Question

acid rain is a form of pollution that is harmful to lakes. which of the following sources of pollution is a major contributor to the creation of acid rain?
a. coal - fired power generating stations
b. primary sewage - treatment plants
c. sanitary landfill sites
d. animal feedlots

Explanation:

Acid rain is mainly caused by the emission of sulfur dioxide (SO₂) and nitrogen oxides (NOₓ). Coal - fired power generating stations burn coal, which contains sulfur. When coal is burned, sulfur is oxidized to SO₂, and this SO₂ is a major contributor to the formation of acid rain. Primary sewage - treatment plants mainly deal with sewage and do not emit significant amounts of SO₂ or NOₓ related to acid rain. Sanitary landfill sites mainly produce methane and other waste - related gases, not the main pollutants for acid rain. Animal feedlots mainly produce animal waste and related pollutants, not the key pollutants for acid rain. So coal - fired power generating stations are a major contributor to acid rain.

Answer:

A. Coal - fired power generating stations
