Weathering and Soil
the process that breaks down rock through chemical changes
chemical weathering
a wind-formed deposit made of fine particles of clay and silt
loess
a landform made of sediment that is deposited where a river flows into an ocean or lake
delta
time in Earth’s history during which glaciers covered large parts of the surface
Ice Age
the process in which sediment is laid down in new locations
deposition
the type of weathering in which rock is physically broken into smaller pieces
mechanical weathering
the process by which wind removes surface materials
deflation
water that flows over the ground surface rather than soaking into the ground
runoff
any large mass of ice that moves slowly over land
glacier
a glacier that covers much of a continent or large island
continental glacier
the geological principle that the same geologic processes that operate today operated in the past to change Earth’s surface
uniformitarianism
small, solid pieces of material that come from rocks or the remains of organisms; earth materials deposited by erosion
sediment
a channel through which water is continually flowing downhill
Stream
the sediments deposited directly by a glacier
till
the movement of water and sediment down a beach caused by waves coming in to shore at an angle
Longshore Drift
the process by which water, ice, wind, and gravity moves weathered particles of rock and soil
erosion
any one of the several processes by which gravity moves sediment downhill
mass movement
a wide, sloping deposit of sediment formed where a stream leaves a mountain range
Alluvial Fan
a long, narrow glacier that forms when snow and ice build up in a mountain valley
Valley Glacier
The glacier will change this alley in the future by making it wider and causing more valleys to form around it.
Erosion affects the Earth’s surface by wearing down and carrying away rock particles. Erosion involves the removal of rock particles by wind, water, ice, and gravity.
The kinds of mass movement that could happen quickly are mudslides and landslides.
The two features that result from deposition by groundwater are caves that produce stalactite and stalagmite.
What are three landforms formed by wave deposition?
The three landforms formed by wave deposition are sea stacks, cliffs, and sea arches.
Niagara Falls rocks will more than likely erode and push the falls back and the area around the falls will have to build their attraction areas further away from the falls.
