SSC MTS EXAM

Detailed explanation-1: -Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.

Detailed explanation-2: -Acid rain comes in many forms: rain, snow, sleet, hail, and fog (wet deposition), and as acid particles, aerosols, and gases (dry deposition). Acid deposition forms when sulfur dioxide (SO2) and nitrogen oxides (NOx) combine with moisture in the atmosphere to produce sulfuric acid and nitric acid.

Detailed explanation-3: -Nitrogen oxides are critical components of photochemical smog. They produce the yellowish-brown colour of the smog. In poorly ventilated situations, indoor domestic appliances such as gas stoves and gas or wood heaters can be significant sources of nitrogen oxides.
