Which type of weathering is responsible for the green patina that forms on the copper skin of the Statue of Liberty

Answer 1

The green patina that forms on the copper skin of the Statue of Liberty is primarily the result of chemical weathering, specifically a process called oxidation. When copper is exposed to air and moisture, it reacts with oxygen and other compounds, leading to the formation of various copper compounds, including copper carbonate, which gives the patina its characteristic green color. This weathering process helps protect the underlying metal from further corrosion.
