How do seamounts form
WebSeamounts — undersea mountains formed by volcanic activity — were once thought to be little more than hazards to submarine navigation. Today, scientists recognize these structures as biological hotspots that support … WebHeat from the Hawaiian hot spot partially melts mantle rock at depths starting about 200-400 km (125-250 mi) below Earth's surface. This melting produces magma that rises upward through the overlying Pacific Plate. As the plate moves west-northwest, each volcano moves with it from its place of origin above the hot spot.
