GEOG 1220 Midterm: Human Impact Post Midterm Summary
Document Summary
All are rather extensive and reading through this once and simplifying it in the process would be more than enough review for all!!! Pages 249 252, 265 278, and chapter 13: Chapter 12: the hydrologic environment: precipitation, land use, and water resources. All water frozen is in polar ice caps. Hydrologic condition of earth essential to understand life and support system. Most important factor of life = water. Water delivered by atmosphere to land as part of weather. Five natural reservoirs of water: 1) oceans 2) glacial ice caps 3) Glacial ice = largest reservoir for freshwater. The rest are sources that humans and organisms depend on for water supplies. Hydrologic cycle: flow-system characterized by exchanges of water among five major reservoirs. Driven by heat of earth"s absorption of solar radiation. Transpiration also returns water into the atmosphere, when coupled with evaporation. Groundwater released from land through stream and river discharge. Atmosphere exchanges on average every nine days.
