Why does iron rust quicker near the sea?

Question

I'm doing an assessment task on rust and i want to know why people who live by the sea have a problem with rust.

Answer 1

all the salt thats in the water gets carried around, which scrapes and wears down the iron.

Answer 2

Rust is the result of a chemical reaction between iron and the oxygen in water.

Metal rusts more quickly when salt is present because salt is a better conductor ie: the electrons in the metal pass quicker through the salt to get to the oxygen.  Therefore the rusting happens faster!

Hope this helps!

Answer 3

Iron was completely sensitive with salts that  to get rust that like much quick in near salty seas.

Answer 4

The Salt causes the rusting.  

Answer 5

salt in the air

Answer 6

salt i believe is naturally corosive

however i think it has more to do with the fact that for rust to occur there must be both air and water.

near the sea there is more water around even as vapor in the air that is why iron rusts quicker near the sea... the salt in the air would also add some minimal impact in speeding up the process of rusting or corrosion.
