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 water cycle shows the continuous movement of water within the Earth and atmosphere.
evaporation
Evaporation is the process by which water changes from a liquid to a gas or vapor.
condensation
water which collects as droplets on a cold surface when humid air is in contact with it.
precipitation
the action or process of precipitating a substance from a solution.
surface runoff
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
the area of land where all of the water that drains off of it goes into the same place—a river, stream or lake.
continental divide
Continental divides separate one drainage basin from another.
deposition
the action of deposing someone, especially a monarch.
delta
the fourth letter of the Greek alphabet ( Δ, δ ), transliterated as ‘d’.
floodplain
an area of low-lying ground adjacent to a river, formed mainly of river sediments and subject to flooding.
water table
an underground boundary between the soil surface and the area where groundwater saturates spaces between sediments and cracks in rock.
sewage treatment plants
Sewage treatment is a type of wastewater treatment which aims to remove contaminants from sewage to produce an effluent that is suitable for discharge
septic tank
A septic tank is an underground chamber made of concrete, fiberglass, or plastic through which domestic wastewater flows for basic treatment.
sea stacks
of rock in the sea near a coast, formed by wave erosion.
sea arches
Sea arches are a spectacular phenomena created by Mother Nature with a little help from oceans.
sea caves
a type of cave formed primarily by the wave action of the sea.
wave-cut terraces
A gently sloping coastal feature at the seaward or lakeward edge of a wave-cut platform, constructed by sediment brought by rivers or drifted along the shore or across the platform and deposited in the deeper water beyond.
headlands
a coastal landform, a point of land usually high and often with a sheer drop, that extends into a body of water.
beach
a pebbly or sandy shore, especially by the ocean between high- and low-water marks.
glacier
A glacier is a persistent body of dense ice that is constantly moving under its own weight.
glacial drift
A general term applied to all rock material (clay, silt, sand, gravel, boulders) transported by a glacier and deposited directly by or from the ice, or by running water emanating from a glacier.
till
up to (the point in time or the event mentioned); until.
stratified drift
predominantly unconsolidated, sorted sediment composed of layers of sand, gravel, silt or clay deposited by meltwaters from glaciers.
