures

Light rain showers followed by warmer temperatures

Clear dry weather

Cold Front

Warm Front

Stationary Front

Occluded Front

Because cold air is lighter than warm air

Because warm air is forced to rise quickly over cold air

Because cold air absorbs moisture from the ground

Because warm air sinks below cold air
