Question

Earthquakes, volcanoes, Benioff seismic zones, and island arcs are all associated with oceanic trenches. Trenches occur at convergent plate boundaries where two plates are moving towards each other, and one plate is forced underneath the other in a process called subduction. The subducted plate melts as it gets deeper into the Earth's mantle, creating magma that rises to the surface and forms volcanoes. The friction between the two plates causes earthquakes, and the curved shape of the trench creates a Benioff seismic zone where earthquakes of different depths occur. Island arcs can also form above trenches when volcanic activity produces enough new land to rise above the water.
