Show answer & explanation

Correct answer: D

Explanation:

Acid rain is mainly caused by the emission of sulfur dioxide (SO2) and nitrogen oxides (NOx) into the atmosphere.

  • How it forms: These gases react with water, oxygen, and other chemicals in the atmosphere to form sulfuric acid (H2SO4) and nitric acid (HNO3).

  • Main sources: Burning of fossil fuels in power plants, industrial processes, and vehicle emissions release SO2 and NOx.

  • Effects: Acid rain lowers the pH of soils and water bodies, damages plants and aquatic life, and corrodes buildings and monuments.
