  7. Plate Tectonics: The Revolution of the Earth Sciences

  8. Seafloor spreading forms ocean crust Studying the Ocean Floor

  9. Subduction Destroys Crust

  10. How Old is Ocean Floor ?

  11. Question: What direction is the Pacific Plate moving at the blue X ? X

  12. More Than 50,000 Seamounts

  13. How Does a Seamount Grow?

  14. Hotspots Make Seamount Chains

  15. = Present-day location of some select active hotspots How Many Active Hotspots?

  16. Western Pacific Hotspot Trails Press *6 to respond

  17. How Fast does the Pacific Plate Move? 1841 km 26.6 13.0 7.2 5.1 0 Age of seamount in million of years

  18. Poll Question: How fast does the Pacific Plate move?

  19. How Fast does the Pacific Plate Move? Distance from Active Hotspot = 1841 km Age of a Hawaiian Seamount = 26.6 m.y. Rate of Pacific Plate at Hawaii = 1841 km / 26.6 m.y. = 69 km/m.y. So, the rate of the Pacific Plate at Hawaii is 6.9 cm/yr
