Front

Why is air pressure greatest near Earth's surface?

Back

Air pressure is greatest near Earth's surface because air molecules are closer together.

Front

What is air pressure?

Back

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

Front

What is a high pressure system?

Back

A high pressure system is an area where the atmospheric pressure is higher than the surrounding areas, usually associated with clear skies.

What is a low pressure system?

Back

A low pressure system is an area where the atmospheric pressure is lower than the surrounding areas, often leading to cloudy and rainy weather.

Front

How do temperature changes affect air pressure?

Back

As temperature increases, air pressure decreases because warm air expands and becomes less dense.

Front

What role do air molecules play in air pressure?

Back

Air molecules collide with surfaces, creating pressure; more molecules mean higher pressure.
