Question

what is water cycle?

Answer 1

The continuous interchange of the forms of water on Earth is called the water cycle or hydrogical cycle.
It involves  the three different processes of evaporation, condensation and precipitation.
Water from the surface of the Earth evaporates on heating and changes into water vapour. Approximately 80% of water vapour is obtained from the oceans, and the remaining 20% from inland water and vegetation.
The water vapour is carried up in the air, where it cools. On cooling, water vapour in the atmosphere condenses, changes back to its liquid state and forms clouds. 
When cloud particles get too heavy to remain suspended in the air, they fall back to the Earth as precipitation. Precipitation occurs in a variety of forms- hail, rain , snow , sleet etc.

Hope it helps!!

Answer 2

Answer:

Water Cycle:-

• Water cycle is a process in which water of the oceans or seas evaporate and the water vapour rises up.
• As the water vapour reaches up, they cool down and form clouds. When this process goes on continusly there are lots of water vapour in the sky.
• When the clouds become heavy enough, they fall down back to earth in the form of rain, snow, etc. which we call as precipitation.
• This process is continuous, as through the precipitation water again fill up seas and oceans again it get evaporated and then again clouds and precipitation.
• This is a non-stop continuous process which we call as Water Cycle.
