Sulfur and nitrogen oxides in the atmosphere lead to a form of air pollution called deposition.

The statement regarding sulfur and nitrogen oxides in the atmosphere contributing to deposition is accurate. These pollutants are major contributors to acid rain, which is a form of atmospheric deposition.

1. Sources of Pollution: Sulfur oxides (SOx) and nitrogen oxides (NOx) are primarily released into the atmosphere through the burning of fossil fuels from vehicles, industrial operations, and power plants.

2. Chemical Reactions: Once in the atmosphere, these gases react with water vapor, oxygen, and other trace chemicals. For example:

   • Sulfur dioxide (SO₂) can react with water to form sulfurous acid (H₂SO₃), and further oxidation can produce sulfuric acid (H₂SO₄).
   • Nitrogen oxides can form nitric acid (HNO₃) through similar reactions.

3. Effects of Deposition: When these acids are deposited back to the Earth's surface, primarily through precipitation, they lead to a variety of environmental issues, including soil acidification, damage to aquatic systems, and harm to vegetation. Acid rain can also erode buildings and monuments, particularly those made from limestone and marble.

4. Mitigation Efforts: To combat this form of pollution, regulations such as the Clean Air Act have been established in many countries, aiming to reduce the emissions of SOx and NOx.

In summary, sulfur and nitrogen oxides contribute to acid deposition, posing serious environmental threats that necessitate ongoing regulation and cleanup efforts.
