Answer:seen below
Explanation:
The effects of an ocean-ocean subduction zone are the same as those of an ocean-continent subduction zone in that, the subduction zone where an oceanic plate subducts beneath another oceanic plate are the same as a continent-ocean subduction zone.
They oceanic plate and the continental plate are both convergent zones, but when an oceanic plate converges with a continental plate, the oceanic plate is forced underneath the continental plate this is because oceanic crust is thinner and denser than the continental crust. The difference is that the volcanic arc formed will be a set of islands known as an island arc.
If two plates meet at a convergent plate boundary both are of oceanic crust, the older, denser plate will subduct beneath the less dense plate into a trench, resulting in earthquakes.
Finally, When two continents meet head-on, neither is subducted under, this is because the continental rocks are relatively light and are like two colliding icebergs they resist downward motion. Instead, the crust tends to buckle and be pushed upward or sideways.
