1. Hot Spots

3. A major hot spot in the Pacific ocean created the Hawaiian Island and Emperor Seamount island chains.

7. Radiometric Dating shows that the Hawaiian island volcanic structures increase in age with increasing distance from Hawaii.

9. Hot Spot – area of volcanism, high heat flow, and crustal uplifting that is a few hundred km across.

10. As the Pacific Plate moved over this hot spot, successive volcanic structures were built.

11. The age of each volcanoe indicated the time it was situated over the Mantle Plume (Hot Spot).

12. The Hawaiian Island – Emperor Seamount chain (linear volcanic structures) are sometimes referred to as Hot Spot Tracks.

14. Hot spots may remain active for over 100 million years.

15. The mantle plume (Hot Spot) DOES NOT MOVE. Therefore, hot spots track the Direction of Plate Motion.

16. At least 40 hot spots exist, some occur on or near the ocean ridge system, such as Iceland.

17. Other are located in The Interior of a Plate, such as the one beneath Yellowstone National Park.
