In three to five sentences, explain how acid rain is formed and how it impacts humans.

Answer 1

Acid rain is formed when sulfur dioxide (SO2) and nitrogen oxides (NOx) are released into the atmosphere, primarily from burning fossil fuels, and then react with water vapor, oxygen, and other chemicals to form sulfuric and nitric acids. These acids can then fall to the ground in precipitation, thereby lowering the pH of rainwater. The impacts on humans can be significant, as acid rain can damage crops, forests, and waterways, leading to reduced agricultural yields and negatively affecting drinking water sources. Additionally, it can corrode buildings and infrastructure, increasing maintenance costs and posing health risks through the contamination of air and water.
