Question
Write a note about the following.
The water cycle
Solution
The movement of water is continuously taking place from the earth's surface to the earth's atmosphere. The process of evaporation, condensation, and rainfall is a continuous process. Due to the sun's heat, the water on the earth's surface is continuously evaporated. Since the water vapour is lighter than air, it rises high in the atmosphere. Due to cool temperatures at the heights, the water vapour condenses, forming fine droplets of water. These droplets later form clouds. When small droplets of water become heavier and bigger, they descend down on the earth in the form of rain. Rainwater mixes with different water bodies. The snowbound regions also show the melting of ice and glaciers. This water also eventually mixes with ocean waters. In this way, water moves in a cyclic manner, which is known as the water cycle.
