21. Describe hydrofracking, what energy sources are obtained through hydrofracking?
22. Describe two types of coal mining. What environmental impacts occur the mining and use of coal?
23. List six (6) sources of alternative energy. Which are renewable and non-renewable?
24. How do dams provide energy? How do wind turbines provide energy?
25. How photovoltaic cells provide energy?
26. What are the cheapest sources of electrical energy?
27. What country produces the most petroleum currently in the world?
28. What country uses the most petroleum in the world? (extra credit - Why?)
Long answer I will pick four (4) to five (5) of the following questions:
1. Discuss population change worldwide, and factors that have resulted in the slowing rate of population growth. I expect a detailed answer here, with examples.
2. Describe why the Malthusian theory helps understand population growth, and then describe why it is incorrect in describing the situation of population growth currently.
3. How does photosynthesis represent the concept of stored solar energy?
4. How do the ideas of renewable and nonrenewable energy sources relate to the concept of sustainability?5. Describe the different between a food chain and a food web. Then describe how one is a better description of an ecological system.
6. Describe the carbon cycle and break it down between the long and short portions of the cycle. Give examples in the cycles.
7. Be able to label a diagram on the hydrologic cycle.
8. Describe why replacing and adding new powerlines is so important. This should be a detailed and should note why this is important to wind and solar power.
9. What are some of our cheapest sources of electricity? What does the indicate about what energy sources we might be using in the future primarily?
10. What are the long-term implications of not replacing fossil fuels with alternate energy sources? Define what a fossil fuel is in your answer.
11. Why is the storage of electrical energy so important to development of alternative energy? Give two (2) examples for storing electrical energy?
12. Describe the how photovoltaic cells work and compare that to how wind turbine works. Contrast the two systems and indicate what they have in common and not have in common.
13. Describe how a dam works, and why it's such a reliable source of energy. Then provide a description of how a dam can cause serious environmental problems on rivers when they are installed, and how that problem can be fixed?
14. Describe the method for collecting energy from the world's ocean currents. Where is this being used currently, and what concerns could this raise?
