Polluted urban air may be more acidic leading to more rapid chemical weathering.

Question

Quizplus · Accepted Answer

Polluted urban air often contains chemicals such as sulfur dioxide and nitrogen oxides which can react with water in the atmosphere to form acid rain. When acid rain falls on rocks and soil, it can accelerate the process of chemical weathering, breaking down the minerals faster than they would under normal conditions. This can have impacts on soil fertility, plant growth, and water quality, among other things.
