cloud formation
Cloud is a visible polymer suspended in the atmosphere, which consists of a large number of tiny water droplets, ice crystals and dust. Generally, if you don't touch the ground, it's called fog.

When the water in the air reaches saturation and condenses into a large number of tiny water droplets floating in the air, clouds are formed.
