All About Clouds!

How are clouds formed? Clouds are formed when warm air rises. This air expands and cools. Because cool air can’t hold as much water as warm air, some of the vapor condenses onto tiny pieces of dust that are floating in the air. A tiny droplet forms around each dust particle. They become a visible cloud when billions of these droplets come together.

What is a cloud? A cloud is a large collection of very tiny droplets of water or ice crystals. The droplets are so small and light that they can float in the air.
