How do island arc volcanoes differ from hot spot volcanoes

An island arc forms at a converging plate boundary where one oceanic plate sinks beneath another oceanic plate. A hot spot volcano forms in continental or oceanic crust where magma from the mantle erupts. Hot spot volcanoes often are far from plate boundaries.

Explanation:

and convergent plate boundaries is were oceanic crust is often forced down into the mantle where it begins to melt. Magma rises into and through the other plate, solidifying into granite, the rock that makes up the continents. Thus, at convergent boundaries, continental crust is created and oceanic crust is destroyed.
