erosion Flashcards
erosion
Erosion is the action of surface processes that removes soil, rock, or dissolved material from one location on the Earth’s crust and then transports it to another location where it is deposited.
weathering
Weathering is the breaking down of rocks, soils and minerals as well as wood and artificial materials through contact with water, atmospheric gases, and biological organisms.
water cycle
The water cycle, also known as the hydrologic cycle or the hydrological cycle, is a biogeochemical cycle that describes the continuous movement of water on,
evaporation
Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase.
condensation
Condensation is the change of the state of matter from the gas phase into the liquid phase, and is the reverse of vaporization. The word most often refers to the water cycle.
precipitation
In meteorology, precipitation is any product of the condensation of atmospheric water vapor that falls under gravitational pull from clouds.
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 tributary, or affluent, is a stream or river that flows into a larger stream or main stem river or a lake. A tributary does not flow directly into a sea or ocean.
watershed
an area or ridge of land that separates waters flowing to different rivers, basins, or seas.
continental divide
A continental divide is a naturally occurring boundary or ridge separating a continent ’s river systems. Each river system feeds into a distinct ocean basin, bay, or sea. Continental divides are broad, continent-wide example of drainage divides, sometimes just called divides.
deposition
Deposition is the process in which weathered and knocked rock pieces, sediments, particles and soil are carried by process of erosion to a new place and deposited there. This process transports previously eroded sediments, which, at the loss of enough kinetic energy in the fluid, is deposited, building up layers of sediment.
delta
A delta is a body of sediment deposited at the mouth of a river or stream where it enters an ocean or lake.
floodplain
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
In the wastewater treatment plant, the activated sludge is one of the most employed biological treatment technology,56 which comprises multiple unit operations such as sedimentation (primary and secondary settlers), biological decomposition (including aerobic, anoxic, or anaerobic tanks or similar equipment) and followed by disinfection processes such as chlorination, UV irradiation, or ozonation.
