25
Q

air pollution (indoors and outdoors)

A

introduction of chemicals, particulate matter, or microorganisms into the air
-can be harmful to plants, animals, and humans

26
Q

coal and oil pollution

A

-coal combustion: releases most pollutants (CO2)
-Oil is slightly less in releasing pollutants

27
Q

sulfur dioxide (SO2)

A

-corrosive gas released by combustion of fuels originating with coal and oil

28
Q

nitrogen oxides

A

results from pollution reacting with nitrogen in the atmosphere; mostly from motor vehicles; can lead to acid rain

29
Q

carbon dioxide (CO2)

A

-colorless, odorless gas formed during COMPLETE combustion of matter; greenhouse gas

30
Q

carbon monoxide (CO)

A

-colorless odorless gas formed during INCOMPLETE combustion of matter; can be a dangerous indoor pollutant

31
Q

particulate matter

A

-solid/liquid particles suspended in the air; comes from combustion of wood, manure, coal, oil, gas; aka “soot particles” (smog and or haze)

32
Q

Thermal inversions

A

atmospheric condition in which a warm layer of air at mid-altitudes covers a layer of colder air

Normal conditions (bottom to top): warm air, cold air, cold air
Thermal inversions (bottom to top): cold air, warmer air (inversion layer), cold air
