2 Name: 8. Deep currents are caused mostly by a. surface winds. b. differences in density. c. the Coriolis effect. d. upwelling. 9. Which of the following types of current typically carries cold, dense water from the poles toward the equator? a. surface currents b. longshore currents c. deep currents d. rip currents 10. The movement of cold, deep ocean water to replace warm water at the surface is called a. upwelling. b. a surface current. c. the Coriolis effect. d. El Niño. 11. Climates are classified according to two major factors: a. elevation and precipitation. b. latitude and temperature. c. elevation and latitude. d. precipitation and temperature. Essay 12. Explain why one hemisphere has spring at the same time the other hemisphere has autumn. 2

3 Name: 13. Define upwelling and explain its importance. 14. Briefly describe two hypotheses for the cause of global warming. 15. Explain how carbon dioxide, according to the Greenhouse Hypothesis, causes an increase in global warming. 3

4 Name: 16. Explain how clouds might effect global temperatures, according to the Greenhouse Hypothesis. Include in your answer positive and negative feedbacks as it relates to heating and cooling. 17. Explain how clouds might effect temperatures according to the Climate Variation Hypothesis. Include in your answer negative and positive feedbacks as it relates to changes in temperatures. 18. Explain what Climate-Sensitivity is. 4

5 Name: 19. Explain the causes of global climate change according to the Climate Variation Hypothesis. 5

6 Name: 20. Write a paper explaining everything you know about Climate Change. Include in your responce, your view of Global Climate Change, the reasons for your view, how you think climate change will or won t effect people in the futare, if you think the government is doing good with their choices towards climate change and how so, if you think there are other or better ways the government should be spending money and time on this issue and how so. Also be sure to include information about climate sensitivity, forcing, and feedbacks in your discussion. Finally, do you think the media, politicians, etc. should be able to exaggerate Global Warming? Why or why not? (10 points) 6

9 Ch. 9 Climate Test Answer Section MULTIPLE CHOICE 1. A 2. C 3. D 4. A 5. C 6. A 7. A 8. B 9. C 10. A 11. D ESSAY 12. The seasons are caused by the tilt of Earth s axis as Earth revolves around the sun. In March and September, neither end of Earth s axis is tilted toward the sun. The Northern and Southern Hemispheres both receive about the same amount of sunlight. 13. Upwelling is the upward movement of cold water from the deep ocean to replace warm surface waters blown away by winds. Upwelling keeps surface waters supplied with nutrients by moving small organisms, minerals, and nutrients up from deep waters. Upwelling areas are frequently home to large schools of fish. 14. Some scientists think global warming results from an increase of greenhouse gases in the atmosphere due to people s burning of fuels. Others think global warming is caused by natural changes in solar energy, or by a combination of this and increased greenhouse gases. 15. sdsdcf 16. dsfgdsfg 17. dsfsdfg 18. sdfsadf 19. dsdssadfg 20. sdfgh 1
