Answer 1: oxygen and carbon in the air :-)
Answer 2: Depends on what type of corrosion you are referring to. Rust and corrosion are typically used interchangeably. Rust is one type of corrosion. Corrosion is essentially the disintegration of a engineered material. Rust is a chemical reaction, but there are other chemical reactions that cause corrosion of steel (typically acids).
Other types of corrosion include fretting, erosion, cavitation, and galvanic reactions.
There are many methods to prevent corrosion. One of the most versatile of prevention solutions is electroless nickel plating. Electroless nickel resists all types of corrosion.

"Rust" or "corrosion."
Corrosion is a chemical reaction; corrosion of iron is the reaction with water in the presence of oxygen. Metals as Pt, Au, Ta, Rh, Ru, etc are less sensible to corrosion.
Rusting - oxidation- corrosion.
Acid Rain.
acid rain destroys man made structures
