Work Step by Step
The northeastern United States has been experiencing greater amounts of acid rain in recent years compared to other locations listed. Acid rain is a type of precipitation with a lower pH than normal rainwater due to the presence of sulfur dioxide ($SO_2$) and nitrogen oxides ($NO_x$) in the atmosphere. These pollutants are released from various human activities, such as the burning of fossil fuels, and can be transported long distances by the wind before falling as acid rain.
The northeast region, with its higher population density and industrial activities, tends to have higher emissions of these pollutants, leading to more acid rain deposition.
The answer is (c).
