Features: The content of this book: Plants on the ground release a large amount of water vapor. When they encounter cold air, they condense in the sky to form clouds. The sun's radiation causes lakes and rivers on the ground to produce a lot of water vapor. This water vapor rises and condenses into clouds when it meets cold air. There are many small water droplets in the air. When they gather together, they form clouds. The moisture of the land is heated and evaporated into water vapor. When it rises to high altitudes and encounters suspended dust in the air, it condenses into small water droplets. These small water droplets gather together to form clouds. Clouds change color. High clouds are white, and low clouds are black. White clouds are naturally white. That's right!
