The word is "oxidation", which in the case of copper is a three-step process where the copper oxidizes to copper oxide, then to cuprous or cupric sulfide, and then to copper carbonate. Copper carbonate is the green colored copper or patina that forms over time. The old name for this green patina is "verdigris".

Is copper turning green in the air physical change?
The reason that copper turns green is the same reason the metal rusts, oxidization. Both metal and copper oxidize when exposed to oxygen and this is a natural process. Copper that is exposed to the outside environment is more likely to turn green and that is why copper vases and decorative pieces in gardens are often green. Copper is a metal that does not react with water (H2O), but the oxygen of the air will react slowly at room temperature to form a layer of brown-black copper oxide on copper metal which looks like green sometimes...
Will iron oxide turn copper green?
No, iron oxide will not turn copper green. The green patina on copper is typically the result of oxidation due to exposure to air and moisture, which forms copper carbonate or copper chloride compounds. Iron oxide itself does not have this effect on copper.
