The gradual eating up of metals by 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

Answer 2

Explanation:

Corrosion is a natural process that converts a refined metal into a more chemically stable form such as oxide, hydroxide, or sulfide. It is the gradual destruction of materials by chemical and/or electrochemical reaction with their environment.
