Answer 1

Corrosion: Corrosion is the process of deterioration of a substance due to chemical, electrochemical or other reactions that take place on the surface of that substance.

Rusting:

Rust is an iron oxide, a usually red oxide formed by the redox reaction of iron and oxygen in the presence of water or air moisture. Several forms of rust are distinguishable both visually and by spectroscopy, and form under different circumstances. Rust consists of hydrated iron(III) oxides Fe2O.
