18
Q

Front

A

Boundary between 2 unlike air masses

19
Q

Cold front

A

When a cold air mass moves into a warm air mass

(Causes short storms and colder weather - fastest moving

Warm front

A

When a warm air mass moves into a cold air mass

Steady precipitation lasting several days, then warmer weather

Q

Greenhouse Effect

A

When gases in Earth’s atmosphere trap heat and keep the climate warm. (Some of this is necessary)

25
Q

Global Warming

A

When too much of the greenhouse gases get in the atmosphere; will cause the Climate to get too warm.
