Document Summary
How much of earth"s water is fresh, hydrology i. Study of the movements and characteristics of water on and under earth"s surface i: four percent of earth"s water is fresh, residence time. And underground water (1%: sketch the simplified water cycle, evaporation i, precipitation (water vapor) Runoff: water flowing over the surface of the earth, rivers, water enters the rock or soil through joints or small pores ii. Infiltration: cycle continues, other factors affecting the cycle i. Sublimation: the water can get trapped in a frozen state, like a glacier, transformation of a solid (ice) directly into a gas (water vapor, the release of water vapor from plants. Transpiration ii: explain why reservoirs reduce flooding, reservoirs i. Store water and reduce flooding: not all the water that comes in goes out. In dry periods we have low input and low output.
