Question

A weather front occurs when two air masses of differing temperatures meet. When a cold air mass meets a warm air mass, for example, what will happen to the warm air?
A.
It will sink.
B.
It will rise.
C.
Nothing will happen.
D.
It will reverse directions.

Answer 1

When a cold air mass meets a warm air mass, the warm air will rise.

So the correct answer is:
**B. It will rise.**

This occurs because warm air is less dense than cold air, causing it to rise above the colder, denser air.
