Hydrologic Cycle Definition of Hydrologic Cycyle: uneding circulation of Earth’s water supply powered by energy from the sun Characteristics: 1.Water Evaporates 2.Water vapor transported upward 3.Water Vapor condenses to form clouds 4. Precipitation 5.Some re-enters atmosphere – Evaporation/Transporation 6.Water Infiltrates or runs off 7.Eventually collects in lakes/oceans 8.Water evaporates “Evapotranspiration”: evaporation and transpiration II.Running Water Characteristics A. Importance 1.Energy-hydroelectric dams 2.Travel-early explorers and city locations 3.Irrigation- 4.Flood Plains (agric)-nutrients v. risk B.Runoff 1. “sheet flow”-initial flow after precipitation, broad sheet of water, doesn’t sink in 2. “infiltration capacity”-will soil allow water to sink in? Amount of water a rock can absorb 3.Infiltration capacity cont… *depends on… b.prior wetness of soil c.texture of soil – porosity of soil or rock d.slope of land e.vegatation cover – plant plants by roads
