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 WC066002: Air can become more humid if the temperature of the air increases or if the amount of liquid water in contact with the air increases.
What makes air become more humid one day than it was the day before?
- The only way the air can become more humid is if the temperature of the air increases.
- The only way the air can become more humid is if the amount of liquid water in contact with the air increases.
- The only way the air can become more humid is if both the temperature of the air and the amount of liquid water in contact with the air increase.
- Either increasing the temperature of the air or increasing the amount of liquid water in contact with the air can make the air more humid, but both do not need to increase to make the air more humid.

- 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.
- NRC Framework
- Practice 6: Constructing Explanations and Designing Solutions: ...evaluate…explanations for consistency with the evidence.
- Notes
- NGSS does not explicitly address the relationship between air temperature and how much water the air can hold.
