How is "acid rain" defined?

• A. Rain that occurs during thunderstorms
• B. Precipitation containing high levels of sulfuric or nitric acids, often due to air pollution
• C. Rain that is simply lower in temperature
• D. Rain that carries beneficial nutrients for plants

Answer: (B)

Acid rain is defined as precipitation that contains high levels of sulfuric or nitric acids, often as a result of air pollution. This phenomenon occurs when sulfur dioxide and nitrogen oxides, released into the atmosphere from sources like vehicle emissions and industrial processes, react with water vapor, oxygen, and other chemicals to form acidic compounds. These compounds can then fall to the ground as rain (or other forms of precipitation), leading to environmental issues, including harm to aquatic ecosystems, soil degradation, and damage to buildings and monuments. The other definitions do not accurately capture what acid rain is. Rain during thunderstorms does not inherently carry acidic properties, nor does temperature alone define rainfall characteristics. Additionally, while rain can provide beneficial nutrients when it's clean and unpolluted, acid rain is detrimental due to its elevated acidity levels and the associated negative impacts it has on the environment. Thus, the correct definition emphasizes the link between acid rain and its formation due to pollution.
