erosion Flashcards
what is erosion
it moves sediments from 1 place to another
what is deposition
eroded materials get dropped
relate gravity gradient discharge and load
higher gradient= higher gravity
higher discharge = higher load
describe what happens to sediment as streams slow
slow moving streams have smaller particles and less erosive energy
describe the role of stream erosion and deposition in building landform
it moves sediments creating areas like canyons and allluval fans
describe effects of erpsion by groundwater
caves form
sinkholes
sataligtes
floodplain
deposited sediment on a flat area
delta
streams deposit loads into a fan shaped pattern
alluvial fan
fan shape deposit that forms on dry land
groundwater
water located within the rocks below Earth’s surface
shoreline
where land and water meet
beach
an area of shoreline made up of deposited material
sandbar
underwater or exposed ridge of sand gravelly or shells
barrier island
long narrow is
