Understanding Wind and Air Pressure

Front

What are global winds influenced by?

Back

Global winds are influenced by temperature changes over large areas, not just small areas.

Front

What instrument shows the direction the wind is blowing from?

Back

A wind vane shows the direction the wind is blowing from.

Front

What is an air mass?

Back

An air mass is a large body of air that has similar temperature and moisture characteristics.

Front

What type of air mass usually has warm, moist air?

Back

A low pressure (light) air mass usually has warm, moist air.

Front

True or False: An air mass can have different temperatures and moisture levels.

Back

False. An air mass has about the same temperature and moisture.

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 pressure?

Back

As temperature increases, air pressure usually decreases.

Front

What is a cyclone?

Back

A cyclone is a system of winds rotating inward to an area of low atmospheric pressure.

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 bringing clear skies.

Front

What is the Coriolis effect?

Back

The Coriolis effect is the deflection of moving objects caused by the rotation of the Earth.
