Crumulus clouds
Cumulus clouds are fluffy white clouds. They look like balls of cotton in the sky. Children often draw cumulus clouds in their pictures. When you see cumulus clouds the weather is generally good, and the sky is blue. Cumulus clouds are low-level clouds. They are usually close to the ground,about 460to 915 meters above Earth's surface. A cumulus cloud forms when sunshine warm water vapor in the air. The warm water vapor rises and cools as it moves higher. The cool water vapor than changes into water droplets, and the the droplets join together and form a cumulus cloud.
