fresh flow of water
water ways
| Question | Answer |
|---|---|
| erosion | the processes by which wind, water, ice , and gravity transport soil and sediment from one location to another |
| water cycle | the continuos movement of water from the ocean to the atmosphere and back down to the ocean |
| water system | where smaller streams join bigger ones and hey join bigger ones and so on |
| watershed | the area of land the is drained by water system |
| divide | the boundary between drainage areas that have streams that flow in opposite directions |
| channel | the path that streams follow |
| discharge | the amount of water a streams carries in a given amount of time |
| gradient | the measure of change in elevation over a certain distance |
| load | the material a stream carries |
| bed load | large materials like pebbles and boulders |
| suspended load | small rocks and soil which makes the stream muddy |
| dissolved load | material that has been dissolved in the water |
| youthful river | erodes its channels deeper rather than wider steep ( high gradient) very few tributaries many falls and rapids |
| mature river | erodes it channels wider rather than deeper not very steep (low gradient) fed by many tributaries few falls and rapids |
| old river | wide flat land ( low gradient) large meanders |
| rejuvenated river | found where the the land is raised by tectonic activity has step like formations called terraces |
| meanders | the curves in rivers |
| deposition | the process in which materials is laid down |
| placer deposit | where heavy minerals are sometimes deposited at places in a river where the current slows down |
| delta | a fan-shaped mass of material deposited at the mouth of a stream |
| alluvial fan | a fan-shaped mass of mistrial deposited by stream when the slope of land decreases sharply |
| floodplain | an area along a river that forms from sediment deposited when the river overflows its banks |
| dam | a barrier that can redirect the flow of water |
| levee | a buildup of sediment deposited along a channel or river |
| water table | the upper surface of groundwater |
| zone of aeration | the portion of ground above the water table where the rain water passes through |
| zone of saturation | the portion of ground below the water table where the rain water is collected |
| porosity | the percentage of the total volume of a rock or sediment that consist of open space |
| permeable | the ability of a rock or sediment to let fluids pass through it open space, or pores |
| impermeable | a rock that stops the flow of water |
| groundwater | the water located below the earths surface |
| aquifer | a body of rock or sediment that stores groundwater and allows the flow of groundwater |
| recharge zone | an area in which water travels downwards from the ground to become part of an aquifer |
| spring | an opening where water flow out of the ground |
| well | a human made hole that is deeper than the level of a water table |
| artesian spring | a spring whose water flews from a crack in the cap rock over the aquifer |
| cap rock | the impermeable layer of rock above an aquifer |
| dry well | a well that did not reach the water table |
| stalactites | sharp icicle figures that hang on the ceiling of caves |
| stalagmites | sharp icicle figures that are found on the ground of caves |
| dripstone column | when stalactites and stalagmites join to make column's |
| sinkhole | a circular hole formed when the roof of a cave collapses |
| point-source pollution | pollution that comes from a specific site |
| nonpoint-source pollution | pollution that comes from many sources not just on specific site |
| dissolved oxygen | oxygen that is dissolved in water |
| thermal pollution | an increase in water temp. |
| sewage treatment plant | a facility that cleans the waist material found in water that comes from sewages and drains |
| primary treatment | the process from winch most/all sludge is removed from the sewage tank |
| secondary treatment | where the chemicals and bacteria are removed to make per water |
| septic tank | a tank that separates solid waste from liquids and that has bacteria to break down the solid waste |
