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 |
