What two gases are the primary causes of acid depostion?

The primary gases responsible for acid deposition are sulfur dioxide (SO₂) and nitrogen oxides (NOx). These gases are released into the atmosphere through industrial processes, vehicle emissions, and combustion of fossil fuels. Once in the atmosphere, they can react with water, oxygen, and other chemicals to form sulfuric and nitric acids, which fall to the ground as acid rain or other forms of acid deposition. This process can lead to environmental damage, affecting ecosystems, soil, and water quality.
