Hot spot ^_^
All of the active and inactive volcanoes that are part of the Hawaiian-Emperor Seamount chain are shield volcanoes. Shield volcanoes are the result of Hot Spot volcanism which is the type of volcanic force that created the Hawaiian islands.
The Pacific Ring of Fire literally surrounds the basin of the Pacific Ocean, whereas the Hawaiian volcanoes are the result of the Hawaiian hotspot.See the related Wikipedia links for pictures and more information:
Igneous rock is a result of cooled lava or magma.
The Hawaiian Islands.
The island-arc volcanoes are formed from the subduction of an oceanic tectonic plate under another tectonic plate, and often parallel an oceanic trench.
Most volcanoes form at plate boundaries where melting of rock occurs in the upper mantle either as a result of thinning crust reducing pressure or from the introduction of volatiles.
The four states that are part of the Ring of Fire are Alaska, Washington, Oregon, and California. The Ring of Fire is, in general, where the Pacific Plate is subducting underneath some other plate. The result is a line of volcanoes along the subduction boundary. Hawaii, which was mentioned as an answer, is not part of the Ring of Fire because its volcanoes were formed by a hot spot.
Not really. Earthquakes can and do occur when a volcano is forming, but the volcano is not a result of an earthquake. Volcanoes are formed when magma (molten rock) within the earth's crust reaches the surface.
Some mountains, like volcanoes or hotspot mountains, form due to volcanic activity, not from the collision of continents. Examples include the Hawaiian Islands, formed by the movement of the Pacific Plate over a hot spot in the Earth's mantle, and Mount Kilimanjaro in Africa, which is a volcanic mountain formed independently of continental collisions.
The Hawaiian Islands were formed as a result of volcanic activity, specifically a hotspot that has been active for millions of years. As the Pacific tectonic plate moved over the hotspot, it created a chain of volcanic islands. The most active volcano in Hawaii, Kilauea, continues to add new land to the Big Island today.
They are formed in a very different way. Unlike usually Hawaii is on top of a "hotspot" or a very weak spot in the crust where the mantle breaks out, hardens and forms a volcano.
Igneous rock is the type of rock most commonly formed from volcanoes. igneous rocks may be formed from the magma underground, or form after the magma has ejected into the air. Underground, they can be formed when magma (molten rock) is trapped in small pockets and cools slowly over time. Above ground, igneous rocks are formed as the lava cools. Metamorphic rocks can be the result of volcanic activity, but they are not formed directly from volcanoes. Metamorphic rocks are the result of intense heat or extreme pressure transforming either sedimentary or igneous rocks, and these stresses can come from volcanic action, though that is not always the case.
