Quizplus · Accepted Answer

Acid deposition, also known as acid rain, is a result of human activities such as burning fossil fuels and releasing sulfur dioxide and nitrogen oxide into the atmosphere. These substances react with water vapor and sunlight to form sulfuric acid and nitric acid, which then fall to the ground as acid rain. This acid rain releases toxic ions of cadmium and aluminum into the soils, making it difficult for trees to absorb essential nutrients and causing them to weaken.
