Erosion
2
Erosion transports weathered rock material.
3
What are some ways that weathered material can be transported?
4
Erosion by Gravity Rocks and other materials, especially on steep slopes, are pulled toward the center of Earth by gravity.
5
Here, the weathering occurs by frost wedging
The erosion occurs by gravity
6
Erosion by Gravity Slump Mud Slide Rock Slide
7
Erosion by Wind When air moves, it picks up loose material and transports it to other places.
8
Erosion by Wind Sandstorm Dust Storm Strong Winds
9
Erosion by Water When water moves, it picks up loose material and transports it to other places.
10
Erosion by Water Rivers or Streams Rain Runoff Flooding
11

12
Animations of Erosion by Water
Animation of sediments being transported Animation of erosion by a waterfall Animation of the formation of an arch Study Jams: Weathering and Erosion
13
Erosion by Ice When a glacier moves, it picks up loose material and transports it to other places.
14
Images of how Glaciers erode rock

15
Turn to an elbow partner and describe examples of erosion you have observed.
With a different elbow partner, discuss the difference between Weathering and Erosion.
16
Weathering and Erosion are two very different processes that tend to act sequentially.
17
Weathering is the result of the physical and chemical changes of rock and mineral material; the resulting products might or might not be transported.
