Water cycle

Water cycle

     

  Water cycle is the most important cycle on the earth . Water is the life of Humans  , excluding humans, plants and animals also need water to live. Water cycle help us to maintain the capacity of water on the earth. On the earth there is a 71% water and 29% of land . From 71% of water 97.5% is saline  water and 2.5% being fresh water. Of the fresh water, only 0.3% is in liquid form on the surface that human can drink. So we can understand the the importance of water.

Saline water is used to produce electricity , it contain large amount of salt that's why it can't use for drinking as a resource.

 So now we want to come on our topic water cycle you have learn this in 5th standard that what is water cycle but now we will learn it in the deep:

The process in which water change into water vapour is called as evaporation.

The process by which air get convert into water droplets is called as condensation.

The process in which solid get convert into air without changing in water state is called  sublimation.

In the process  instead of water droplets ,snow come out from the cloud , called precipitation.

The process in which the plants leaves produce water vapour this process is called as transpiration.

By the transpiration of plant water goes up in the atmosphere and form clouds with the help of evaporation. Then clouds run of the snow this snow stuck on the mountain and at the time of sunny weather it get converted into water from long distance water come back in the ocean and plants absorb that water, this goes on & our water cycle form. It's also called a transpiration water cycle.

 By The evaporation ocean water get converted into gaseous state and this air mix in the atmosphere and form a cloud ,by the precipitation the snow runs from the cloud and stuck on the mountain again  in  the sunny weather is converted into water and come back into ocean,again this ocean water turn into vapours and come down as snow and water droplets and water cycle take place.
