Q : 4 How are clouds formed?
Heating of the water bodies during the day leads to the evaporation of a large amount of water which then rises up with the hot air.
As the air rises, it expands and cools. This cooling causes the water vapour in the air to condense in the form of tiny droplets around dust particles.
These tiny droplets cluster themselves to form clouds. When these water-drops become heavy, they precipitate and fall down as rain.
In a nutshell, evaporation and condensation are the two main processes involved in the formation of cloud.
