The water cycle can be defined as the continuous movement of water between the surface of the earth and the air, through which the water turns from liquid to gaseous, and then returns to the liquid state again.

Water cycle stages

Water passes through several stages, as follows: [2]

Absorption of ocean water and rivers running to the heat of the sun evaporation occurs (Evaporation).
The rise of steam into the atmosphere to condensation occurs in the form of drops forming clouds, falling in the form of rain and cold, and snow.
Some of the water is absorbed by the soil and the roots of the plants for use in their biological processes to evaporate later from the surface of the surface of the earth. The leaves are in the transpiration process.
