Acid rain contributes to soil erosion. Acid rain can be caused by

the release of pollutants into the atmosphere, especially sulfur dioxide (SO2) and nitrogen oxides (NOx), from burning fossil fuels such as coal and oil in power plants, factories, and vehicles. These pollutants combine with water vapor in the air to form sulfuric acid and nitric acid, which then fall to the ground as acid rain. When this acidic rainwater comes into contact with soil, it can dissolve minerals and nutrients, making the soil less fertile and susceptible to erosion. Additionally, the acidic nature of the rain can directly erode the soil particles, leading to soil erosion and degradation.
