BIO 130 EXAM (ARIZONA STATE UNIVERSITY)

1. Globally speaking, some countries (like France and Belgium) use nuclear power to supply more than half of their energy needs.
2. What are the 2 major concerns about nuclear energy?
3. How much radiation is the average U.S. citizen exposed to in a single year?
4. What type of cancer was elevated among children who drank milk that contained radioactive iodine from the area around Chernobyl after the nuclear disaster there?
5. What is the half-life of ²³⁹Pu (the radioactive waste from nuclear power plants)? Remember, the half-life is how long it takes for half of the radioactive materials to decay.
6. Because nuclear energy requires so few mineral inputs to create a lot of energy, it is considered to be a renewable form of energy.
7. High doses of radioactivity can cause death in days to months after exposure.
8. After many years of debate, the U.S. now has a permanent disposal facility that is accepting and storing nuclear waste in an underground geologic repository in Nevada.

10. Which of the following is NOT a primary concern of nuclear power?
11. Fish ladders are ___________________.
12. Which of the following is a disadvantage of ethanol (a biofuel) for fuel?
13. Solar power accounts for a larger share of electricity (and overall energy) production in the U.S. than hydropower.
14. Solar water heaters work by circulating water through tubes in a black material that absorbs heat from solar radiation.
15. Firewood is still a primary source for heat and cooking for many people across the world.
16. Which of the following is NOT a form of renewable energy?
17. How has the use of wind power changed (or not) in recent years within the U.S.?
18. What are the 2 main ways that we use geothermal energy?
19. The source of energy for tidal power is the gravitational pull of the Moon
20. Death to birds by spinning turbines is a disadvantage to which renewable energy source?
21. Scientists have extracted long cores from the Antarctic ice sheets. How far "back in time" do these cores go? In other words, they can tell us the climate on Earth only up to about ______ years ago.
22. What are some implications of global climate change on human health? Select all that apply.
23. Polar bears are literally drowning due to low levels of Arctic summer sea ice, as they depend on this ice to rest when they are out hunting.
24. One of the most recent reports of the IPCC (Intergovernmental Panel on Climate Change) stated that the global warming of air and water systems is "unequivocal."
25. Which decade in the past was the hottest (overall) on record, globally?
26. Climate oscillations, which include ice ages and warm periods, have a documented pattern called ____________ Cycles.
27. Who was the non-scientist whose observations led to a new field of science called paleoclimatology?
28. The IPCC (Intergovernmental Panel on Climate Change) was composed of 50 scientists, one from each state within the U.S.
29. The extent of Arctic sea ice has started to shrink, while sea level has already started to rise around the world, as a result of global warming.
30. How is global climate change influencing precipitation events?
31. Fossil fuels store energy that was captured from the Sun millions of years ago.
32. From the movie "The True Cost of Oil" with Garth Lenz, he refers to tar sands oil as _____________.
33. The burning of fossil fuels has been tied to global warming
34. If we could cut our consumption of fossil fuels in half, they would be a renewable source of energy.
35. Which of the following is NOT true about tar sands mining?
36. In the mountain regions of West Virginia, Kentucky, Tennessee and Virginia, more than 470 mountains have been "affected" by surface coal mining (which means they were dug up and deposited in stream valleys in order to get to coal).
37. Natural gas use is on the rise, partially due to fracking technologies which have made it easier to access natural gas supplies (and has driven the cost down).
38. Which of the following is NOT an option for reducing the environmental impact of fossil fuels for energy?
39. Petroleum and natural gas formed from the same ancient decaying critters, but natural gas formed lower underground such that it was subjected to higher pressures and temperatures.
40. "Production" of oil/petroleum refers to _____________.
41. Energy consumption per household, has not changed by more than 1 or 2% since 1980.
42. Which of the following is/are a form(s) of kinetic energy? Select all that apply.
43. What is the primary energy source used to generate electricity?
