Have you ever thought of why does it train? If it rains so heavy li sometimes then where does all the extra water go? The truth is that the amount of water which is present in the earth is quite limited and therefore in case of excessive rain that water is taken from the earth itself and gets converted and given back to the earth in the form of rain and this entire process is known as the water cycle and it ensures that the amount of water on Earth is always balanced and approximately the same.
The process of water cycle has been going on through thousands of years each and every year. The water cycle consists of many different processes which we would be explaining below.
This is the first stage of the water cycle in which the water actually evaporates from the water bodies. You might notice that oceans and seas are actually a vast source of water and waters from the rivers as well as the streams is collected into the oceans. Does the water go anywhere else from the oceans? You might think upon this and the answer to that is yes because some of the water which is contained in the ocean bodies actually is evaporated because of the sunlight. As the temperature over the ocean increases due to extensive sunlight some of the water is evaporated because of the high temperature.
This water then turns into the forms of vapours which arise high into the air because of their less weight. As the quantity of this vapour increases they actually form clouds and again more and more vapour is collected in these clouds but since clouds are actually cooler than the hot air which is outside the vapour which is collected into the clouds again turns into the form of water and is stored in the cloud and therefore when you look at the clouds you would find that some of the clouds are actually darker than the others because the grey colour clouds are having a lot of water inside them better as the normal white clouds do not have a lot of water inside them. This all depends on the heat over the oceans because of the heat of the sun over the ocean is more than there would be more and more vapour which would be collected and therefore the clouds would have more water content whereas if the temperature of the air over the oceans is low then only a small amount of water evaporates and therefore the clouds do not have a large amount of water content.
The heat of the sun again depends on the revolution of the earth around the sun because when the earth is closer to the Sun than the heat is more and the vapour is also more whereas during the winters when the earth is far away from the sun the heat is less and therefore the vapours are also less. This constitutes a process of evaporation.
We gave you a small idea of the process of condensation above because after the formation of clouds if more water vapour is collected in the clouds then it cools down to form missed and water which comes down in the form of rain. This process is actually not as fast as it seems. There are a lot of variations due to which this cycle may not get completed because it is a really reliant on the temperature which is present over the oceans and this is dependent on the sun. After the process of condensation is complete we would be moving on to the process of precipitation.
This is the step where the water vapour inside the clouds actually turns into water and comes down in the form of rain because as the clouds more over the land was the temperature decreases and this relates to the conversion of water vapour back into water and this water cannot be held by the clouds for a long period of time and this water comes down in the form of rain but this water directly does not return to the oceans because the rain may occur anywhere and at different locations from the ocean and therefore there is one more step in the entire water cycle which is known as collection as well. When this water comes down it may come down in the form of snow or it may come down in the form of rain.
As explained about the rain or the fall of snow can operate different geographical locations and therefore they do not directly return to the ocean from where the water was evaporated and this gives rise to another important step of the water cycle which is known as collection.
When the water falls over the hilly areas are over some other areas then you might notice that it turns into streams and many of such streams form the rivers which again meet the oceans.
With that being said not all of this water is contained in the rivers because some of this water goes into the fresh water storage as well which is consumed by human beings and other living beings and after the usage of human beings and other living beings it is again return to the oceans in the form of wastewater. This completes the entire process of water cycle because when the water reaches the oceans the entire cycle begins itself again in the form of evaporation.
The water cycle is very vital to ensure that human beings as well as other living beings are able to lead a normal life because our life is greatly dependent on the water sources and these water sources are again greatly dependent on the water cycle that is the entire process of providing water to human beings. The ocean water is not directly consumable but when it goes through the process of water cycle it is very much consumable and that is the reason that water cycle is actually very important to our living being.
