Write a brief paragraph explaining the rusting process (why rusting occurs)
Rusting occurs when Iron is exposed to moisture and oxygen. When iron has water or is damp and then the oxygen from the air goes into the water, The surface of the iron reacts with the oxygen mixed in water, it creates a thing called iron oxide. Iron oxide mixers with the water and creates hydrated iron oxide which is the red stuff we call rust.

How could you prevent something from rusting?
To help prevent iron or metal from rusting you can paint the places that are exposed to oxygen or moisture most people do this to bikes and cars. Another way to prevent rust is to add a layer of oil or grease some people oil their bicycle chains which slows done the process of rusting. To prevent rusting you can also use a sacrificial protection called Galvanizing. This method works when iron gets covered in zinc. The zinc is a self healing metal that is very effective and will last longer.
