how the Hawaiian Islands were formed and how they are evidence for mantle plumes.
This observation is a strong evidence for the theory that volcanic hotspots like the Hawaiian Islands originate from mantle plumes generated at the Earth's core-mantle boundary.ew explanation for Hawaiian hot spot. (PhysOrg.com) -- Scientists in the US have suggested that volcanic activity in Hawaii could be fed by a giant hot rock pool 1,000 kilometers west of the islands and in the Earths mantle, rather than being fed by a hot ...
In areas where the plates come together, sometimes volcanoes will form. Volcanoes can also form in the middle of a plate, where magma rises upward until it erupts on the sea floor, at what is called a âhot spot.â. The Hawaiian Islands were formed by such a hot spot occurring in the middle of the Pacific Plate.While the hot spot itself is fixed, the plate is moving. So, as the plate moved over the hot spot, the string of islands that make up the Hawaiian Island chain were formed.The Hawaiian Islands form an archipelago that extends over a vast area of the North Pacific Ocean.olcanoes can also form in the middle of a plate, where magma rises upward until it erupts on the sea floor, at what is called a âhot spot.â.
