• Arsenic
• Radon
• Asbestos
• Carbon Monoxide

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

High levels of photochemical smog are due to

NGSS.HS-PS1-5

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
