How hot is Mount Vesuvius? lava? How do seismometers predict volcanic eruptions? How do volcanoes change their local landscape? How does a hot spot supervolcano form? How hot is the magma chamber in a volcano? Why are there so many volcanoes in Hawaii?
The Hawaii volcanoes were created by such a hot spot, which appears to be at least 70 million years old. So what happens to the magma formed by these processes? We saw that the magma produced at ocean ridges just hardens to form new crust material, and so doesn't produce spewing land ...

Why do volcanoes not form at continental collision boundaries? What causes coastal volcanic mountains? Explain formation of volcano mountains. How does a fissure volcano form? What causes hot spot volcanoes? How do plate tectonics cause major geological events?
to open up at weak spots in the crust, and it's through these cracks that magma pushes up to form volcanoes. Proponents of the crack hypothesis consider this a widespread phenomenon and believe that magma's not coming up from deep within the Earth's interior, but rather from just beneath...
Volcanism is another way mountains can arise. Subduction zones often hostvolcanoes, leading to island arcs such as the isles of Japan,according to James Madison University's geology department. In addition, giant pillars of hot rock known as mantle plumes can rise from near Earth's core to sea...
First of all, volcanoes are the reason Iceland exists.The area where volcanic activity has created the island over 18 million years rests on a constructive plate boundary called the Mid-Atlantic Ridge, which is part of one of the world's longest mountain ranges (albeit underwater) at nearly...
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....
Do volcanoes erupt forever?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?
you do not bring your daily mindset with you—and when you return from the spiritual realm, you clearly remember the gifts and lessons and wisdom you have received. Steiner represents this in the form of some guardian, which is rather demanding when people make this back-and-forth transition...
