Answer:

It forms a barrier that prevents corrosive substances from reaching the underlying steel or iron. The zinc serves as a sacrificial anode so that even if the coating is scratched, the exposed steel will still be protected by the remaining zinc. The zinc protects its base metal by corroding before iron.

Answer:

It protects it from corrosion.

Step-by-step explanation:

Zinc protects iron and steel from the relentless forces of corrosion. Galvanizing iron and steel by dipping them in molten zinc creates an alloy that can, in the right environmental conditions, protect the iron or steel beneath it for 100 years or more.
