Document Summary
Surface water: water accessible on the earth"s surface including oceans, lakes, streams and wetlands- this water is lost through evaporation, replenished through precipitation and snow melt and small amounts of surface water recharge groundwater. Ground water: water located below the earth"s surface, in soil or rock spaces. Aquifer: a geological formation containing large quantities of usable groundwater- recharged slowly by infiltration of surface water and removed by natural springs and human withdrawal. Urban sprawl can be measured by low residential density- population and housing density, distant separation of homes- over 1 acre plots, lack of city centers- more strip malls, and difficult street networks- more need for cars and longer transportation. Haber-bosch process: making synthetic fertilizer from atmospheric nitrogen leads to increases in crop yields which benefits the rich farmers. Erosion: the action of surface process which removes soil and rock from one location on earth"s crust to then transport it.
