Air Pressure, Wind, Dewpoint, & RH

Front

What is the weight of air?

Back

Air has weight, even though it may not be easily perceived.

Front

What phenomenon causes cooler air to move out and warmer air to move in during a land breeze?

Back

Convection is the process that causes this movement.

Front

What causes all winds?

Back

Differences in air pressure.

Front

What is the Coriolis effect?

Back

The Coriolis effect is the curving of wind across Earth due to its rotation.

Front

What causes winds to curve?

Back

Winds curve due to Earth's rotation.

Front

How much energy is required to warm up a body of water compared to an equal area of land?

Back

It takes more energy to warm up a body of water than it does to warm up an equal area of land.

Front

What is air pressure?

Back

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

Front

How does temperature affect air pressure?

Back

As temperature increases, air pressure decreases, and vice versa.

Front

What is relative humidity (RH)?

Back

Relative humidity is the amount of moisture in the air compared to the maximum amount of moisture the air can hold at a given temperature.

Front

What is dew point?

Back

Dew point is the temperature at which air becomes saturated with moisture and water vapor begins to condense.
