Question

Acid rain is harmful to

• A. Plants
• B. Animals
• C. Buildings
• D. All of these

Answer 1

The correct option is D All of these

Sulfur dioxide (SO${}_2$) and nitrogen oxides (NO${}_2$) are emitted into the atmosphere and transported by the wind and air currents. The SO${}_2$ and NO${}_2$ react with water, oxygen, and other chemicals to form sulfuric and nitric acids. These then mix with water and other materials before falling to the ground in the form of acid rain. When this acid deposits on land or water it results in acidity harming organisms. It also causes corrosion of building materials and paints. Thus the correct answer is option D.
