Continental Hot Spots – Yellowstone Hot-Spot Trail. Use the Path tab on the Ruler tool to measure the distance between the Problem 21 placemarks (cm) along the hot-spot trail. Calculate the average velocity of the North American Plate in cm per year, using 16.5 Ma and 0.63 Ma for the two placemarks. a) ~1.9 cm per year
b) ~4.2 cm per year
c) ~8.8 cm per year
d) ~15 cm per year

4. now look at the green lines you created by connecting the three boiling point data points and the three melting point data points. for each of these lines, describe any trends you see. 5. locate the elements on your periodic table that you circled in green on your graph. what term or description would you use to identify these elements with respect to the periodic table? 7. using the room temperature line (orange line) and your periodic table, make lists that identify the state of matter (gas, liquid, or solid) in which each element you plotted exists at room temperature. explain your answers.
