The Different Types of WeatheringThere are many different types of weathering.
Here are a few:
• Oxidation
• Root Pry
• Exfoliation
• Frost Action
• Wind Abrasion
• Frost action
• Acid Rain
Page 3
This rock is red because of the oxidation of iron in the sediment when
the rock was being formed.
Page 4
Root Pry
The tree is growing in the rock and soon the rock will break apart because of the tree
roots.
Page 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.
Page 6
Frost Action or ice wedging slowly breaks up this sedimentary rock into unusual
shapes.
Page 7
These rocks have been blasted by wind and sand causing them to
become rounded.

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

Erosion
There are many kinds of Erosion.
Here are a few:
• Wave Action
• Running Water
• Landslides
• Avalanche
•Glaciers
• Slump
•Creep
• Rock Fall
• Mud Flow
Page 10
Wave action is when waves hit the rocks and pieces of rock break off.
Page 11
In this picture the running water eroded the sides of this canyon and created the V-
shaped valleys.
Page 12
This is a picture of a landslide. A type of mass
wasting.
Page 13
In this picture the land has slumped
into the road below.
Page 14
This is a diagram of creep. The hillside slowly slips over many
years from temperature or water.
Page 15
This is a picture of an avalanche. It is similar to a landslide with ice and snow
instead of rock.
Page 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.
