Water cycle is a very simple process and is also called the ‘Hydrologic cycle’.

Water cycle provides us with freshwater continuously.

The cycle keeps repeating itself.

The water cycle is made up of the following processes:1. Evaporation 2. Condensation3. Precipitation4. Collection

Evaporation• The sun heats up water in rivers, lakes

and oceans.

• The water turns into water vapour.

• The water vapour leaves the rivers, lakes or oceans and rises into the sky.

• This water vapour collects in the sky in the

form of clouds.

• This is known as evaporation.

Condensation• Water vapour in the clouds cools down and becomes water

again.

• This is called condensation.

Precipitation

• Precipitation occurs when water in the air changes from water vapour to the liquid form (water)

• The air cannot hold it anymore and the clouds get heavy.

• Water falls back to the Earth in the form of rain or snow.

• This is called precipitation.

Collection• Water falls back to Earth in the form of

rain or snow.• If it falls on the land, the water will soak

into the Earth and becomes a part of the ‘ground water’.• The rain or snow may also fall back in the

oceans, lakes or rivers.• From the oceans or lakes, water

evaporates into the sky again and the cycle continues.

When evaporation, condensation, precipitation and collection happens together, it is known as the WATER CYCLE.

This cycle goes on and on and on…
