According to the Environmental Protection Agency (EPA), which one of the following is the largest source of sulphur dioxide emissions?

Question

(a) Locomotives using fossil fuels
(b) Ships using fossil fuels
(c) Extraction of metals from ores
(d) Power plants using fossil fuels

Answer 1

(d) Power plants using fossil fuels

Explanation:

Power plants that burn fossil fuels, particularly coal, are the largest sources of sulfur dioxide (SO₂) emissions. Sulfur dioxide is produced when fossil fuels containing sulfur are burned. The combustion process in power plants releases a significant amount of sulfur dioxide into the atmosphere, which contributes to air pollution and can lead to acid rain. Therefore, option (d) is the correct answer.
