Locations of hot spots remain fixed for a long time. As
plates move across such hot spots, they form chains of volcanoes. The
Hawaiian Islands are an example of such an island chain formed over a
hot spot. Volcanoes on the Island of Hawaii are still active. Moving
northwest, the volcanoes are extinct. The age of the extinct volcano,
located 4,000 km away from the Hawaiian Islands, is 40 million years old.
What is the rate of movement of the Pacific Plate?
Would I divide 4000km/40million? would that give me the rate of movement?
