The water cycle is extremely important process because it ensures the availability of water for all for all living organisms as regulates weather patterns on our planet. The water on our planet continuously circulates between land and atmosphere due to water cycle.

The water cycle is very important, as water is very important to us. Approximately three-fourths of the Earth is covered with water, mainly salt water. Of this water, approximately one percent is the fresh water on which we depend. The fresh water that we use and its continuous replacement is a result of the water cycle. Earth has limited amount of fresh water and if water that evaporate never return back to earth, life would not be possible.

Also flow of water over and beneath the Earth is a key component of the cycling of other biogeochemicals.                                                                                                                                   K                                                                                                                                        Kindly post each query separately.
