Name: ______Society Islands Hotspot The are located in the South Pacific Ocean, west of Australia. The reason I chose these islands for analysis is that they are in line with another famous island chain hotspot that we have already studied. What is the famous island chain hotspot we’ve already studied? ______What plate do both sets of islands hotspots sit on? ______1. Find the distance from Mehetia to . Fill the information in the first column of the data table. 2. Multiply your value by 50 and fill the information in the second column of the data table.  Complete the same procedure to determine the distance from Mehetia to each of the other volcanic locations. 3. Convert the kilometer distance to centimeters by multiplying by 100,000 and record the value. 4. Calculate the rate at which the Pacific Plate moved since the formation of Mehetia by dividing the distance by the age of each location. Fill the value in on your data table.  Complete the same procedure to determine the rate of movement since the formation of Mehetia. 5. After you have found the rates of movement since the formation of each Volcanic location, average the numbers (add them up and divide by seven) to find the average rate of the Pacific Plate. Location Distance Distance in km Distance in cm Age (years) Rate (Distance/Age) on map (x50) (x100,000 to get in cm centimeters)

Mehetia 0 Tahiti 1,000,000 Moorea 1,500,000 2,520,000 Raiatea 2,600,000 Tahaa 3,000,000 Borabora 3,600,000 4,500,000 Average rate (cm/yr)

6. How does this analysis compare to the Hawaian Island hotspot analysis? Are they similar or different? Why?

7. Are the Hawaian Islands hotspot and Society Islands hotspot parallel? 8. On the back, color the convergent subduction boundaries of the Pacifc plate blue. 9. On the back, color the divergent boundaries of the Pacific plate red. 10. On the back, color the transform boundaries of the Pacific plate yellow. 11. Using the data obtained from the Hawaian Island and Society island hotspots, draw arrows in the direction of plate movement over each hotspot.

12. Compare the direction of movement over the two hotspots to the location of the subducting side of the Pacific plate. Does the direction match the locations? Why or why not?

13. Along the eastern side of the pacific plate, sits a divergent boundary. Why would you find this type of plate boundary here when the western side is a subducting plate?
