  1. AP Review Questions Air Pollution

  2. What layers are found in the atmosphere?

  3. What are the major outdoor air pollutants, and where do they come from?

  4. What are two types of smog?

  5. What is acid deposition, and how can it be reduced?

  6. What are the harmful effects of air pollutants?

  7. How can we prevent and control air pollution?

  8. How have the earth’s temperature and climate changed in the past?

  9. How might the earth’s temperature change in the future?

  10. What factors influence the earth’s average temperature?

  11. What are some possible beneficial and harmful effects of a warmer earth?

  12. How can we slow projected increases in the earth’s temperature or adapt to such changes?

  13. How have human activities depleted ozone in the stratosphere, and why should we care?

  14. Global air circulation is affected by • uneven heating of the earth’s surface by solar energy, seasonal changes in temperature and precipitation

  15. Wind is caused by • the pressure gradient force. • High pressure means more air, and low pressure means less air. The air moves from high to low, causing wind.

  16. Global air circulation is affected by rotation of the earth on its axis.

  17. Forces in the atmosphere, created by the rotation of the Earth on its axis, that deflect winds to the right in the N. Hemisphere and to the left in the S.Hemisphere is known as • The Coriolis Effect

  18. Heat and moisture are distributed over the earth’s surface by vertical currents form six giant convection cells at different latitudes called • Hadley Cells

  19. What are cyclones called in various parts of the Earth? • called hurricanes in the Atlantic and typhoons in the Pacific

  20. Why are deserts found at 300 latitude? • Wind rises at the equator. • As air rises, it spreads out north & south, then cools and sinks at 30 degrees.

  21. Ocean water transfers heat to the atmosphere, especially near the hot equator which creates • convection cells

  22. The resulting convection cells circulate • air, heat, and moisture both vertically and from place-to-place in the troposphere, leading to different climates & patterns of vegetation

  23. What are ocean-to-land breezes that occur during the day? • Sea Breeze

  24. What are land-to-ocean breezes that occur at night? • Land Breeze

  25. Prevailing winds that blow from the northeast near the North Pole or from the southeast near the South Pole are called • polar easterlies.

  26. Tropical winds that blow from the northeast in the N. Hemisphere or from the southeast in the S. Hemisphere are called • trade winds.

  27. Continental fronts are generally cool and dry, whereas maritime (ocean) fronts are generally warm and moist. When these two air masses converge, the result is usually • rain.

  28. What is the boundary between an advancing warm air mass and the cooler one it is replacing? • Warm Front

  29. What is the leading edge of an advancing air mass of cold air called? • Cool Front

  30. A cold front produces rapidly moving, towering clouds called • thunderheads.

  31. What is the air front established when a cold front prevents the passage of a warm front. • Occluded Front

  32. Ocean currents influence climate by • distributing heat from place to place and mixing and distributing nutrients.

  33. The atmosphere’s innermost layer is made up mostly of nitrogen and oxygen, with smaller amounts of water vapor and CO2is called • troposphere

  34. What is the atmosphere’s second layer called? • Stratosphere

  35. What filters out most of the sun’s UV radiation that is harmful to us and most other species? • ozone

  36. In what atmospheric layer is ozone found? • stratosphere

  37. Describe the troposphere. • 75% of mass of atmosphere • 0 to 11 miles in altitude • 78% nitrogen, 21% oxygen • Location of Earth’s weather • Temperature decreases with altitude until the next layer is reached, where there is a sudden rise in temperature

  38. Describe the stratosphere. • 11 miles to 30 miles in altitude • Calm • Temperature increases with altitude • Contains 1000x the ozone of the rest of the atmosphere; ozone forms in an equilibrium reaction when oxygen is converted to O3 by lightning and/or sunlight • 99% of ultraviolet radiation (especially UV-B) is absorbed by the stratosphere

  39. Describe the mesosphere. • 30 to 50 miles in altitude • The temperature decreases with increasing altitude

  40. Describe the thermosphere. • 50 to 75 miles in altitude • Temperature increases with increasing altitude • Very high temperatures

  41. What causes the seasons? • The Earth’s 23.5 degree incline on its axis remains the same as it travels around the sun. • As the earth revolves around the sun the seasons change.

  42. the condition in the atmosphere at a given place and time which includes temperature, atmospheric pressure, precipitation, cloudiness, humidity, and wind is called • weather

  43. the average weather conditions that occur in a place over a period of years is called • climate

  44. What are the two most important factors in climate • Temperature and precipitation

  45. What are causes of Primary Pollutants? • factories, cars, wind and soil, volcanoes, forest fires, pollen, decaying plants, salt particles from the sea, and refrigerants.

  46. Some primary Pollutants include: • methane, ozone, dust particles, microorganisms, and chlorofluorocarbons (CFC’s), CO, CO2, SO2, NO, NO2 , suspended particulates

  47. What is a highly toxic gas that forms during the incomplete combustion of carbon-containing materials. • Carbon monoxides (CO)

  48. What adds most CO2 into the atmosphere? • Human activities such as burning fossil fuels

  49. Is CO2 regulated as a pollutant under the U.S. Clean Air Act? • No

  50. What forms when nitrogen and oxygen gas in air react at the high-combustion temperatures in automobile engines and coal-burning plants? • Nitrogen oxide (NO)
