<P> The water cycle , also known as the hydrological cycle or the hydrologic cycle , describes the continuous movement of water on , above and below the surface of the Earth . The mass of water on Earth remains fairly constant over time but the partitioning of the water into the major reservoirs of ice , fresh water , saline water and atmospheric water is variable depending on a wide range of climatic variables . The water moves from one reservoir to another , such as from river to ocean , or from the ocean to the atmosphere , by the physical processes of evaporation , condensation , precipitation , infiltration , surface runoff , and subsurface flow . In doing so , the water goes through different forms : liquid , solid ( ice ) and vapor . </P>
