The wet magmas rise towards the Earth's surface. Water may also evaporate from lakes, rivers, and the nearby Pacific Ocean to form clouds. Precipitation falls from the clouds. Some water from rain and melting snow infiltrates into the subsurface to form groundwater. Other precipitation runs off into lakes and rivers.
Rivers drain into the Pacific Ocean.
The ocean water may then be incorporated into ocean sediments that may be eventually subducted. The cycle starts over. Subduction of wet sediments Small amounts of water moving from the mantle to the crust Ice, including glaciers, melting Streams and other surface waters move Groundwater also moves The terms evaporation and transpiration may be combined to form the term evapotranspiration . The amount of surface water in an area depends on the amount of annual precipitation, runoff and evapotranspiration. That is, instead of infiltrating and becoming available for crops and other plants, the rain largely runs off, enters streams and leaves the area.
