Multiple Choice

_______ pressure systems are characterized by fair weather.

• High
• Low

Multiple Choice

Pressure is the effect of

• water vapor in the atmosphere
• greenhouse gases
• solar radiation

Multiple Choice

In what direction(s) does air exert pressure?

• everywhere
• no where
• there is no pressure
• downward

Multiple Choice

• at the center of the mountain

Multiple Choice

A device that is used to measure atmospheric pressure is a ___________.

• barometer
• thermometer
• kilometer
• micrometer

Multiple Choice

What happens to air pressure as you move upward into the atmosphere?
