The collision of two oceanic crusts causes the formation of an island arc as one is forced to move over the other.

Oceanic-oceanic collision occurs when two tectonic plates carrying oceanic lithosphere collide with each other. This collision often leads to the subduction of one plate beneath the other, resulting in the formation of volcanic island arcs and deep oceanic trenches. The collision can also lead to the formation of new oceanic crust through volcanic activity.
At a convergent boundary, three types of collisions can occur: oceanic-oceanic, oceanic-continental, and continental-continental. In an oceanic-oceanic collision, one oceanic plate subducts beneath the other, forming a deep ocean trench. In an oceanic-continental collision, an oceanic plate subducts beneath a continental plate, creating volcanic arcs and mountain ranges. In a continental-continental collision, both continental plates crumple and fold, forming high mountain ranges.

Collision boundaries can be found along tectonic plate boundaries, where plates either converge (subduction zones), diverge (mid-ocean ridges), or slide past each other (transform faults). These boundaries result in different types of collisions, such as continental-continental, oceanic-oceanic, or continental-oceanic collisions, which can lead to the formation of mountain ranges, earthquakes, and volcanic activity.
Continental crust cannot form as a result of oceanic-oceanic convergence. This process typically results in the formation of volcanic island arcs or deep-sea trenches. Continental crust is formed through processes like continental collision and accretion of terranes.
