Question

Quizplus · Accepted Answer

Acid rain is formed when pollutants (usually sulfur dioxide and nitrogen oxides) are emitted into the atmosphere, travel considerable distances, and react with the water, oxygen, and other chemicals in the air to form acidic compounds, which then fall to the ground. These pollutants are often emitted by industrial facilities and power plants, which tend to be concentrated in specific areas. Therefore, acid rain occurrence is closely associated with the middle to long distance wind flows, as the polluted air may travel far from its source before it reacts with the atmosphere and forms acid rain. Urban areas, large population concentrations, and modern transportation systems may contribute to the emission of pollutants, but they are not directly related to the geography of acid rain occurrence.
