What Is Water Cycle?

It is the process by which water circulates between the earth`s surface, atmosphere and underground. It is a continuous cycle that plays a vital role in sustaining life on earth. The three main phases of water cycle are:

1) Evaporation: The water evaporates from oceans, rivers, lakes and plants due to heat of the sun. And gets converted into water vapors in the atmosphere.

2) Condensation: The water vapors get cools and form clouds in the sky which is known as condensation.

3) Precipitation: When it starts raining after the formation of clouds and water falls on the earth`s surface. It is called precipitation.
