Weather and Climate I: Basic Elements
The amount of water vapor in the air at any place depends on the amount of liquid water available on the surface…
Item WC075002: Both the amount of liquid water beneath the air and the temperature of the air affect the humidity of air.
Which of the following affects the amount of water vapor in the air as air moves over the surface of the earth?
- Both the amount of liquid water beneath the air and the temperature of the air affect the amount of water vapor in the air.
- The amount of liquid water beneath the air affects the amount of water vapor in the air, but the temperature of the air does not.
- The temperature of the air affects the amount of water vapor in the air, but the amount of liquid water beneath the air does not.
- Neither the amount of liquid water beneath the air nor the temperature of the air affects the amount of water vapor in the air.

- Disciplinary Core Ideas
- ESS2.C Water continually cycles among land, ocean, and atmosphere via transpiration, evaporation, condensation and crystallization, and precipitation, as well as downhill flows on land.
- Notes
- NGSS does not explicitly address the relationship between air temperature and the amount of water vapor air can hold.
