17
Q

Cold Front

A

cold air pushes warm air up and out; creates thunderstorms; bring colder temperatures; move fast

18
Q

Warm Front

A

warm air pushes cold air out; creates long-lasting light rain; bring warmer temperatures; move slow

19
Q

Stationary Front

A

two air masses meet; neither one is strong enough to push the other out; brings light wind and sometimes rain; do not move far or fast

20
Q

Occluded Front

A

fast air mass catches up to warm front and squeezes warm air up and out; creates strong winds and storms

Q

Stable Air

A

Makes fair weather clouds and a “nice day.”

22
Q

Unstable Air
