NEET BIOLOGY

Detailed explanation-1: -Vehicle emissions, fuel oils and natural gas to heat homes, by-products of manufacturing and power generation, particularly coal-fueled power plants, and fumes from chemical production are the primary sources of human-made air pollution.

Detailed explanation-2: -Power plants release the majority of sulfur dioxide and much of the nitrogen oxides when they burn fossil fuels, such as coal, to produce electricity. In addition, the exhaust from cars, trucks, and buses releases nitrogen oxides and sulfur dioxide into the air. These pollutants cause acid rain.

Detailed explanation-3: -Acid rain can be formed by natural causes, such as volcanic eruptions. More commonly, however, acid rain is due to human activities. Burning fossil fuels, manufacturing, oil refineries, electricity generation, and vehicles all release sulfur and nitrogen oxides into the atmosphere.
