clouds. We see them every day, But the majority of people don't know how these beautiful cotton candy like wonders are created. It would be easy to think that they are made of gas, but they are actually a large, visible mass of hundreds of trillions of tiny drops of liquid water. A cloud is formed when the sun shines over lakes and oceans, heating up the surface of the water, which then turns into water vapor. Then these begin to rise into the air through evaporation. As it goes higher and higher into the atmosphere, the water vapor begins to cool, turning the vapor by to water droplets. When cooled, the droplets collide and stick to tiny particles floating in the air, called condensation nuclei as they rise and cool further, the nuclei provides a surface for the droplets to condense, and when enough of it has formed around the nuclei, they hang suspended in the earth's atmosphere, and a beautiful cloud is formed after the water droplets combine. After some time, the clouds become heavier and the laws of gravity come into effect, bringing the accumulated water down as rain. They may look as light as a feather, but some clouds can weigh as much as 500 tons. That's about the weight of 100 elephants
