Question

Which of the following is/are responsible for acid rain?
1. Carbon dioxide
2. Carbon monoxide
3. Propane
4. Nitrous oxide and sulphur dioxide

Answer 1

Correct Answer - Option 4 : Nitrous oxide and sulphur dioxide

The correct answer is Nitrous oxide and sulphur dioxide.

• Acid Rain
  • Acid rain, also called acid precipitation or acid deposition, precipitation possessing a pH of about 5.2 or below primarily produced from the emission of sulfur dioxide (SO2) and nitrogen oxides (NOx; the combination of NO and NO2) from human activities.
  • In acid-sensitive landscapes, acid deposition can reduce the pH of surface waters and lower biodiversity.
  • It weakens trees and increases their susceptibility to damage from other stressors, such as drought, extreme cold, and pests.
  • In acid-sensitive areas, acid rain also depletes the soil of important plant nutrients and buffers.
  • Acid rain contributes to the corrosion of surfaces exposed to air pollution.
  • It is responsible for the deterioration of limestone and marble buildings and monuments.
