What Are Some Examples of Convergent Boundaries?

A convergent plate boundary occurs when a collision of tectonic plates causes one plate to slide over the top of another. There are three examples of convergent plate boundaries that occur as the result of continental and oceanic plate convergence:

Continental vs. Oceanic Convergence When a continental plate and oceanic plate collide, the more buoyant continental plate slides atop the oceanic plate, creating a subduction zone that features deep ocean trenches and volcanic mountains.

Oceanic vs. Continental Convergence When two oceanic plates collide, whichever plate is older (and thus denser) will be covered by the other, newer plate. These collisions result in the creation of volcanic mountains that can surface above the ocean as small island chains.

Continental vs. Continental Convergence When two continental plates collide, neither can "sink", because buoyancy is not a factor. Instead the pieces are crammed together, creating large mountains, such as the Himalayans.
