Copper reacts with oxygen, carbon dioxide and sulfur dioxide to form compounds called a "patina", which can very loosely be thought of as a sort of rust. These compounds have a greenish cast to them.
The best example of patina is the Statue of Liberty. It's made of copper and when new it looked like a shiny penny. Exposure to the atmosphere for over a century has caused the familiar green color.
Sprite can turn green when it comes into contact with copper from pipes or coins due to a chemical reaction that forms copper compounds. These copper compounds can change the appearance of the drink, giving it a green tint. It is safe to drink, but it is recommended to avoid consuming drinks that have changed color as a precaution.
Acid in the rain reacted with the copper to turn it green. That is why there is sometimes green on pennies. Acid in the rain reacted with the copper to turn it 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.
For copper or some copper alloys coins the coating is hydrated copper carbonate.
The pennies turn green because they are open to the air, because they contain copper, and because copper turns green when oxidized.
To make copper turn green, you can expose it to air and moisture over time. This process, called oxidation, forms a greenish layer of copper carbonate on the surface of the copper.
Becasue of oxidation!
oxygen.
Copper turns green because of sulfur pollution in the air, forming copper sulfide.
The brown copper(II) chloride absorb water and form the green dihydrate.
Pewter turns it black, Copper does turn your skin green though.
No, hematite doesn't contain copper so your skin will not turn green
