Step-by-step explanation:
The statement is true. The surface color or texture on metal caused by aging is called a patina. It is a thin layer that forms on the surface of the metal due to exposure to air, moisture, and other environmental factors over time.
For example, when copper or bronze reacts with oxygen in the air, it forms a green patina known as verdigris. This can be seen on the Statue of Liberty, which is made of copper.
Patina can also be intentionally induced on metal objects as a decorative element or to protect the metal from further corrosion.
