Answer 2

A cloud is a large collection of very tiny droplets of water or ice crystals. The droplets are so small and light that they can float in air. Clouds appear white because they reflect the light of the sun. Light is made up of colours of rainbow and when they are added up together, white colour is obtained clouds reflect all the colours by exactly the same amount so they generally look white.
