Oxidation

Not quite so simple as oxidation. If oxidation were the only reaction occurring copper would turn black (CuO2) or less likely red (Cu0) and then black. The reaction turning copper green (verdigris as seen on the coppered roofs of churches etc) is due to partial oxidation followed by reaction with carbon dioxide to form the water insoluble blue/green copper carbonate
which slowly builds to give such a beautiful green patina to the metal surface.

The reaction is called oxidation
Basically copper react with the air and forms a basic copper carbonate compound called patina.

Oxidation! Can you imagine that the statue of liberty was once shiny brown copper!

For your further edification: rusting is also a two-step process. Rust is simply iron (III) oxide.
First, iron (Fe) reacts with water (H20) and oxygen (O2) to produce iron (II) hydroxide (Fe(OH)2). The iron hydroxide warmed by sunlight produces iron (III) oxide (Fe2O3) and water.
