How does a hot spot supervolcano form? How hot is the magma chamber in a volcano? Why are there so many volcanoes in Hawaii? How are volcanoes distributed? What fuels the volcanoes at Hawaii? What kind of volcanoes are the Hawaiian islands?
There are a few continental ridge areas, where the magma does spew out onto land; but most land volcanoes are produced by subduction zone volcanism and hot spot volcanism. When the solid rock changes form to a more liquid rock material, it becomes less dense than the surrounding solid rock....

A volcano above a hot spot does not erupt forever. Attached to the tectonic plate below, the volcano moves and is eventually cut off from the hot spot. Without any source of heat, the volcano becomes extinct and cools.Can a volcano erupt without warning?
Since 1872, Yellowstone National Park has been protected land with beautiful natural wonders which now attract millions of visitors. However, the park has a huge, terrifying secret: It's an active supervolcano and one of the largest volcanic systems in the world. ...
Why are the Rocky Mountains called a continental divide? How is Yellowstone's supervolcano different from most other volcanoes? How are the LOCATIONS of volcanoes related to the Earth's plates? Why do big mountains form during continental colli...
Yellowstone sits above a spot in the Earth's mantle where columns of hot, molten rock called plumes rise to form volcanoes in the planet's crust. This spot is called a hotspot, and it creates atype of volcano not associated with a plate boundary. Yellowstone has produced three calderatypes...
