Question

How does air pollution impact chemical weathering? (1 point)

Answer 1

Air pollution can significantly accelerate chemical weathering by increasing the concentration of acidic components in the atmosphere, such as sulfur dioxide (SO₂) and nitrogen oxides (NOx). When these pollutants combine with water vapor, they form acids like sulfuric and nitric acids, which can fall as acid rain. This acidic precipitation enhances the breakdown of minerals in rocks and soil, leading to faster weathering processes. Additionally, pollutants can alter the chemical composition of soil and water, impacting the rates of various weathering reactions.
