Erosion and Deposition 1
This is the definition of erosion.
What is the removal of weathered material from one place to another?
Layered sediment deposited by streams of water that flow from a melting glacier
Outwash
Glaciers cause erosion by doing this to land, rock and sediment (address what glaciers do to each of land, rock and sediment in your response.)
What is scraping over the land like giant bulldozers, carving through rock and pushing sediment in front of them?
Erosion caused by a glacier creates this
u-shaped valley
pile of windblown sand
dune
What is it often begins in the mountains and runs swiftly down steep slopes, and erodes the bottom of the channel more than the sides forming v-shaped valleys; flows more slowly, and the slower water erodes the sides of the stream channel more than the bottom and develops curves; moves slowly as it reaches flat land, and meanders are likely to form?
mound or ridge of unsorted sediment
moraine
the flat, wide area of land along a river
flood plain
A wide, sloping deposit of sediment formed where a stream leaves a mountain range
Alluvial Fan
a crumbly, windblown deposit of silt and clay
loess
This is the laying down or settling of weathered materials by moving water, wind, glaciers, or gravity.
What is deposition?
mixture of various sizes of sediment deposited by a glacier
till
loop-like bend in the course of a river
meander
A landform made of sediment that is deposited where a river flows into an ocean or lake
Delta
formed by mineral deposits in caves
stalactites
What is poorly, moderately, and well-sorted sediment?
The slowest mass wasting event
creep
A meander that has been cut off from the river
oxbow lake
What is built to prevent beach erosion?
groin
The grinding away of rock by other rock particles carried in water, ice, or wind
Abrasion
Over time, how will erosion and deposition affect a mountain range and the valleys contained within it?
Erosion will gradually wear away the mountain.
Deposition will fill valleys with sediment.
meander
c-shaped curve in a stream
What are three features that result from depostion along a river?
Alluvial fans, river deltas, and soil on flood plains
What is it moves parallel to the shoreline; sand moves back and forth perpendicularly to the shoreline with the waves (coming in at an angle, moving out perpendicularly) and also parallel to the shore with the current, moving the sand diagonally down the shoreline, depositing sediment in some places and eroding it in others?
what type of erosion forms limestone caves?
groundwater erosion
