at which type of plate boundary would a string of small volcanic islands most likely form?

Question

transform boundary
divergent ocean-ocean boundary
convergent ocean- continental boundary
convergent ocean-ocean boundary

Answer 1

A string of small volcanic islands would most likely form at a convergent ocean-ocean boundary. This type of boundary occurs when two oceanic plates collide, leading to the subduction of one plate beneath the other. As the subducting plate sinks into the mantle, it melts and creates magma, which can rise to the surface and form volcanic islands. This process is responsible for the formation of island arcs, such as the Aleutian Islands in Alaska or the Marianas Islands.
