UNIT TEST - Atmosphere

Front

What is the main factor that determines whether water vapor will condense into liquid water?

Back

The dew point.

Front

What happens to relative humidity when the air temperature increases with constant water vapor?

Back

Relative humidity decreases.

Front

As you go higher in the troposphere, what happens to the temperature?

Back

The temperature decreases.

Front

Where do tropical air masses originate?

Back

Lower latitudes.

Front

What does a weather vane indicate?

Back

Wind direction.

Front

What is the definition of dew point?

Back

The temperature at which air becomes saturated with moisture and water vapor begins to condense into liquid.

Front

What is relative humidity?

Back

The amount of moisture in the air compared to the maximum amount of moisture the air can hold at that temperature.

Front

What is the relationship between temperature and relative humidity?

Back

As temperature increases, relative humidity decreases if the amount of water vapor remains constant.

Front

What is the troposphere?

Back

The lowest layer of Earth's atmosphere, where weather occurs and temperature generally decreases with altitude.

Front

What are tropical air masses characterized by?

Back

Warm temperatures and high humidity.
