Question

Which event is the most common at oceanic-oceanic convergent boundaries?

A.
island arcs

B.
rift valleys

C.
earthquakes

D.
volcanic mountain ranges

Answer 1

A subduction zone is formed at a convergent plate boundary when one or both of the tectonic plates is composed of oceanic crust. The denser plate, made of oceanic crust, is subducted underneath the less dense plate, which can be either continental or oceanic crust.

Answer 2

As a result of pressure, friction, and plate material melting in the mantle, earthquakes and volcanoes are common near convergent boundaries. When two plates move towards one another, they form either a subduction zone or a continental collision.
