Question

Quizplus · Accepted Answer

Acid deposition is primarily caused by sulfur and nitrogen oxides emitted from human activities such as burning fossil fuels and industrial processes. These gases can react with water vapor in the atmosphere to form sulfuric and nitric acid, which can then be deposited onto the Earth's surface through precipitation (acid rain) or dry deposition.
