Water undergoes different processes in the environment and is found in different states during these processes. This cyclic process through which water circulates in the environment is called the water cycle. There are four main steps involved in water cycle

1) Evaporation

2) Condensation

3) Precipitation

4) Run off

Evaporation is the process through which water is converted into water vapour. Heat or sunlight converts water into water vapour. Water is also emitted from the leaves of the plants through the process of transpiration.

This water vapour in the atmosphere condenses to form clouds through the process of condensation.

When enough water is condensed to form clouds, it falls down on the surface of the Earth in the form of rain, snow, hail, etc. This process is known as precipitation.

The water that falls down as precipitation runs through the rivers and seeps underground. It also flows off the surface as surface run off to join low-lying water bodies. In this manner, water is circulated in the environment.

thumbs up plz!

The whole process in which water evaporates and falls down as rain and later flows into the sea via rivers is known as a water-cycle.
