GEOG 1111 Study Guide - Midterm Guide: Drainage Basin, Geomorphology, Freezing Rain
Document Summary
Water the major agent of geomorphic change on the earth"s surface. 97. 22% is in the oceans and other saltwater and 3 percent is freshwater. Of all freshwater, 22 percent is groundwater and 28 percent the surface. Of the 78% freshwater that is on the surface, ~99% is in ice & glaciers, and ~1% is in freshwater lakes/ponds, rivers/streams. Basic cycle water moving through the environment from the surface into the atmosphere and then back to the surface. Evapotranspiration state to the gaseous state & rises into the atmosphere. Condensation water vapor is converted back to the liquid state forming clouds, or fog in the air (or dew on the ground. Precipitation water returns to the surface in liquid or solid form as rain, snow, sleet, freezing rain, or hail. Water balance output (usage, evaporation, storage), is important not only for life forms but for geomorphic processes. Fluvial system primarily this refers to "running water" may be permanent or temporary.
