Which of the following results in the fall of acid rain?
Answer Details
The presence of certain gases and particles in the air can contribute to the formation of acid rain. Acid rain occurs when rainwater mixes with these gases and particles, forming acidic solutions that fall to the ground. Out of the given options, the oxides of sulfur are known to be the main contributor to acid rain. When sulfur dioxide (SO2) and nitrogen oxides (NOx) are released into the atmosphere, they react with water, oxygen, and other chemicals to form sulfuric acid and nitric acid, respectively. These acids then fall to the ground in the form of acid rain, damaging forests, lakes, and other ecosystems. Therefore, the correct answer is "Oxides of sulphur."
