  15. Which of the following is an important contributor to both global warming and ozone depletion? An increase in the concentration of carbon dioxide to higher-than-preindustrial levels A buildup of methane in the stratosphere to higher-than-preindustrial levels An increase in the levels of ultraviolet radiation reaching Earth’s surface An increase in the amount of infrared solar radiation absorbed in the troposphere A release of chlorofluorocarbons to the atmosphere

  17. Smoke from forest fires is most likely to affect air quality over larger areas for many days when Smog is produced due to chemical reactions in the atmosphere A persistent atmospheric inversion exists in the region Oak trees are burned, releasing terpenes into the atmosphere Primary, rather than secondary, forests are burned Vegetation in the region is green and burns more slowly

  19. Which of the following best explains why it is predicted that ozone depletion over the poles will be at its worst between 2010 and 2019? Projected global warming from carbon dioxide emissions is expected to reach a peak during those years. Ozone-depleting chemicals produced before their use was banned will take that long to reach peak concentrations in the stratosphere. Deforestation in tropical regions is expected to reach a peak during the second decade of the twenty-first century. Increased global population will lead to an increase in per capita carbon dioxide production. Acid deposition will continue to increase, reaching a peak in approximately 2015.

  35. AP Environmental Science Atmosphere Notes Time to write

  36. Add the following layers to your atmospheric diagram • Troposphere: 0-11 km • Tropopause: 11 km • Stratosphere: 11-50 km • Main concentration of ozone layer: 15-40 km • Stratopause: 50 km • Mesosphere: 50-80 km • Mesopause: 80 km • Thermosphere: 80-500 km • You may want to color the layers. Keep your diagram neat; we’re going to use in when we take notes on atmospheric chemistry later.

  37. Temperature Ranges • Troposphere: -55 to 20°C • Tropopause: -55°C • Stratosphere: -55 to 0°C • Stratopause: 0°C • Mesosphere: -85 to 0°C • Mesopause: -85°C • Thermosphere: -85 to 2000°C

  38. Pressure is high in troposphere; as altitude increases, pressure decreases steadily. Add a line for this to your diagram. • Draw tiny buildings, people, cars, mountains, trees, planes, etc. in the troposphere. Also draw clouds in this layer (the troposphere is the layer in which weather “happens”). The troposphere also contains harmful ozone--O3, “bad ozone”. • The stratosphere contains a protective ozone layer—O3, “good ozone”. • Note that “bad ozone” and “good ozone” are chemically identical. The reason that one is good and one is bad is that ozone has harmful health effects on living things. At the same time, ozone absorbs some of the sun’s incoming ultraviolet radiation, which is good because UV also has harmful health effects on living things. So ozone is “good up high, bad nearby”.

  39. “Shooting stars” start to burn up in the mesosphere. Draw a few shooting stars in this layer. • Noctilucent clouds are also found in the mesosphere, far above the layer that normally contains clouds (the troposphere). Draw a noctiluence cloud in the mesosphere and label it. • Satellites orbit earth in the thermosphere. Draw a satellite or two here. Aurora borealis and aurora australis (the Northern and Southern Lights) also take place in the thermosphere, so draw them here (multicolored lights).
