Expert Answer:

Zinc is a reactive element. As a result, it attracts most of the air and moisture to itself to form zinc oxide and zinc hydroxide. Upon reacting with the carbon dioxide present in the air, this compound converts into zinc carbonate--a strong and impermeable substance that does not allow more moisture or air to interact with its underlying layers. Therefore it is used in plating iron objects.
Due to the formation if a layer of zinc carbonate corrosion of zinc also stops.
