What process is exacerbated by the presence of sulfur dioxide in the atmosphere?

The presence of sulfur dioxide in the atmosphere is primarily associated with the formation of acid rain. This process occurs when sulfur dioxide (SO₂) is emitted into the atmosphere, often from burning fossil fuels and industrial processes. Once in the atmosphere, sulfur dioxide can react with water vapor, oxygen, and other chemicals to form sulfuric acid (H₂SO₄) and other acidic compounds.

When these acids precipitate, they fall to the ground as acid rain. This acidic precipitation can harm aquatic ecosystems, damage vegetation, and corrode buildings and infrastructure. The phenomenon of acid rain illustrates the direct environmental impact of sulfur dioxide emissions, emphasizing the need for regulation and control of these pollutants to protect the environment.

In contrast, soil erosion, ozone layer destruction, and global warming involve different chemical processes and elements that do not directly involve sulfur dioxide in the same way. While these processes are critical environmental issues, they do not primarily arise from the presence of sulfur dioxide as the formation of acid rain does.
