The type of weathering responsible for the green patina that forms on the copper skin of the Statue of Liberty is oxidation.
The type of weathering responsible for the green patina that forms on the copper skin of the Statue of Liberty is oxidation. To understand this, let's break down the process step by step:
1. Identify the primary material: In this case, the primary material is copper, which is exposed to the elements.
2. Understand oxidation: Oxidation is a chemical reaction that occurs when a substance comes into contact with oxygen. Copper, when exposed to air and moisture over time, undergoes oxidation. This means that the copper reacts with the oxygen in the air, forming a new substance on the surface.
3. Formation of the patina: When copper oxidizes, it forms a layer of copper oxide on its surface. This copper oxide layer gradually weathers and transforms into a greenish compound called copper carbonate. This is what creates the characteristic green patina seen on the Statue of Liberty.
Therefore, the correct answer is oxidation.
