APES Chapter 19 Air Pollution Questions With Complete Solutions

Primary air pollution correct answer: A harmful substance such as soot of carbon monoxide that is emitted directly into the atmosphere Secondary air pollution correct answer: A harmful substance formed in the atmosphere when a primary air pollutant reacts with substances in the atmosphere or with other air pollutants Particulate matter correct answer: Matter that consists of thousand of different soldi and liquid particles suspended in the atmosphere and includes dusts and mists. It includes solid particles soot lead abestos, sea salt, and sulfuric acid, reduces visibility and is harmful to health Ozone correct answer: A pale blue gas that is an essential component that screens out UV radiation in the upper atmosphere (stratosphere) and but is a pollutant in the lower atmosphere (troposphere) Troposphere, stratosphere, mesosphere, thermosphere (TSMT) correct answer: What are the layers of the atmosphere on order Photochemical smog correct answer: A brownish orange haze formed by chemical reactions involving sunlight, nitrogen oxide, and hydrocarbons Volatile Organic Compounds correct answer: Carbon based chemical that evaporates easily at room temperature, contributes to smog production Temperature inversion correct answer: A deviation from the normal temperature distribution in the atmosphere resulting in a layer of cold air temporarily temporarily trapped near the ground by the warmer upper layer Clean Air Act correct answer: Set modern standard for air quality regulation, authorizes the EPA to set limits on the amount of specific air pollutants permitted everywhere in the US: amendments focused on controlling motor emissions by development of super clean cars, industrial air born emissions drug cleaners and such has to install pollution controlling equipment Ultraviolet radiation correct answer: That part of the electromagnetic spectrum with wavelengths just shorter than visible light Stratospheric ozone thinning correct answer: That accelerated destruction of ozone in the stratosphere by human produced chlorine and bromine containing chemicals Chlorofluorocarbons (CFCs) correct answer: Human made organic compounds of carbon , fluorine, and chlorine that had many industrial and commercial applications but were banned because of their attack omg the stratospheric ozone layer Montreal Protocol correct answer: (1987) an agreement made that originally stipulated a 50% reduction of CFC production by 1998: international negotiations that resulted in a timetable to phase out CFCs production Acid deposition correct answer: Sulfur dioxide and nitric oxide emissions that react with water vapor in the atmosphere to form acids that return to teh surface as either dry or wet deposition Forest decline correct answer: A gradual deterioration (And often death) in a forest that may be the
