What is acid rain
Accepted Answer
Acid rain is a type of rain that is made more acidic than normal by the presence of certain chemicals, such as sulfur dioxide and nitrogen oxides, in the atmosphere. These chemicals react with water to form acidic compounds, like sulfuric acid and nitric acid, which lower the pH of rain. Acid rain is harmful to the environment, as it can damage trees, aquatic life, and buildings.
