(26 cards)

Montreal Protocol

Front

is an international treaty - the first in the history of the United Nations to be universally ratified - that guides the gradual elimination & production of ozone-depleting substances.

Back

atmosphere

Front

the envelope of gases surrounding the earth or another planet.(99% composed of nitrogen & oxygen)

Back

Kigali Amendment

Front

international commitment to phase out HFC emissions by at least 80% by 2047

Back

Chlorofluorocarbons (CFCs)

Front

man made chemicals that were commonly used in refrigerators from the 1930s to the 1990s

Back

secondary pollutants

Front

forms in the air(or water) through chemical reactions among primary pollutants ex:salt

Back

particulate matter

Front

aerosols that are suspended in the atmosphere -dust, black carbon, ash

Back

Stratosphere

Front

thermal layer of earth's surface that is above the troposphere -temp increases as you get away from earth's surface

Back

Volatile Organic Compounds (VOCs)

Front

highly flammable compounds of hydrogen and carbon that undergo reactions under sunlight

Back

environmental lapse rate (ELR)

Front

the rate of cooling in the troposphere ELR= (3.6f/1000ft)x (height change)

Back

Exosphere

Front

space near earth where molecules are not under the influence of earth's gravitational pull

Back

air pressure

Front

the force exerted by molecule of air against a surface (higher air pressure at sea level, lower air pressure in top peak)

Back

ozone layer

Front

a thin layer of ozone (O3) found in the Stratosphere

Back

fossil fuels

Front

ancient remains of organic material(plants/animals) that over long period of times have been altered by heat & pressure into coal,oil, & natural gases

Back

Troposphere

Front

thermal layer of earth's atmosphere that's closest to earth's surface. -temperature decreases with distance from earth

Back

Aerosols

Front

microscopic droplets and particles that are suspended in the air (solids or liquids)

Back

cloud droplets

Front

microscopic drops of liquid water found in clouds

Back

Mesosphere

Front

thermal layer above the stratosphere -temp gets cooler as you get away from earth surface

Back

Clean Air Act

Front

1st legislation that regulates the amount of atmospheric pollutants

Back

photochemical smog

Front

air pollution that is formed by reactions with sunlight and nitrogen oxides and or VOCs

Back

greenhouse gas

Front

a gas that can absorb & emit thermal energy Ex: water vapor, carbon dioxide, ozone

Back

Ionsphere

Front

layer of earth surface where nitrogen and oxygen are ionized by solar radiation

Back

Thermosphere

Front

The outermost layer of Earth's atmosphere above the mesosphere

Back

primary pollutants

Front

enters the atmosphere (or water) directly from its source ex: nitrogen dioxide,

Back

air pollution

Front

harmful concentrations of gases or aerosols in the atmosphere ex:dust, fossil fuels ,smoke

Back

Air Quality Index (AQI)

Front

useful tool to determine levels of air pollution at a given location

Back

acid rain

Front

forms when sulfur dioxide combines with nitrogen compounds to form sulfuric acid, which gets incorporated into water droplets

Back
