Which statement correctly relates acid rain and carbonate rocks?
Answer and explanation
Correct answer: Acid rain can react with carbonates and slowly erode them
Carbonate rocks such as limestone contain carbonate ions, which react with acids. In a simplified reaction, an acid and a carbonate produce a salt, water, and carbon dioxide; for example, carbonate minerals can slowly dissolve in acidic rainwater. Repeated dissolution weakens and erodes the rock surface. Therefore option A is correct. Acid rain does not strengthen all carbonates, and its effects are not limited to iron.
