Weathering or erosion?
1.Rusted Ice Skates - Iron becoming Iron Oxide, Oxidization


2.Worn Away Rock - Granular Disintigration (or weathering)


3.Worn Away Jeans - (Chemical) Abrasion


4.Worn Away Bark From Tree Weathering


5.Crack In Foundation - Subsidance, its not really erosion or weather


6.Worn Away Shoes - Abrasion


7.Crack In Garage - Freeze - thaw weathering (one cause)








btw weathering is a type of erosion .

Reply:1.Rusted Ice Skates-Metal rusts when wet-Weathering


2.Worn Away Rock-Erosion


3.Worn Away Jeans- washed to many times-old -erosion


4.Worn Away Bark From Tree-Erosion


5.Crack In Foundation-the ground settling- Erosion


6.Worn Away Shoes-concrete wears down shoes-Friction


7.Crack In Garage-Same as #5
Reply:Abrasion is not chemical unless it is done with a chemical. In the case of jeans it would be physical.








Weathering is the breakdown of rocks, soils and minerals by physical or chemical means.





Erosion is the movement and displacement of weathered particles.





They are NOT the same.
