Term
Particulates
Definition
Solid particles that are microscopic in size and are suspended in the air
Term
Atmospehric Pressure
Definition
The force applied to the earth's surface by the weight of the overlying atmosphere
Term
Temperature Inversion
Definition
Increase of temperature with height in the atmospehere
Term
Air Pollutant
Definition
Airborne particles and gases that occur in concentrations that endanger health and well-being of organisms, or disrupts the orderly functioning of the environment
Term
Primary Air Pollutant
Definition
A chemical that has been added directly to the air by natural events or human activities and occurs in harmful concentrations
Term
Secondary Air Pollutant
Definition
A harmful chemical formed in the atmosphere by reacting with normal air components or other air pollutants
Term
Photochemical Smog
Definition
A mixture of certain primary and secondary pollutants formed when they interact with sunlight
Term
CFC's
Definition
Chloroflurocarbons. Most serious threat to the ozone shield. known as freon
Term
HCFC's
Definition
Hydrochloroflurocarbons. Major current subsitute for CFC's. Break down in trophosphere so dont make it to stratosphere. Temorary replacement
Term
Greenhouse Effect
Definition
The physical process whereby shortwave, solar energy is transmitted relatively easily through the atmosphere, while longwave, terrestrial energy is partially absorbed, the re-radiated back toward the earth's surface by certain atmospheric gases
Term
Feedbacks
Definition
If one thing happens, it influences the occurence of something else; positive feedbacks are those which will encourage or enhance greenhouse warming, and negative feedbacks are those which will discourage or reduce greenhouse warming
Term
Non-variable Gases
Definition
Proportion in atmosphere does not change over time or space (nitrogen, oxygen, argon, trace gases)
Term
Variable Gases
Definition
proportions do change over time/space (water vapor, ozone, carbon dioxide)
Term
Good Ozone
Definition
Stratosphere
Term
Bad Ozone
Definition
Surface
Term
Formaldehyde
Definition
Most commonly found toxin indoors
Term
Asbestos
Definition
Added to materials because of its heat resistance, strength, chemical inertess, and ability to be woven into fabric. *Not harmful unless fibers disturbed
Term
Cigarette Smoke
Definition
4500 poisonous compounds
Term
Radon
Definition
a radioactive, colorless, tasteless, ordorless gas. produced from breakdown of uranium
