Water impacts The hydrologic cycle describes the movement of water from one reservoir to another in the hydrosphere. According to figure 11.1 in chapter 11 of our book the hydrologic cycle works like this: First solar energy causes water to evaporate from the ocean, moving water into the atmosphere. Second the evaporated water from the ocean condenses into the clouds. Third the water collected in the clouds will fall back to land or to the ocean aw precipitation, either, rain, hail, or snow. Fourth some of the water returns back to the atmosphere by evaporation and transpiration. Fifth some of the water infiltrates the ground, where it joins the ground water reservoir and may eventually be locked up in the lithosphere in the form of hydrous minerals. Lastly some if the moisture flows back to the sea as surface run-off, while a small amount is captured by the biosphere. The ground reservoir is just one of many places that water can be kept. The largest reservoir for water is the oceans, which holds 97.5 percent of Earth’s water. Some of the other reservoirs include the atmosphere, lakes, rivers, soils, glaciers, and snowfields. What causes the hydrologic cycle to continue from day to day? The answer would be the sun, because the sun provides the energy needed for evaporation. The reason for the water cycle is so that the Earth does not go dry and that there is continuous water flow every day, one way or
