NGSS.HS-PS4-4

One 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
