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 movement of water between earth and the atmosphere
evaporation
when water changes from a liquid to a gas
condensation
when water turn into a liquid from a gas
percipitation
when water falls back to the surface
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
a drainage basin
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
deposition
The accumulation or laying down of matter by a natural process, as in the laying down of sediments in streams or rivers
delta
Unlike other landforms affected by water current, a delta is not mainly created because of erosion of land surface caused by the force of wind and water
floodplain
an area of low-lying ground adjacent to a river, formed mainly of river sediments and subject to flooding.
water table
The water table is an underground boundary between the soil surface and the area where groundwater saturates spaces between sediments and cracks in rock
sewage treatment plant
Sewage treatment is a type of wastewater treatment which aims to remove contaminants from sewage to produce an effluent that is suitable for discharge to the surrounding environment or an intended reuse application,
septic tank
A septic tank is an underground chamber made of concrete, fiberglass, or plastic through which domestic wastewater flows for basic treatment. Settling and anaerobic processes reduce solids and organics
sea stack
a column of rock standing in the sea, remaining after erosion of cliffs.
sea arches
Sea arches are a spectacular phenomena created by Mother Nature with a little help from oceans
sea cave
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 terrace
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,
headlands
a narrow piece of land that projects from a coastline into the sea
beach
a pebbly or sandy shore, especially by the ocean between high- and low-water marks.
glaciers
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 the name for all material of glacial origin found anywhere on land or at sea, including sediment and large rocks
till
Till or glacial till is unsorted glacial sediment. Till is derived from the erosion and entrainment of material by the moving ice of a glacier
stratified drift
predominantly unconsolidated, sorted sediment composed of layers of sand, gravel, silt or clay deposited by meltwaters from glaciers.
