The water on earth changes forms from solid to liquid and to gas as it moves from one reservoir to another. It moves from the earth to the air and back to the earth repeatedly.

Water cycle is a continuous phase where water evaporates, travels into the air and becomes part of a cloud. As clouds moves over mountains, the water vapor condenses and falls down to earth as precipitation and freezes. Snow will fall and fill in the underground then create an overflowing water in rivers and lakes, and then evaporates again.
