Unit 7 TJA

What is a Primary Pollutant?

• forms in the atmosphere after chemical reactions 

• An air pollutant emitted directly from a source.

• made up of particles (tiny pieces) of solids or liquids that are in the air

•  a layer in the atmosphere in which air temperature increases with height.

What is a secondary pollutant?

• forms in the atmosphere after chemical reactions

• a mixture of pollutants that are formed when nitrogen oxides and volatile organic compounds (VOCs) react to sunlight, creating a brown haze above cities.

• a layer in the atmosphere in which air temperature increases with height.

• made up of particles (tiny pieces) of solids or liquids that are in the air

what is photochemical smog?

• a mixture of pollutants that are formed when nitrogen oxides and volatile organic compounds (VOCs) react to sunlight, creating a brown haze above cities.

• a layer in the atmosphere in which air temperature increases with height.

• made up of particles (tiny pieces) of solids or liquids that are in the air

• An air pollutant emitted directly from a source.

What is Thermal Inversion?

• a mixture of pollutants that are formed when nitrogen oxides and volatile organic compounds (VOCs) react to sunlight, creating a brown haze above cities.

• An air pollutant emitted directly from a source.

• a layer in the atmosphere in which air temperature increases with height.

• made up of particles (tiny pieces) of solids or liquids that are in the air

What is Particulate Matter?

• a layer in the atmosphere in which air temperature increases with height.

• a mixture of pollutants that are formed when nitrogen oxides and volatile organic compounds (VOCs) react to sunlight, creating a brown haze above cities

• forms in the atmosphere after chemical reactions

• made up of particles (tiny pieces) of solids or liquids that are in the air
