Question

Why is the water cycle important to all life on the earth?

Answer 1

Water cycle includes the circulation of water from the oceans through evaporation and its condensation in the clouds and finally to the land in the form of rain, although the water cycle includes much more aspects than only evaporation and condensation.

Complete answer:
Basically the water cycle is a never ending process in which the water from the oceans evaporates and then condenses in the clouds, then the condensed water falls on land in the form of rain.
The water in the ocean is salty water and we humans cannot drink it, the water that comes in the form of rain is not salty as it evaporates first. Thus the water that we get from rain is more important than we think it is, rain water does not only provide us water that we can drink, but it also does the job to store that water in the ground.
Earth has around 97 percent of water on the surface which is just oceans and seas, thus we cannot drink it. Around only 3 percent of water is drinkable and on top of that, most of that water is underground or is turned into glaciers and ice sheets.
Therefore, we only have around 1 percent of water that we can drink and that water comes from rivers, lakes or other wetland areas. Rain and snowfall helps these rivers and lakes to be filled throughout the year.
Most of the water that rains goes underground and goes back into the ocean, some of it fills rivers and lakes, some turns into snow, some just turns into dew and fog, and only some of it is stored in dams.
Only some of the underground water goes to lakes or rivers, most of it returns to the ocean and thus the cycle needs to be repeated. The fresh water that comes from the rain helps the vegetation and forests to grow. Forests solely rely on rains for their water supply, as they cannot get much from underground.
The lakes and rivers that get filled with rain water and underground water helps wildlife animals to survive as that is their only source of water. Many animals migrate a lot just to get water and thus it makes these lakes and rivers more crucial.
Without the water cycle, stored water will dry out quickly and there will remain no source for fresh and drinkable water for animals, forests and humans. Thus, the water cycle is important not just to us, but to all life on earth.

Note:
Water cycle is easy to understand, but there are a lot more factors that affect it that we usually don’t know about. Climate change is disturbing these kinds of crucial processes which can be the reason for the extinction of many species of animals and plantations. The information given above may vary a little bit.
