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

The amount of water vapor in the air is known as:

• Cloud

• Temperature

• Humidity

• Dew Point

Dew (liquid water droplets) is most likely to form

• when the snow on the ground melts

• after heavy rain on a humid day

• during windy nights when it rains

• when warm humid air contacts cold ground

What change causes water vapor in the air to form clouds?

• as air rises in the atmosphere, it becomes warmer and cannot hold as much water

• as air rises in the atmosphere, it cools and water vapor in the air condenses to a liquid or solid state

• as air rises in the atmosphere, the air becomes heavier and changes forms

Summarize relative humidity is in one sentence.

• Relative humidity is the amout of water vapor in the air at the current temperature.

• Relative humidity is the amount of water vapor in the air at the current temperature related to the total amount it could hold at that temperature.

• Relative humidity is the temperature at which water vapor turns back into liquid water.

• Relative humidity is the temperature at whick clouds and fog form.

Which of the following shows the correct order of the water cycle?

• Radiation, precipitation, evaporation, condensation

• Radiation, condensation, evaporation, precipitation

• Radiation, precipitation, condensation, evaporation

• Radiation, evaporation, condensation, precipitation
