The map in Fig. A2.3.1 shows the distribution of a trail of volcanic centers in Wyoming. Idaho, and Nevada. All of these volcanic centers are now inactive except the youngest one located in Yellowstone National Park. Hot springs, geysers, and earthquakes demonstrate that Yellowstone is still volcanically active. 1. What does this progressive chain of volcanic centers indicate about the possible origin of the active volcanism at Yellowstone? Support your answer with evidence 2. Based on the map, what was the average speed and direction of North American Plate motion at Yellowstone, relative to the hotspot, since 13.8 Myr? Add an arrow (vector) and rate label to the map in Fig. A23.1 to show this movement. 3. Plate Boundary Observatory GPS station P717 near the east gate of Yellowstone National Park had the following component velocities relative to the NNR reference frame as of January 24. 2016: moving south at 0820000088 cm/yr and moving west at 1.478300068 cm/year (a) Use the Pythagorean Theorem to find the current speed of the North American Plate at P717 relative to the NNR reference frame. Show your work. ellowstone National Par Yellowstone National Park 10.3 125 13.8 Figure A2.3.1 (b) How do the present-day direction and speed of P717 relative to the NNR reference frame compare with your estimate of the average direction and speed of the North American Plate relative to the hotspot during the past 13.8 Myr?
