Subduction zone volcanoes typically have the most explosive eruptions. This is due to the accumulation of water and other volatile materials in the subducting tectonic plate, which leads to the generation of more viscous magma that can trap gas. In contrast, Hawaiian hotspot volcanoes and rift zone eruptions generally produce less explosive, basaltic lava flows.
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.
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 can form cinder cones, however the type of volcano they are classified as is shield volcano due to their broad sloping sides and the ability for their lava to flow.No. The Hawaiian islands are shield volcanoes.
Hawaiian volcanoes are primarily shield volcanoes, characterized by their broad, gentle slopes and fluid basaltic lava flows, which result in non-explosive eruptions. Unlike stratovolcanoes, which can produce explosive eruptions due to their more viscous magma, Hawaiian eruptions tend to create lava fountains and lava lakes. This is largely due to the hot spot volcanic activity beneath the Pacific Plate, which allows for consistent, less viscous lava production. Additionally, the unique geological setting of Hawaii contributes to the formation of extensive volcanic islands rather than typical volcanic mountain ranges.

Hawaiian volcanoes are shield volcanoes because they are characterized by their broad, gently sloping shape resembling a warrior's shield. This is due to the low viscosity of the basaltic lava they erupt, allowing it to flow easily and travel long distances before solidifying. As a result, shield volcanoes tend to build up gradually over time with successive eruptions, creating their distinctive shape.
No. The Hawaiian islands are shield volcanoes.
The Hawaiian islands are made from volcanic eruptions. The active volcanoes in the circle of fire are to the south of Hawaii.
Which of these volcanic eruption types is the least violent? B. Hawaiian A. Pelean B. Hawaiian C. Strombolian D. Plinian
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.
