Expert Answer:

The gradual eating up of metals by the action of air, moisture or a chemical reaction (such as an acid) on their surface is called corrosion.

The most commonly seen example of corrosion of metals is rusting of iron i.e the formation of a brown flaky substance on iron objects on exposure to moist air.
