Original Project
Weather and Climate I: Basic Elements
Clouds and rain form as air cools and water vapor in the air condenses into water droplets.
Item WC079002: Clouds are made up of tiny water droplets that form as water vapor in the air condenses.
How are clouds related to water vapor and water droplets?
- Water vapor in the air condenses to form tiny water droplets, and these water droplets make up clouds.
- Water vapor in the air makes up clouds, but water vapor does not condense to form tiny water droplets that make up clouds.
- Water vapor in the air condenses to form tiny water droplets, but the water vapor and water droplets do not make up clouds.
- Water vapor in the air stays in the air as water vapor. The water vapor does not make up clouds, and it does not condense to form tiny water droplets.

- 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 composition of clouds.
