| This animation shows how hot spot volcanoes arise. A mantle plume beneath an oceanic plate creates a hot spot at base of lithosphere, and a volcano forms. Because the
hot spot remains fixed as the plate moves over it, this volcano eventually becomes extinct and a new one forms. In time, a chain of extinct volcanoes develops, with a live volcano over the hot spot as the last link in the chain. |
