Explain why acid rain, smog, ocean acidification, and global warming are indirect results of air pollution.
They are indirect results because air pollutants can change or react in the atmosphere or water before causing harm. Sulfur dioxide and nitrogen oxides can form acids that lead to acid rain, and pollutants can react in sunlight to create smog. Carbon dioxide can dissolve in the ocean and lower its pH, while greenhouse gases trap heat and contribute to global warming.
