Volcanic arcs are formed as a more dense oceanic plate collides with a less dense oceanic plate, subducts, and creates molten material which rises through the overriding plate, which in turn creates submarine volcanoes. The volcanoes may grow until they eventually breach the surface of the water, producing volcanic arc landmasses.

What is the differences between volcanic island arcs and volcanic arcs?
Volcanic arcs form at plate subduction zones. Island arcs are volcanic islands that form over "hot spots" in the Earth's mantle. Because the islands are moving with the oceanic plate, they eventually are removed from the hot spot, forming a chain of islands in the direction of the plate movement.

Is a volcanic arc the same thing as a volcanic mountain range?
Volcanic arcs are usually island arcs off the coast of a continent, while volcanic mountain ranges are usually inland inside a continent. But the volcanoes of a volcanic island arc do form an undersea volcanic mountain range. So to some extent the difference is mostly a matter of terminology.
What do convergent boundarys form?
They form landforms such as trenches, islands and volcanic mountains.
What features form at a hot spot.?
They form volcanic mountains by heating magma that breaks through the crust. On the oceanic plates, these crustal hot spots can form chains of volcanic islands such as the Hawaiian Islands.

Where do volcanic arcs form?
About 150km from a subduction zone.

How did the santorini volcano form?
Santorini volcano was formed by the conversion of the African plate and the Aegean Sea Plate. As subduction occurred, some magma burned to the surface and create volcanic islands called island arcs. Santorini is one of those volcanic islands.
What forms at a subduction zone?
Volcanic arcs and oceanic trenches commonly form at subduction zones.
What causes the formation of the chain of volcanic island?
A convergent plate boundary where two tectonic plates of oceanic crust meet, and the denser of the two subducts below the other. The water content of the subducting crust lowers the melting point of the rocks around it and a pool of lighter molten rock rises to form characteristic volcanic island arcs such as the Aleutian Islands in Alaska.

How did the Sandwich Islands form?
By volcanic activity,
What plate boundary are volcanic islands?
Volcanic islands typically form near subduction zone, but they can also form at hot spots, which are not associated with plate boundaries.
Is a volcanic island transform?
No. Volcanoes do not form at transform boundaries. Volcanic islands can form at convergent boundaries and at hot spots.
What features form at a hot spot.?
They form volcanic mountains by heating magma that breaks through the crust. On the oceanic plates, these crustal hot spots can form chains of volcanic islands such as the Hawaiian Islands.
