Back

Hot air is less dense than cold air.

Front

What happens to air pressure as altitude increases?

Back

Air pressure decreases with increasing altitude.

Front

What is the relationship between air pressure and weather?

Back

Low pressure is often associated with cloudy and rainy weather, while high pressure is associated with clear skies.
