Relative Humidity

occurs when air/clouds are filled to 100% capacity of water.

• oscillation

• precipitation

• concentration

• participation

The time of day when the relative humidity reaches a maximum value is usually

• at the time when the air temperature is highest 

• in the middle of the afternoon 

• at the time when the air temperature is lowest 

• just before sunrise

Dew Point is the

• temperature air cools down to reach condensation (or turn into a liquid)

• temperature where ice melts to liquid water

• temperature where ice turns directly into water vapor

• time of day when dew on the ground disappears

Dew is most likely to form 

• after heavy rain on a humid day

• when humid air contacts cold ground

• when the snow on the ground melts

• during windy nights when it rains

As the air temperature increases, the air's capacity for water vapor: 

• increases

• decreases

• remains the same

• is unrelated to air temperature and can either increase or decrease

The sun heats up surface water, causing evaporation (turning a liquid into a gas).  The water vapor then rises into the air creating....

• rain

• pollution

• fog

• humidity

• evaporation

• precipitation

• condensation

• sublimation

What is relative humidity?

• humidity that is related to other humidity

• condensation

• clouds

• the amount of water in the air compared to the amount of water the air can hold - a ratio

Which type of air has a relative humidity of 100%?

• space

• hot

• dry

• saturated

What is the definition of relative humidity?

• The amount of water vapor in the air compared to the maximum amount the air can hold at that temperature

• The total amount of water vapor in the air

• The temperature at which air becomes saturated

• The pressure exerted by water vapor in the air
