You will answer two of the following "Test Your Comprehension" Questions on page 553 & 554:
1. What happens to solar radiation after it reaches Earth? How do greenhouse gases warm the lower atmosphere? (6 points) 3. How do scientists study the ancient atmosphere? (4 points) 7. What are some likely negative impacts of warmer climate on human health? Could there be beneficial consequences? (7 points) 9. What are the largest two sources of greenhouse gas emissions in the US, and why? In what ways can we try to reduce these emissions? (6 points) You will answer two of the following four questions from "Testing Your Comprehension" on page 617
2. Describe how nuclear fission works. How do nuclear plant engineers control fission and prevent a runaway chain reaction? (5 points) 6. List 5 sources of biomass energy. What is the world's most-used sources of biomass energy? How does biomass energy use differ between developed and developing nations? (8 points) 7. Describe 2 biofuels, where each comes from, and how each is used (6 points) 10. Assess two benefits and two negative environmental impacts of hydroelectric power (4 points) Here are the questions (also found on page 429 - 430)
4. When did concern over the effects of pesticides start to grow in the United States? Describe the argument presented by Rachel Carson in Silent Spring. What policy resulted from the book's publication? Is DDT still in use? 5. List and describe the six types of general categories of toxicants described in the chapter. 6. How do toxicants travel through the environment? Describe the process of bioaccumulation and biomagnification. Completing these two chapters will take us to the end of the semester. Here are some important dates:
Click HERE for the chapter 15 ppt's Here are the three potential quiz questions. You will answer one. Have responses for them read by Thursday so that we can discuss & debate during class! They are taken from the "Seeking Solutions" section found on page 526 of Withgott. 2. How may human activity sometimes exacerbate (make worse) natural forms of air pollution? Discuss two examples and potential solutions. 3. Describe how and why emissions of major pollutants have been reduced by over 50% in the US since 1970, despite increases in population and economic activity. 5. Consider volatile chemicals, such as formaldehyde and other VOC's that may be emitted at very low levels over long periods of time from manufactured products. What do you think are the best ways to lessen the health impacts of such indoor pollutants? Click HERE for a link to the EPA's webpage about the Clean Air Act (CAA) Here's an excellent short documentary that shows how air and water pollution are closely linked. Remember to spend no more than 22 minutes working on it. We will score it together during class. If you get this message, please forward it on to others who may not be following me on twitter! It's questions #4 about biodiversity.
Thanks! This short cartoon connects nicely with the winogradsky columns we (finally) completed today. It will be interesting to see how these change over time.
Here are the possible question for your next quiz. These are on page 179 of your textbook. You will need to answer two of the five listed below.
1. How does competition lead to a realized niche? How does it promote resource partitioning? 2. Contrast the several types of exploitation. How do predation, parasitism, and herbivory differ? 4. Explain how trophic levels, food chains, and food webs are related 5. Explain and contrast primary and secondary terrestrial succession. 8. What factors most strongly influence the type of biome that forms in a particular place on land? What factors determine the type of aquatic system that may form in a given location? Notes on chapter 5: Evolution, Biodiversity, and Population Ecology For the quiz, you will be asked to answer three of the following six "test your comprehension" questions: 1. Express the premises and logic that supports the concept of natural selection. 3. Name two examples of evidence for natural selection. 6. Contrast the concepts of habitat and niche. 8. Could any species undergo exponential growth forever? Explain your answer. 9. Describe how limiting factors relate to carrying capacity. 10. Explain the difference between K-selected species and r-selected species. Can you think of examples of each that were not mentioned in the chapter? everything you need to know about Evolution (and more!) |
