pollution in the air. Which choice is NOT a source of outdoor air

pollution?

• car emissions

• factory emissions

• radon gas

• volcanic eruptions

Which types of gases most commonly combine with water to form acid precipitation?

• carbon oxides and nitrogen oxides

• carbon oxides and sulfur oxides

• nitrogen oxides and sulfur oxides

• ozone and carbon monoxide

Order the following to explain how acid rain forms.

• Sulfur oxides and nitrogen oxides are given off by factories

  and vehicles as products of burning fossil fuels. These gases rise into the

  atmosphere.

• These oxides combine with the water in the clouds to

  form sulfuric and nitric acids.

• The acid precipitation falls to Earth as

  precipitation, such as snow or rain.
