the pressure exerted by the atmosphere on all objects within it
Colorless, odorless poisonous gas produced as a by-product of incomplete combustion; can be dangerous if not properly ventilate
Clean Air Act of 1970 and 1990
control air quality by putting limits on air pollution and emission levels. Wanted to reduce the depletion of the ozone layer
the weather in some location averaged over some long period of time
forms when cold air moves under warm air which is less dense and pushes air up (produces thunderstorms heavy rain or snow
air near the Earth's surface picks up moisture and rises, once it cools, it forms clouds and precipitates. cool dry air descends and the process repeats
The apparent curving of the path of a moving object from an otherwise straight path due to the earth's rotation
Formed when an air mass cools over an ocean or a cold region on land. This dense system moves outward toward low pressure systems, creating a wind. Causes, clear blue skies, is dry etc.
Type of air pollution consisting mostly of a mixture of sulfur dioxide, suspended droplets of sulfuric acid formed from some of the sulfur dioxide, and a variety of suspended solid particles. Compare photochemical smog.
a soft heavy toxic malleable metallic element
area with lower atmospheric pressure than its surrounding areas; this makes air from surrounding areas to flow into the low, the end result of which is probably cloudiness and precipitation
foul smelling red gas, from exhaust and industry, contributes to smog and acid precipitation
layer of the stratosphere with a high concentration of ozone; absorbs most of the Sun's harmful ultraviolet radiation
A diverse mixture of fine particles, both solid and aerosol, that impact human health. Shortened term is "PM."
a brownish haze that is a mixture of ozone and other chemicals, formed when pollutants react with each other in the presence of sunlight
pollutants that are put directly into the air by human or natural activity
measure of the amount of moisture held in the air compared with the amount it can hold at a given temperature; can range from 0% to 100%
pollutants that are formed when primary pollutants interact with sunlight and other gases in the atmosphere
Desulfurization systems that are used in smokestacks to decrease the amount of sulfur released in the air by 90% or more.
the layer of the atmosphere that is above the troposphere and in which temperature increases as altitude increases
a colorless toxic gas (SO2) that occurs in the gases from volcanoes
a stable thermal structure in the atmosphere in which warm air overlies cool air. Over cities and industrial areas, inversions cause buildup of air pollution
the layer closest to Earth, where almost all weather occurs; the thinnest layer
Secondary, formed from N oxides and volatile hydrocarbons, photochemical smog, forest decline, reduces air visibility & health problems
volative organic compounds
Carbon containing chemicals used in and emitted by vehicle engines and a wide cariety of solvents and industrial processes as well as by many household chemicals and consumer items.
moving weather front along which a warm air mass slides over a cold air mass, producing stratiform clouds and precipitation
the meteorological conditions: temperature and wind and clouds and precipitation
