New oceanic lithosphere forms as a result of continental drift.
Just as new oceanic crust forms at mid-ocean ridges, old oceanic crust is destroyed at subduction zones.
An island arc forms.

basalt forms in oceanic crust granite forms in continental
mid ocean ridge
Ridges of buoyant oceanic crust form at diverging oceanic plate boundaries.
it forms a trench
They form when the oceanic crust goes under the Continental crust. The oceanic crust then forms the trenches through a process called subduction.
the colder,oceanic plate sinks?!?!
Rift valleys
