Expert Answer:

Corrosion of iron is known as rusting.
Rusting is the slow oxidation of iron by atmospheric oxygen in the presence of water.
Iron when comes in contact with moist air reacts to give rust which is a brown powder mainly hydrated iron (III) oxide (Fe2O3.xH2O).
4Fe + 3O2 + 2xH2O → 2Fe2O3.xH2O
Rust is a soft powdery material, whcih easily falls off from the surface ofiron and hence it firther exposes the inner part of the iron metal to air and moisture for further rusting. Thus, iron gets damaged.
