11. How Old is Ocean Floor ?

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

13. More Than 50,000 Seamounts

14. How Does a Seamount Grow?

15. Hotspots Make Seamount Chains

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

17. Western Pacific Hotspot Trails
Press *6 to respond

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

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

20. 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
