Document Summary
Hydrologic cycle describes the cycling, movement and storage of water through the other spheres in a closed loop: 97% of water is in the oceans, 2. 8% is in the ice caps. Evaporation is the flux of water from a free water state to the atmosphere: removal of heat from the surface (latent heat effect) through absorption cools the surface. Evapotranspiration is the sum of evaporation and transpiration: the rate is controlled by wind speed, available energy, temperature, relative humidity, and soil saturation level. Condensation is the phase change of water from a gas to a liquid when an air mass is saturated at its dew point temperature. Precipitation is the flux of water from the atmosphere to the earth"s surface. Run off is the flux of water through the lithosphere to water bodies: moves across land in three types of flux. Overland flow: across the surface because the soil is saturated, or the land is impermeable.
