The Water Cycle


What is the Water Cycle? 
Have you ever wondered about how the rain falls? Well if you have, heres everything you need to know about the water cycle. The water cycle goes round and round every day of your life, so it never stops. If we did not have the water cycle, we would not exist along with animals and insects. 
Firstly, the water from an ocean, lake, river or plant evaporates up into the air, which then the clouds are formed  this is called condensation. After that the rain is stored in the cloud, this is precipitation. When the cloud snows or rains on top of a mountain, the snow melts and becomes water and travels down the mountain through streams and flows into a lake, then the ground water seeps from under the ground and back into the sea. Then the process starts again.
Evaporation is an essential part of the water cycle. This is important because  this is the first part of the cycle and if we didn’t have it the water would never make it to the sky to form a cloud which means there would be no rain.The sun extracts water from oceans, lakes and moisture in the ground and evaporates into a cloud.
Condensation is the formation of liquid drops of water from water vapour. It is the process which creates clouds, and so is necessary for rain and snow formation as well.
 Precipitation  is very important because it plays a very big part in the water cycle, if we didn’t have it we would not have rain. Precipitation is when rain, snow, sleet (any form of water) falls from clouds in the sky. 
Collection is when the rain falls from the clouds and the mountain collects it into the streams and then the water flows down to the river or sea. 
To conclude, the water cycle is a non stop cycle  that is very important to us, animals, insects and the environment. If we didn’t have it we would not be able to survive.The main parts are Evaporation, Condensation, Precipitation and Collection.
