What causes a sea breeze?

Back

A sea breeze occurs because air over land heats faster than air over water, which causes convection.

What is the difference between high pressure and low pressure?

Back

High pressure is associated with sinking air and clear skies, while low pressure is associated with rising air and cloudy, stormy weather.

Front

What is the effect of altitude on air pressure?

Back

As altitude increases, air pressure decreases because there is less air above pushing down.

Front

What is the relationship between temperature and air pressure?

Back

Generally, as temperature increases, air pressure decreases because warm air rises.
