- 1What is the contamination of the atmosphere by the introduction of pollutants from human and natural sources?Air pollution
- 2Examples of primary air pollutantsCarbon monoxide, smoke, and chemicals from paint
- 3How are secondary pollutants formed?When natural occuring substances or primary pollutants react with other primary pollutants
- 4What are two examples of secondary pollutants?Ozone and smog
- 5One reason why the ozone near the Earth's surface is dangerous?Ozone= pollutant that negatively affects the health of organisms
- 6How is smog formed?when ozone and vehicle exhaust react with sunlight
- 7How much human-caused air pollution in the U.S. is caused by cars?10-20%
- 8List two sources of industrial air pollutionauto body shops, furniture refinishers
- 9Two ways to reduce indoor air pollution?ventilation and limiting the use of chemical solvents and cleaners
- 10Acid precipitation contains rain, sleet, or snow w/ a high concentration of acids that come from....nitric acid
- 11What are three of the forest areas in the world that are affected by acid precipation located?eastern europe, northeastern U.S., eastern canada
- 12Rapid change in the acidity of a body of water?Acid shock
- 13Main problem caused by the ozone hole?Uv radiation reaches the earth's surface which can cause skin cancer and damages genes
- 14Three effects of air pollution on human health?headaches, nausea, lung cancer
- 15Two ways industries reduce air pollution?By using scrubbers + focusing on burning fuel more effeciently
- 16Two ways car manufactures are trying to reduce air pollution?building more efficient engines, and making cars that run on electricity
- 17Two ways people can reduce air pollution from vehicles?Carpooling or biking to your destination
- 18What is wind?movement of air caused by differences in air pressure
- 19Warm, less dense air creates areas of low....air pressure
- 20Convection cells-air that travels in circular patterns
- 21Pressure belts-seperate convection cells at every 30 degrees
- 22Coriolis effect-the constant curved moving of the currents + winds in a circular motion
- 23Polar easterlies-wind belts found between 30 + 60 degrees latitude
- 24Westerlies-wind belts found between 30+60 degrees latitude
- 25Trade winds-winds that blow from 30 degrees latitude to almost the equator
- 26The doldrums-trade winds of the northern and southern hemispheres that meet in an area around the equator
- 27Horse latitudes-at 30N and 30S latitude, sinking air the creates an area of high latitudes
- 28Jet streams-narrow belts of high speed winds that blow in the upper troposphere and lower statosphere
- 29Local winds-winds that are affected by geological features
