Beautiful Science | The Science of Clouds
A cloud is a mass of tiny water drops or ice crystals that floats in the air above Earth. Water on land or in the ocean evaporates, turning from a liquid to a gas called water vapor. The water vapor rises, cools, and then turns back into a liquid, forming tiny droplets. Enough of these droplets make a cloud.
