The What, Why and Kinds of Clouds for kids

When we look up we always see clouds, right? They are white, black or grey, but they are always there.

So what are clouds actually?

Clouds are nothing but a collection of water. Water from evaporation or water that is carried away by wind. reaches up to the sky.

The tiny water droplets cool down up in the sky. And they stick together to stay together. 

When the droplets become big enough they get pulled down due to gravity and that’s rain.

So why are some clouds white and some gray or black?

Lighter clouds reflect all light so when we see it, that appears white.

But denser clouds scatter all light so none of that reaches our eyes. So they appear dark to us.

Is there any use to clouds? Yes, they bring us rain?

Clouds keep the earth cooler during the day by reflecting sunlight.

During the night they keep us warm by holding the heat.

By the way, do you know what fog is? It is nothing but cloud on the ground.

And snow is nothing but rain droplets that fall from clouds in very cold weather. 

The dark clouds disappear after rain because the water droplets that formed those clouds have all rained.

Clouds are not only found in the Earth. And they are not only formed by water droplets.

Clouds in Venus are made up of droplets of Sulphuric acid, and Chlorine. Such clouds are poisonous clouds.

Clouds in Jupiter are made of ammonia.

Clouds in Mars are formed with water droplets.

So now you know the Science of clouds, rain and snow, right?
