Groundwater
Earth Science
| Question | Answer |
|---|---|
| Moving water | Rivers, streams, and springs |
| Standing water | Ponds, lakes, and swamps |
| The water cycle | the movement of water from the oceans and freshwater sources to the air and land and finally back to the oceans |
| Evaporation | the process of water to gas phase |
| Condensation | the process of gas to water. Must be cooled for this to occur |
| Precipitation | water returns to the Earth in the form of rain, snow, sleet, or hail |
| Groundwater | Water that remains in the ground, Eventually flows into the ocean, ome of this returns to the earth through springs |
| Valley (alpine) glaciers | long, narrow glaciers that move downhill between mountain valleys |
| Continental glaciers | thick sheets of ice that covers millions of square km of the earth’s surface, moves slowly in all directions |
| Icebergs | Some are as large as Rhode Island |
| Surface runoff | the water that enters a river or stream after a heavy rain or spring thaw |
| Pore space | the space between particles of soil. More pore space means more water the ground can hold |
| Watershed | a land area where surface runoff drains into a river or a system of rivers and streams |
| Lakes | usually deep depressions in the earth’s crust filled with fresh water |
| Ponds | shallow depressions with fresh water, plants usually throughout |
| Reservoirs | the most frequently used source of fresh water |
| Uses of reservoirs | Prevents flooding, drinking water, generates electricity, Irigation for farms |
| Groundwater | present because the various forms of precipitation do not stop traveling when they hit the ground. Instead it moves slowly downward through pores |
| Permeable layers | material through which water can move quickly |
| Impermeable layers | water cannot get through easily, allows water to accumulate |
| Zone of saturation | the underground region in which all the pores are filled with water |
| Zone of aeration | a drier region in which the pores are filled mostly with air |
| Water table | the boundary between the zone of saturation and aeration, that marks the level below which the ground is saturated |
| Aquiclude | Area of impermeable rock, small area in which water can collect, usually found under an aquifer |
| Aquifer | the layer where the water begins to move sideways through a layer of rock that allows it to pass freely |
| Solvent | a substance in which another substance dissolves |
| Solution | contains two or more substances mixed on the molecular level, one thing must be dissolved |
| Soluble | can be dissolved |
| Insoluble | cannot be dissolved |
| Hard water | contains large amounts of dissolved minerals, especially calcium and magnesium |
| Soft water | The opposite of hard water |
| Point source pollution | oil spills, leaking toxic waste, smokestack emissions; where the source is obvious |
| Non point source pollution | where there is no single point of pollution. Examples: runoff carrying natural and human-made pollutants |
