Salt Lake Community College - Geography 1000 Quiz #1 – Fall 2014 A. J. Allred, Adjunct 1. Student Name __________________ Which of the following describes the diameter of the earth? a. b. c. d. e. C/π 8,000 times π 24,000 times π 24,800 divided by 7,900 C times π 2. The scientific method starts with a sure proof and then works toward eventually finding ‘hunches’ by using statistical experiments. Science avoids theories because they are not provable and are often unreliable. True ___ False _X__ 3. World-wide, the metric system is giving way to the more popular English system of weights and measures. A mile is about ½ kilometer plus a little more. A meter is about one yard. A gallon is about ½ liter. True ___ False _X__ 4. Which of the following ‘spheres’ appears in the most places on Earth, and plays a key role in nearly all natural phenomena? That ‘sphere’ also helps define the ‘goldilocks’ region of our solar system. a. b. c. d. e. hydro litho bio atmo cryo 5. Which of the following is a good example of a negative feedback loop? a. b. c. d. e. 6. Which of the following is true regarding the Earth’s 24 time zones? a. b. c. d. e. 7. Melting ice and snow that gives way to dark water. Animals and plants that propagate and spread until they consume all available resources and then die back. Both of the examples above illustrate a negative relationship – a negative feedback loop. Neither of the examples above has anything to do with positive or negative feedback relationships or correlations. Both of the examples above are examples of a positive correlation – a positive feedback loop. At the Equator each time zone spans about 1,037 miles. At the north and south poles, an hour-long time zone spans less than one inch. At the Equator the Earth’s surface is spinning or rotating at about 1,000 mph. Time zones often follow political boundaries instead of lines of meridian All of the above are true of time zones. Which of the following statements is/are true? a. The tallest mountain on Earth is the Hawaiian ‘Big Island” because it rises about 20,000 feet from the ocean floor and then 13,500 more feet into the atmosphere. b. The point of lithosphere or ‘rock’ furthest from the center of the Earth is a volcano near the Equator, because the Earth’s diameter is fattest at the Equator, which adds to the height of any mountain along the Equator. c. Mt. Everest is the highest point of lithosphere from sea level. d. e. The deepest ocean trench is further from sea level than the top of any mountain peak on dry land. All of the above are true. 8. High-altitude commercial aviation can cause the Earth’s atmosphere to change temperature. True _X__ False ___ 9. The Earth rotates to the east. The vertical axis of rotation is not perpendicular to the horizontal ‘plane of the ecliptic’ with the Sun. So, seasons change as different parts of the earth face more or less directly at the Sun. True _X__ False ___ 10. Which of the following statements is false? a. All of Mr. Allred’s tests are “open-book and open notes” b. During tests, no electronic devices can be used if they are capable of outside communication. c. It is very important to read the textbook regularly. d. All students start the semester with a perfect “A” grade and will be expected to keep it. e. All of the above statements are false. 11. Utah has hosted which of the following events? a. b. c. d. e. The largest landslide in recorded North American history. The most expensive landslide in U.S. history. An earthquake of Magnitude 6.3 All of the above. None of the above. 12. For preparing your ePortfolio, you can freely use any picture or other graphic provided by a U.S. government source. Regardless of your sources of information, always acknowledge where you got them and try hard to comply with copyright restrictions. True _X__ False ___ 13. In some places prone to severe earthquakes, some public safety planners may have decided to “write off” small children as presumed to die during a tsunami wave inundation. True _X__ False ___ 14. In dry regions like Utah, public safety officials and city planners encourage flood waters to go where children play. True _X__ False ___ 15. Which of the following is true of the Earth’s axial tilt? a. b. c. d. e. The declination angle changes only very slightly over extremely long periods of time. The declination angle is about 23.5 degrees less than perpendicular to the ‘plane of the ecliptic’ with the Sun During the June Solstice, sunlight can reach over the top of the North Pole and down to the Arctic Circle on the other side, allowing no night-time darkness for at least one full day everywhere above the Arctic Circle. During the June Solstice, there will be at least one day of no daylight for regions further south than the Antarctic Circle. All of the answers above are true.
