How does a hot-spot supervolcano (such as Yellowstone) form?
How hot is the Yellowstone hotspot? At 80 kilometres beneath the Earth's surface it's about 1450 °C, say researchers - which, for a supervolcano, is only lukewarm.That doesn't mean we won't get http://wiki.answers.com/article/dn12896-magma-surge-causes-record-rise-at-yellowstone.html. The last explosion, some 642,000 years ago, created the Yellowstone caldera and http://wiki.answers.com/article/mg18925345.100-how-a-supervolcano-covers-a-continent.html.

When was Yellowstone supervolcano formed?
The Yellostone volcano as it currently is formed about 2.1 million years ago. The hot spot that produced it has produced a chain of supervolcanoes, all of which are extinct apart from the current one in Yellowstone.

How do island chain form?
well, there is a hot spot that exploes making a landform, then the pacific plate caries it away form the hot spot, and this process repets.
Is old faithful really a supervolcano?

Why does magma form at a hot spot?
Magma form at a hot spot due to a focusing of conditions that lead to melting. This is sometime caused by a mantle plume, but is NOT always the case.
What features form a hot spot?
