the moisture helps algae the green to grow
The color that copper turns when it oxidizes is called verdigris. It is a greenish-blue patina that forms on the surface of copper over time due to exposure to air and moisture.
The color green that aged copper turns into is called patina. It is a natural blue-green tarnish that forms on the surface of copper when exposed to air and moisture over time.
The reason your skin turns green is because the item's base metal is copper, even though it may be plated with gold or silver which will wear off and expose the copper based metal underneath.
Copper is a metal that turns green when oxidized.
The color change of copper to green is a chemical change. This is due to the formation of a green patina on the surface of the copper, typically caused by oxidation reactions with the air and moisture.
That green stuff that shows up on copper is called verdigris, and is also known as patina. In addition to making your penny green, it's also what makes the copper Statue of Liberty look green!The process by which verdigris is made is called oxidation. Most of the time, when copper oxidizes, it turns dark brown, like most pennies you see. When saltwater is added (like in somebody's sweaty pocket) the copper turns green instead.

Copper typically turns green when it oxidizes, forming a patina known as verdigris. This greenish layer is created as a result of the chemical reaction between copper and moisture in the air.
Yes, copper typically forms a greenish patina when exposed to the environment for a period of time. This is due to the oxidation process, which creates copper carbonate on the surface of the metal, giving it a green color.
A copper bracelet turns green due to a process called oxidation. When copper reacts with oxygen and moisture in the air, it forms a greenish layer of copper oxide on its surface, known as patina. This patina acts as a protective coating that helps prevent further corrosion of the copper.
Oxygen turns copper green.
Copper turns green when it oxidizes because of the formation of a greenish layer of copper oxide on its surface.
