Answer 2

its really a chemical reaction. take the Statue of Liberty for example. it was originally a bronze colored statue, as time went on the bronze color started turning green from the rain water, and the reactions from the air

But that is not erosion. That is a chemical change caused by oxidation (rust). Erosion removes part of the material, it is a physical change.

Answer 3

Erosion is when something that is already weathered away is transported some where else. E.g Acid rain will wear down certain rocks and then the wind/water will transport it some where else. so it would be neither chemical or physical change.

Erosion is a physical change because it involves the physical breakdown and movement of materials without changing their chemical composition.
