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 WC114001: Water vapor in air can come from water in plants and in the soil.
If the temperature of the air in a town is cool, and the town has no rivers or lakes and is not close to an ocean, could the air at that town have water vapor in it?
- No, the air at the town must be both warm and be close to a large body of water for the air to have water vapor in it.
- No, the air at the town does not have to be warm, but it must be close to a large body of water to have water vapor in it.
- No, the air at the town does not have to be close to a large body of water, but it must be warm to have water vapor in it.
- Yes, the air at that town could have water vapor in it because the water vapor can come from water in plants or soil even when the air is cool.
