Which among the following is the major cause of acid rain?
|A) Carbon dioxide||B) Carbon monoxide|
|C) Nitrogen oxides||D) Oxygen|
Answer: C) Nitrogen oxides
The major cause of acid rain is the emission of sulfur dioxide (SO2) and nitrogen oxides (NOx) into the atmosphere, which react with water, oxygen, and other chemicals to form sulfuric acid and nitric acid. These acids then fall to the ground as acid rain, which can cause damage to crops, forests, bodies of water, and buildings. Sulfur dioxide and nitrogen oxides are primarily produced by human activities such as burning fossil fuels for energy, transportation, and industrial processes.
