What are clouds made of?

उत्तर
Clouds are made up of fine droplets of water. The sun's heat evaporates the water to form vapours from the earth's surface. This water vapour rises high up in the atmosphere. At cool heights, it condenses, forming fine droplets of water, which in turn make the clouds.
