Air Pressure & Wind

Front

What is air pressure?

Back

Air pressure is the force exerted by the weight of air above a surface. It decreases with altitude.

Front

What happens to air pressure as altitude increases?

Back

Air pressure decreases as altitude increases.

Front

What is the relationship between temperature and air density?

Back

Warmer air is less dense than cooler air.

Front

What is a low pressure area?

Back

A low pressure area is a region where the atmospheric pressure is lower than that of surrounding areas, typically associated with warmer, less dense air.

Front

What is a high pressure area?

Back

A high pressure area is a region where the atmospheric pressure is higher than that of surrounding areas, usually associated with cooler, denser air.

Front

How does air density affect air pressure?

Back

As air density increases, air pressure increases because more air molecules are present in a given volume.

Front

What is the significance of air having mass?

Back

Air having mass means it exerts pressure and can affect weather patterns and climate.

Front

What is wind?

Back

Wind is the movement of air from areas of high pressure to areas of low pressure.

Front

What causes wind?

Back

Wind is caused by differences in air pressure, which are often due to temperature variations.

Front

What is the Coriolis effect?

Back

The Coriolis effect is the deflection of moving objects, such as wind, caused by the rotation of the Earth.
