When an oceanic plate ______ (collides, diverge) with a continental plate

the crust forming the oceanic plate gets bent and pulled under the

continental crust. The process by which the oceanic crust is pulled under the

continental crust is called ________ (convection, subduction). At the

subduction zone where the oceanic crust sinks beneath the continental crust

a deep oceanic _____ (trench, ridge) is created.

Oceanic and oceanic plate convergence result in the formation of ______

(mountain, volcano). The crust that is pulled under or subducted melts to form

_____ (magma, lava). It rises to the top of the overriding oceanic plates and

erupts on the ocean floor. Over millions of years, the lava and debris from the

volcanic eruptions pile up on the ocean floor until the volcano rises above

sea level to form a ________________ (mountain ranges, volcanic island).

When a divergent boundary occurs beneath oceanic lithosphere, the rising

hot molten materials below lifts the lithosphere, producing a ________________

(rift valley, mid-ocean ridge). ___________________ (East African rift valley,

mid-ocean Atlantic ridge) is a classic example of this type of plate boundary.

A transform fault is formed between two _____ (similar, different) plates,

each moving away from the spreading center of a ________ (convergent,

divergent) plate boundary. A smaller number of transform faults cut

continental lithosphere. The most famous example of this is the ______ (San

Andreas, East America) Fault Zone of western North America​
