1. WeatheringAndErosion Weathering And Erosion

2. The Different Types of Weathering There are many different types of weathering. Here are a few: Oxidation Root Pry Exfoliation Frost Action Wind Abrasion Frost Action Acid Rain

3. This rock is red because of the oxidation of iron in the sediment when the rock was being formed.

4. Root Pry The tree is growing in the rock and soon the rock will break apart because of the tree roots.

5. This is a picture of the Half Dome. The rock is peeling away from the mountain in layers just like an onion. This is exfoliation.

6. Frost Action or ice wedging slowly breaks up this sedimentary rock into unusual shapes.

7. These rocks have been blasted by wind and sand causing them to become rounded. WIND ABRASION

8. Acid Rain 1908 to 1969 Acid rain has eaten away this limestone statue.

9. Erosion There are many kinds of Erosion. Here are a few: Wave Action Running Water Landslides Avalanche Glaciers Slump Creep Rock Fall Mud Flow

10. Wave action is when waves hit the rocks and pieces of rock break off.

11. In this picture the running water eroded the sides of this canyon and created the V-shaped valleys.

12. This is a picture of a landslide. A type of mass wasting.

13. In this picture the land has slumped into the road below.

14. This is a diagram of creep. The hillside slowly slips over many years from temperature or water.

15. This is a picture of an avalanche. It is similar to a landslide with ice and snow instead of rock.

16. This is a picture of a glacier which carves out a U-shaped valley where it flows dragging rocks and boulders along the way.
