Weather Formative

A front is:

• where warm air cools off at Earth's surface

• where hot and cold air separate

• where two different air masses meet

• where cold air rises and forms rain clouds

When a cold front approaches, what happens?

• warm air is pushed under cold air, which causes humid weather and lower temperatures

• warm air is pushed under cold air, which causes humid weather and higher temperatures

• warm air rises and then cools down, and causes rain and thunderstorms

• cold air is pushed over warm air, which causes rain and thunderstorms
