• Coal burning power plants
• Medical waste
• Runoff from thermometer factories

Which of the six types of air pollution monitored by the EPA. Is formed from incomplete combustion?

• CO₂

• CO

• SO₂

• O₃

A secondary pollutant __________________________.

• forms in the stratosphere

• is transformed by sunlight, water, or other elements in the atmosphere

• cannot be directly tracked to its source

• forms primarily from incomplete combustion

Which is a source of Sulfur Dioxide found in nature?

• forest fires

• lightning

• plant emissions

• volcano

Thermal inversions _________________________.

• increase the rate of smog formation

• trap high concentrations of pollution at ground level

• result in increased levels of acid deposition

• reduce the negative effects of VOC's

Acid deposition (rain) forms as a result of ______________ accumulating in the atmosphere.

• nitrogen oxides and photochemical smog

• carbon monoxide and VOC's

• sulfur dioxide and VOC's

• nitrogen oxides and sulfur dioxides

Which method is used to reduce emissions of Nitrogen Oxides?

• installation of catalytic converters

• increased temperature of combustion

• the use of calcium carbonate to absorb the emissions

• the use of fluidized bed combustion
