| Question | Answer |
|---|---|
| Surface water | lakes, rivers, streams, percolates through ground to form groundwater, less than one percent of all water on Earth |
| Fresh water | water has been diverted to areas to make them habitable, used to manufacture, dispose of waste, and generate power, mostly frozen in ice caps |
| Groundwater | difficult to clean (deep in ground, pollutants cling to materials, recycling takes thousands of years), |
| Water treatment process | Chlorine kills bacteria |
| Shortage of freshwater | prevented by conserving water, education, new ways to produce freshwater |
| Water conservation | use low flow showerheads and take short showers |
| Point source | Pollution from a single source |
| Nonpoint source | agricultural runoff |
| Pathogen | disease causing bacteria, viruses, and parasitic worms |
| Watershed | large area of land drained by a river, largest in US is Mississippi River |
| Large cities | get water from rivers and lakes |
| Phosphates | may cause fish to suffocate and die |
| Plastic trash | eaten by turtles, strangle birds, entangle sea mammals |
| Dams | less built because of environmental considerations, create energy, change land behind because of a change in flow |
| Water pollution | magnifies over time in food chains |
| Thermal pollution | decreases oxygen |
| Reservoir | artificial lake created by a dam |
| Aquifer | underground rock formation that holds water |
| Recharge zone | area of land through which water percolates to be stored as groundwater |
| Desalination | removes salt from salt water |
| Biomagnification | accumulation of pollutants at successive levels of the food chain |
| Eutrophication | nutrients increase in a lake causing oxygen levels to decrease |
| Water cycle | continuous movement of water between the Earth and atmosphere |
| Ogallala Aquifer | supplies 1/3 of all the groundwater in the US |
| Well | hole that is dug to reach groundwater |
| Industrial water use | highest in Europe and America |
| Potable | water that is safe to drink |
| Xeriscaping | landscaping with minimal water use |
| Water Pollution | introduction of chemical, physical, or biological agents into water that degrade the quality |
| Ocean Pollution | mainly from land activities |
