erosion Flashcards
Erosion
the process of eroding or being eroded by wind, water, or other natural agents.
Weathering
the process of wearing or being worn by long exposure to the atmosphere.
water cycle
the cycle of processes by which water circulates between the earth’s oceans, atmosphere, and land, involving precipitation as rain and snow, drainage in streams and rivers, and return to the atmosphere by evaporation and transpiration.
Evaporation
the process of turning from liquid into vapor.
Condensation
water which collects as droplets on a cold surface when humid air is in contact with it.
precipitation
Precipitation is any liquid or frozen water that forms in the atmosphere and falls back to the Earth.
surface runoff
Surface runoff is the flow of water occurring on the ground surface when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil.
tributary
a river or stream flowing into a larger river or lake.
watershed
an area or ridge of land that separates waters flowing to different rivers, basins, or seas.
continental divide
A continental divide is a drainage divide on a continent such that the drainage basin on one side of the divide feeds into one ocean or sea, and the basin on the other side either feeds into a different ocean or sea, or else is endorheic, not connected to the open sea.
deposistion
a formal statement that someone who has promised to tell the truth makes so that the statement can be used in court.
delta
Landform
floodpain
an area of low-lying ground adjacent to a river, formed mainly of river sediments and subject to flooding.
water table
the level below which the ground is saturated with water.
sewage treatment plants
The treatment of sewage is part of the field of sanitation
septic tank
a tank, typically underground, in which sewage is collected and allowed to decompose through bacterial activity before draining by means of a leaching field.
sea stacks
a column of rock standing in the sea, remaining after erosion of cliffs.
sea arches
Sea arches. Another spectacular type of erosional landform is the sea arch, which forms as the result of different rates of erosion typically due to the varied resistance of bedrock.
sea caves
A sea cave, also known as a littoral cave, is a type of cave formed primarily by the wave action of the sea. The primary process involved is erosion.
wave-cut Terraces
A wave-cut platform, shore platform, coastal bench, or wave-cut cliff is the narrow flat area often found at the base of a sea cliff or along the shoreline of a lake, bay, or sea that was created by erosion.
Headlands
a narrow piece of land that projects from a coastline into the sea.
Beach
a strip of land covered with sand, pebbles, or small stones at the edge of a body of water, especially by the ocean between high- and low-water marks.
glacier
a slowly moving mass or river of ice formed by the accumulation and compaction of snow on mountains or near the poles.
glacial drift
In geology, drift is a name for all sediment transported by a glacier and deposited directly by or from the ice, or by glacial meltwater.
till
the net soil translocation on the hillslope due to tillage operations, expressed in units of volume, mass, or depth per unit width of tillage.
stratified drift
predominantly sorted sediment laid down by or in meltwater from glaciers and includes sand, gravel, silt, and clay arranged in layers.
