Which term means rain containing nitric and sulfuric acids?

• A. Acid rain
• B. ATP
• C. Nonrenewable resource
• D. Renewable resource

Answer: (A)

Rain that carries nitric and sulfuric acids is called acid rain. It forms when pollutants like sulfur dioxide and nitrogen oxides from burning fossil fuels rise into the atmosphere and react with water and oxygen to create sulfuric acid and nitric acid. The dissolved acids lower the rain’s pH, making it more acidic than normal rain. This can harm aquatic ecosystems, leach nutrients from soils, and corrode buildings and statues made of calcareous stone. The other terms don’t describe rain composition: ATP is an energy molecule in cells, and renewable/nonrenewable resources refer to types of energy or materials, not to precipitation chemistry.
