What are Clouds Made of?
The beautiful clouds you see in the sky – sometimes white as milk, sometimes dark and sometime shining and coloured, are simply billions and billions of minute droplets of water or tiny crystals of ice clustered together.
The water that makes clouds comes from the earth. The heat of the sun evaporates tons and tons of water every day from all parts of the earth. Lakes, rivers, ponds, puddles, ocean, plants, our bodies all add to this moisture. The evaporated water goes upwards in the form of water-vapour.
When the warm water vapour goes higher and higher, it begins to cool. This makes it change back into water or ice. These droplets together make up the clouds.
Some clouds are all water, some are all ice, some are a mixture. The droplets are so tiny that even a slightest wind is enough to keep them floating in the sky. If they join together and form large drops then they fall down on the earth and what we have is a rainfall.
