Front

How does warm air affect weather patterns?

Back

Warm air can lead to the formation of clouds and precipitation as it rises and cools.

Front

What happens at a cold front?

Back

At a cold front, cold air pushes under warm air, causing the warm air to rise and often resulting in storms.

Front

What is the difference between a warm front and a cold front?

Back

A warm front occurs when warm air rises over cold air, while a cold front occurs when cold air pushes under warm air.
