Erosion and Depsition
Erosion is the movement of materials away from one place and deposition is the placing of the materials in a new place by wind, water or gravity.
Gravity is the main force in erosion like a flowing river cutting into the rocks to form a canyon or a landslide pulling rocks and dirt downhill.
Fast rivers carry more sediment.
First paragraphpg. 276
Wave ErosionSand on the beach is created by waves which are a source of erosion and deposition.
The constant action of waves is a major source of erosion along shorelines.
Harbors and inlets form when some areas erode more quickly than others.
Deltas are a place where heavy sediments are deposited when a river meets an ocean.
Rocks are ground to sediment under moving glaciers.
Roots of trees can be exposed because the flowing water removed the sand that used to cover them.
First paragraphpg. 278
Wind and Field Erosion
The wind can move dust, dirt, or sand from one place to another.
Wind erosion can cause problems on farms so farmers try to prevent wind erosion by planting trees along the edges of fields to block some of the wind.
Large, loose deposits of sand are called sand dunes.
