17 Dec 2014 The melted rock, known as magma, often pushes through cracks in the crust to form volcanoes. Hot spot volcanism is unique because it does not occur at the boundaries of Earth's tectonic plates, where all other volcanism occurs. Instead it occurs at abnormally hot centers known as mantle plumes.
2 Jul 2010 Scientists had thought that volcanoes always erupted along the rifts that form when the Earth's plates break apart, such as when the
Volcanoes form when hot molten rock called magma rises to the surface. Sometimes, though, a volcano can form over a hotspot. A hotspot is a place in the middle of a tectonic plate where hot magma rises. It may start where there is a "bump" in the mantle.
A leak in the mantle lets molten magma flow out and through the crust, forming volcanoes. But the plates move, and the magma keeps flowing
A hot spot develops above the plume. Magma generated by the hot spot rises through the rigid plates of the lithosphere and produces active volcanoes at the
The Hawaiian Emperor seamount chain is a well-known example of a large seamount and island chain created by hot-spot volcanism. Each island or
Hot spot volcanoes are formed by pressure building up and pushingmolten lava up till the earth cracks and lava pours out and thenthe lava drips down the
In geology, the places known as hotspots or hot spots are volcanic regions thought to be fed by The latter form over subduction zones, at converging plate boundaries. are not time-progressive (e.g. the Galapagos) and by the fact that hotspots do not appear to be fixed relative to one another (e.g. Hawaii and Iceland.)
When a hot spot forms in the middle of a plate, it remains constant, as the plate continues to move over it. The result is that a trail of volcanoes is left behind, with
