Air Pressure, Density and temperature

Front

What is air pressure?

Back

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

Front

Why is air pressure greatest near Earth's surface?

Back

Because the air molecules are closer together.

Front

What causes differences in air pressure around Earth?

Back

Warm air rises at the equator, and cold air sinks at the poles.

Front

What is the relationship between altitude and air pressure?

Back

Air pressure decreases as altitude increases.

Front

What is the density of air at high altitudes?

Back

The density of air is lower at high altitudes.

Front

What does air consist of?

Back

Air consists of molecules, primarily nitrogen and oxygen.

Front

What is altitude?

Back

Altitude is the distance above sea level.

Front

How does temperature affect air pressure?

Back

Warm air is less dense and rises, leading to lower air pressure.

Front

What happens to air pressure when air cools?

Back

When air cools, it becomes denser and sinks, increasing air pressure.

Front

What is the role of air pressure in weather?

Back

Air pressure influences weather patterns and systems.
