1 ESC3704 Name 56 points October 27, 2010 19 students took exam - Numbers to the left of the question number in red are the number of incorrect responses. Instructor comments are in blue . Florida Atlantic University Environmental Issues in Atmospheric and Earth Science Second Midterm Examination Key True-False - Print the letter T or F in the blank to indicate if each of the following statements is true or false. Illegible answers are wrong. (1 point each) 0 T 1. Warmed structures and plants inside the greenhouse re-radiate absorbed visible light energy in the infra-red, to which glass is partly opaque, and that energy is trapped inside the glasshouse, which keeps the greenhouse well above the temperature of the surroundings. 6 T 2. As a blackbody radiator is heated, the wavelength of the radiation it emits decreases, and the intensity increases. 8 F 3. If there were no natural greenhouse effect, earth would be a three to five degrees Celsius cooler than it is. It would be about 33° cooler. 3 F 4. The major gases in the earth’s atmosphere, nitrogen and oxygen, are important greenhouse gases. 7 F 5. At the present time, deforestation of temperate zone forests is the largest contributor of carbon dioxide from deforestation. 1 T 6. Burning coal releases sulfur dioxide, which forms atmospheric hazes. These hazes help to cool the climate. 3 T 7. Permafrost melting in the arctic releases methane as the permafrost melts. This creates a positive feedback. 1 T 8. Methane levels in the earth’s atmosphere have more than doubled since the start of the industrial revolution in 1850. 4 F 9. Newer fluorocarbons, such as hydrofluorocarbons (HFC’s), do not contribute to the greenhouse warming of earth.

2 1 F 10. In December, 1997 a conference of governments in Kyoto, Japan drafted a document now known as the Kyoto Protocol to the International Framework Convention on Climate Change. The United States is a signatory nation to both the Framework Convention and the Kyoto Protocol. 2 F 11. Water is a very compressible fluid. 1 T 12. Exponential change may either be positive, like population growth, or negative, like radioactive decay. 5 F 13. Atmospheric pressure increases exponentially as altitude increases. 2 F 14. As relative humidity increases, it becomes easier to evaporate water. 1 T 15. As greenhouse gas concentration increases, so does the skin altitude. Increasing skin altitude produces greenhouse warming. 4 T 16. If the atmosphere were incompressible, there would be no greenhouse warming effect. 2 F 17. Negative feedbacks destabilize a system by amplifying changes to the system. 0 T 18. Meltwater lakes are now seen at higher altitudes in Greenland than they were a decade ago. 0 T
