Back

Altitude is the distance above sea level.

Front

What is air pressure?

Back

Air pressure is the force exerted by the weight of air molecules above a surface.

Front

How does temperature affect air pressure?

Back

As temperature increases, air pressure decreases.

Front

What is the relationship between air pressure and weather?

Back

High air pressure is usually associated with clear, sunny weather, while low air pressure can lead to storms.

Front

What happens to air pressure at higher altitudes?

Back

Air pressure decreases at higher altitudes.

Front

What is a vacuum?

Back

A vacuum is a space devoid of matter, including air, resulting in no air pressure.
