CHEMICAL WEATHERING
DEF: EROSION OF SOMETHING BECAUSE OF CHEMICAL REACTIONS. CHANGES THE SUBSTANCE OF THE OBJECT.
CHEMICAL WEATHERING
- Changes substance of object
- Appears in forms of rust on metal
- Looks like it's changing the color of the rock
Definition: the erosion or disintegration or rock because of chemical reactions. Changes the substance of the rock.
WATER EROSION
DEF:the removal of surface material by water from the Earth's crust and transportation of the eroded materials from the point of removal.
WATER ERIOSION
- Pick up materials and move is somewhere else
- Rivers, beaches are good examples
- Does not change what the object is made of
WIND EROSION
DEF: THE EROSION, TRANSPORTATION AND DEPOSITION OF TOPSOIL BY WIND
WIND EROSION
- Doesn't change what the substance is made of
- Only changes the size
- Sand doons and the rock in this background is a good example
GLACIAL EROSION
DEF: OF SOIL OR ROCK FROM ONE POINT TO ANOTHER BY THE ACTION OF THE MOVING ICE OF A GLACIER. ALSO KNOWN AS ICE EROSIONDE
GLACIAL EROSION
- Doesn't change the substance the rock is made of
- Only changes and deforms the ground
- Happens over a long period of time
