Acid Deposition

Although much of the polluting sulphur dioxide and nitrogen oxides are produced through human activity, there are also natural sources of these pollutants. Choose which of the following constitutes such a source.

• photosynthesis

• Respiration done by living organisms

• floods

• volcanoes

The two main acids that contribute to wet deposition are:

• Sulphuric acid (H₂SO₄) and nitric acid (HNO₃)

• Chloric acid (HClO₃) and nitric acid (HNO₃)

• Sulphuric acid (H₂SO₄) and carbonic acid (H₂CO₃)

• Carbonic acid (H₂CO₃) and nitric acid (HNO₃)
