oxidation
Weathering effects on statues include erosion from wind and water, chemical reactions with pollutants in the air, biological growth such as moss or lichen, and physical stress from temperature changes. Over time, these factors can lead to the deterioration of the statue's surface, affecting its appearance and structural integrity.
Igneous rock becomes sediment due to exposure to chemical and mechanical weathering at or near the surface.

Because acid is acidic, obviously it burns/dissolves the statue quicker than normal rain. that, and the acid rain stays in the rough surfaces of the carvings, whereas it just drops off smooth surfaces, leaving only a small trail of acid
The rate of chemical weathering typically increases when a rock becomes more mechanically weathered. Mechanical weathering creates more surface area for chemical reactions to occur, allowing water and chemicals to penetrate deeper into the rock and accelerate the breakdown process.
Acrylic or latex paint is recommended for concrete statues as they adhere well to the surface and provide durability and weather resistance.
Acrylic paint is a good choice for painting plaster statues because it adheres well to the surface and dries quickly.
Acrylic or latex paint is recommended for painting concrete statues as they adhere well to the surface and provide durability and weather resistance.
The rate of chemical weathering generally increases when a rock becomes more mechanically weathered. This is because mechanical weathering creates more surface area on the rock, providing more pathways for chemical reactions to occur. Additionally, cracks and fractures formed during mechanical weathering allow water and air to penetrate deeper into the rock, accelerating chemical weathering processes.
The tarnishing of a silver surface is a chemical change. This is because the silver undergoes a reaction with sulfur compounds in the air, forming silver sulfide. This chemical reaction results in a change in the composition and properties of the silver surface.
