A. chemical weathering by acid rain
Many sculptures throughout the United States and Europe are carved from marble or limestone. When sulfuric acid rain strikes these statues, the reaction of the sulfuric acid with the calcium carbonate yields calcium sulfate and carbonic acid. The carbonic acid further breaks down into water and carbon dioxide.
