The Hawaiian Islands and many other volcanic islands in our oceans were formed by a hot spot situated under the middle of a tectonic plate. It is beneath the center of the plate, and, therefore, it does not move as the plate moves. It is a magma source, and magma spews out of it onto the Earth's surface on the plate to form lava mountains, eventually rising high enough above the sea to become volcano islands. These volcano islands are situated above the plate, so they move along with the plate when it continues its movement. Since the hot spot does not move, the volcano on the island is no longer above the hot spot and therefore becomes extinct as it is cut off from its magma source. In time, a new volcano island then forms on top of the hot spot in the new location on the topside of the plate that is now situated over the hot spot, and the cycle continues creating more volcanic mountains and islands.
