WebA narrow chain of explosive, rhyolite volcanoes forms on the surface of the moving plate. The areas of rhyolite underlying the Snake River Plain form discrete areas of volcanic activity, rather than one long ridge. This situation is analogous to that seen in the Pacific Ocean, where discrete islands form over the Hawaiian Hotspot. WebHotspots are places where the magma rises up through the crust. They are caused by a static source of magma, often away from plate margins. As the plate moves away from …

"WebA hotspot forms when a plume of magma rises from the mantle and melts through whatever crust is above it. This new magma tries to reach the curface and creates a volcano. But when the tectonic plate shifts, new crust is suddenly above the hotspot, and a new volcano forms. This is how hotspot volcanoes form. How do islands form? " - How do hotspot volcanoes form

WebApr 14, 1995 · The sinking plate melts to form magma, which rises and forms volcanoes on the overriding plate. This process forms the ring of volcanoes around most of the Pacific Ocean. Where two plates move apart, magma rises and fills in the space. This kind of volcanism occurs deep on the ocean floor. WebMay 24, 2010 · There are three main places where volcanoes originate: Hot spots, Divergent plate boundaries (such as rifts and mid-ocean ridges), and Convergent plate boundaries (subduction zones) The origin of the magma for hot spots is not well known.

WebThere are two main ways Earth materials melt: 1) hot mantle rises and decompresses; and 2) water flows through hot rock. The first type of melting occurs at diverging plate boundaries (mid-ocean ridges; continental rift zones) and hotspots, where mantle beneath plates is hot but remains solid because it is under great pressure. WebVolcanic hot spots are plumes of molten rock which rise from the mantle and cause the crust to melt, creating magma resulting in volcanic activity.
