Term | Definition |
Erosion | move or carry |
Weathering | break down |
Deposition | settles or drops |
sediment | pieces of rock |
What are the 5 agents of erosion? | wind water glacier (ice) gravity wave action |
factors that can affect erosion | Development-clear land and build things Agriculture-good and bad farming techniques Mining-strip mining Plants-increase\decrease vegetation Climate-hurricanes, storms, etc.. |
What is mass movement? | pieces of rock\soil\sediment on a slope that can be easily moved by gravity |
what is the main cause of mass movement? | gravity |
A ____________ occurs when loose soil and rock separate from bedrock below | Landslide |
A ____________ occurs after large\heavy rains. This causes gravity to pull down mud. | Mudflow\ Mudslide |
A ______ is when a large piece of rock breaks off and falls because of gravity | slump |
Gravity causes weathered particles to slowly, steadily move downhill | creep |
This is the major agent of erosion and is constantly building up and tearing down earths surface | water |
_______, gully, stream, river | rill |
rill, gully,_______, river | stream |
rill, gully, stream,________ | river |
'V' shaped valley | steep slopes that erode rapidly due to a fast moving river |
river erodes rock, so it falls and forms sharp drop off | waterfall |
loop like bends through erode rock & sediment | meander |
long narrow island that forms along coast | barrier island |
large mass of ice that moves slowly over land AKA- river of ice | glacier |
sediment deposited by glaciers. | moraine |
Built to reduce wave energy. However, it makes beach disappear and is ugly | sea wall |
soil conservation techniques | no till-contour plowing-crop rotation-cover crops- wind breaks- terracing |
return the land to its original state or better | Reclamation |
any type of water that moves across land because it is not absorbed by soil | runoff |
smaller stream\river flows into larger stream\river | tributary |
land that contains all rivers\streams | watershed\drainage basin (they are the same thing) |
FOR GLACIERS ONLY: what is this called when rock pieces freeze to sides and bottom of glacier | plucking |
what landform can wind create | sand dunes |
why are coastlines and deserts more affected by wind erosion | no\little vegitation |
