Do not overlook the textbook and any outside readings (if applicable). Climate Change (1.) Explain the natural greenhouse effect, why it is important, where it occurs, and the molecules that contribute to the majority of the heat trapping. a. The Natural greenhouse effect elevates the temperature at the earth’s surface and allows liquid water to persist. (2.) Explain why incoming solar radiation is not absorbed as it passes through the earth's atmosphere, but heat from the earth is absorbed as it attempts to leave the earth's atmosphere and return to space. a. Since it has shorter wavelength so there is less energy to pass through (3.)

Unformatted text preview: temperatures at the earth's surface. a. Coal b. Oil c. Natural Gas i. Adds CO 2 into the atmosphere. It traps more heat and temps increase (4.) Describe the major sources of carbon dioxide emissions, and the relative emissions of the U.S. on a global scale. a. The majority comes from the burning of fossil fuels since it releases CO2 into the atmosphere. (5.) List and describe the three different types of greenhouse gases, and explain how these compounds contribute to global warming. a. Chlorofluorocarbons b. Methane (natural gas) c. Nitrous Oxide (N 2 0) (6.) Explain the fate of the Kyoto protocol since 2000, and the public’s opinions on the topic of global warming. a. The resolution passed unanimously, but why is the US hesitant? (7.) Explain how global warming may affect sea levels, crop yields, the climate in Northern Europe, and the global “conveyor belt” of sea currents that carry equatorial heat to higher latitudes....
