What is the difference between erosion and corrosion?

Erosion is a chemical reaction between a material and its environment, while corrosion is a physical-mechanical process of material removal.

Erosion is a mechanical process of material removal from a sliding or rolling component, while corrosion is a physical-mechanical process of material removal by flow of wind or water.

Erosion is generally proportional to load and the distance of sliding, while corrosion is not influenced by load or sliding distance.

Erosion is a physical-mechanical process of material removal by flow of wind or water, while corrosion is a chemical reaction between a material and its environment. (correct)
