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 WC084002: Rain falls from clouds when air cools, causing water droplets to form.
What makes rain fall from a cloud?
- Rain falls from a cloud any time wind blows on the clouds.
- Rain falls from a cloud when two clouds collide, causing them to burst open.
- Rain falls from a cloud when the air in the cloud cools, causing water droplets to form.
- Rain falls from a cloud when the pool of water in the cloud becomes too large, so the cloud can no longer hold the water inside.
