The Hawaiian islands form as the Pacific plate moves over a stationary . The oldest volcano (e.g., Kauai) is farthest northwest, the youngest (Hawaiʻi) is active at the southeast end, showing the plate moves northwest over the fixed mantle plume.
Formed when an oceanic plate subducts under a continental plate (e.g., the Andes Mountains or the Cascade Range). section 10.1 volcanoes and plate tectonics worksheet answers
Rocks melt when their temperature rises above their melting point. In the crust, heat can come from friction at subduction zones or rising mantle rock. The Hawaiian islands form as the Pacific plate
: Increasing temperature provides the energy for melting. Kauai) is farthest northwest
