13. Using Google Earth, locate the Yellowstone Caldera in northwest Wyoming (search for \( 444360 \mathrm{~N} \), \( 1104160 \mathrm{~W} \)-you can mark this spot with a placemark using the yellow pushpin along the top bar). Now search for the McDermitt volcanic field by searching for \( 41511 \mathrm{~N}, 118212 \mathrm{~W} \). Also put a placemark here. Using the measure tool, determine the distance between these 2 locations in centimeters. What is this distance? 14. Using the age of \( 16.5 \mathrm{Ma} \) for the MeDermitt volcanic field and \( 0 \mathrm{Ma} \) for the Yellowstone Caldera, calculate the speed at which the North American plate is moving over the Yellowstone hot spot. a. \( 4 \mathrm{~cm} / \mathrm{yr} \) b. \( 0.2 \mathrm{~cm} / \mathrm{yr} \) c. \( 2 \mathrm{~cm} / \mathrm{yr} \) d. \( 41 \mathrm{~cm} / \mathrm{yr} \) 15. Where was the McDermitt volcanic field located when it was still active and erupting? a. \( 41511 \mathrm{~N} 118212 \mathrm{~W} \) b. \( 423148 \mathrm{~N} 1062543 \mathrm{~W} \) c. \( 514549 \mathrm{~N} 1171008 \mathrm{~W} \) d. \( 444360 \mathrm{~N} 1104160 \mathrm{~W} \) 16. Calculate the density of each of the 4 rocks in Figure 5 . The rock that most closely resembles the composition of continental plates based on the description in the previous section is: a. A b. B c. C d. D 17. Based on the choice you made for question 16 , what is the density of the rocks that make up continental plates? a. \( 2.11 \mathrm{~g} / \mathrm{cm}^{3} \) b. \( 2.75 \mathrm{~g} / \mathrm{cm}^{3} \) c. \( 2.99 \mathrm{~g} / \mathrm{cm}^{3} \) d. \( 0.5 \mathrm{~g} / \mathrm{cm}^{3} \) 18. The rock that most closely resembles the composition of oceanic plates based on the description in the previous section is: a. A b. B c. C d. D 19. Based on the choice you made for question 18 , what is the density of the rocks that make up oceanic plates? a. \( 2.11 \mathrm{~g} / \mathrm{cm}^{3} \) b. \( 2.75 \mathrm{~g} / \mathrm{cm}^{3} \) c. \( 2.99 \mathrm{~g} / \mathrm{cm}^{3} \) d. \( 0.5 \mathrm{~g} / \mathrm{cm}^{3} \) 20. According to the geothermal gradient, rocks buried \( 60 \mathrm{~km} \) beneath the surface would normally be at what temperature? 20. According to the geothermal gradient, rocks buried \( 60 \mathrm{~km} \) beneath the surface would normally be at what temperature? At \( 60 \mathrm{~km} \) depth, rocks will be heated to about degrees Celsius 21. According to the geothermal gradient, rocks at 750 degrees Celsius will be buried how deep? At 750 degrees Celsius, rocks will be buried to about \( \mathrm{km} \) depth a. 8 b. \( 12.5 \) c. 20 d. 25 22. What happens when the lithosphere at point \( \mathrm{X} \) is heated to \( 1750^{\circ} \mathrm{C} \) ? a. starts to melt b. starts to crystallize c. no change 23. At which of the following depths will the dry mantle rock at point \( \mathrm{X} \) begin to melt if its temperature remains the same? a. \( 45 \mathrm{~km} \) b. \( 55 \mathrm{~km} \) c. \( 75 \mathrm{~km} \) d. \( 10 \mathrm{~km} \) 24. Type " \( 195710.35 \) S \( 752346.24 \) W" into the Google Earth Pro Search bar and zoom out to \( \sim 1,000 \) miles. What type of tectonic plates are present? a. Ocean-Continent b. Ocean-Ocean c. Continent-Continent. 25. What type of plate tectonic boundary is present? a. Transform b. Convergent c. Divergent Yellowstone hotspot track, and can be seen in Figure \( 3 . \) Figure 3.
