FALSE
The Hawaiian volcanoes come from a hot spot whereas the ring of fire volcanoes are from subduction zones. A hot spot is an area that was thought to be a relatively stationary plume of hot rock coming up from deep in the Earth's mantle. As the Earth's crust passes over the hot spot, the plume burns through it, creating volcanoes. Recent research shows that rather than being relatively stationary, these hot spots actually do move. How they move is a subject of current research. Subduction zone volcanoes come from the melting of the down-going plate.
Which of these volcanic eruption types is the least violent? B. Hawaiian A. Pelean B. Hawaiian C. Strombolian D. Plinian
If two plates converge and one goes under the other (subduction), then volcanoes can form at the point where the bottom plate is furthest into the area under the top plate, but this is sort of on plate boundaries. If a hot spot (abnormally hot area in the mantle under the crust) is in the center of a plate, it can still send up magma and cause volcanoes. A great example of this is the Hawaiian islands, which are in the center of the Pacific plate.
The Hawaiian volcanoes are shield volcanoes as they are broadly-sloping and composed of layers formed by basaltic lava flows.

The Hawaiian islands are made from volcanic eruptions. The active volcanoes in the circle of fire are to the south of Hawaii.

The shifting of plates in the earth cause massive underwaer volcanic eruptions. Over time, the eruptions of the volcanoes cause a buildup of dried lava that eventually breached the surface of the ocean. These volcanoes are still erupting, causing the island to gradually grow.
No. The Hawaiian islands are shield volcanoes.
one of the reasons why Plinian eruptions are more violent is that they release more viscous magma than Hawaiian hawaiian eruption.

Kaho'olawe is uninhabitable because the U.S. Military used it as a bombing range. True, most people would think it was from a volcano, but it was from the Military.
