Changes in the Land

• ByJennifer B.

2
Definitions

• Deposition-The process by which sediment is
  placed in another area by wind, plants, and
  water.
• Erosion-The laying down of sediment.

3
Forces-Water

• In the background,there is a wave that is eroding
  the beach.This force is called water.It is the
  main force that shapes earths surface.

4
Forces-Rain

• Rain is another kind of water erosion.
• Rain erodes by hitting the ground.Each drop is
  like its own pond which can expand.

5
Ice

• Water flows into cracks,then it freezes over
  night.The ice then cracks which cause the rock to
  crack with it.

6
Forces-Wind

• Tornadoes are a kind of wind force.
• They form mostly in deserts.

7
Wind-Gale winds

• Gale winds create landforms called sand dunes,
  which are mounds of sand usually in deserts.

8
Wind-Hurricanes

• Hurricanes are similar to tornadoes, but they
  carry water.
• Hurricanes form near beaches instead of in the
  middle of the desert.

9
Terms-result of deposits by rivers

• Alluvial fans-Similar to deltas that come out
  from mountain valleys.
• Delta-An end of a river that is fan shaped and
  flows into an ocean

10
Terms-result of erosion by rivers

• Oxbow lakes-Meanders which get cut off from a
  river.
• Meander-A curve in a river where eroded sediment
  is.
• Waterfall-A river that flows over a hard layer of
  rock and under it is soft rock that wears away
  first.
