Convergent and Divergent Boundaries

Diverging means that the plates are pulling apart, and convergent boundaries means squishing together. All of the continents look like jigsaw puzzle pieces that fit together.Divergent boundaries are responsible in part for driving the motion of the plates, and Convergent Boundaries are responsible for explaining why crust older than the Cretaceous cannot be found in any ocean basin: it has been destroyed by the process of "subduction".


Convergent Boundaries

Convergent Boundaries create large mountain ranges. The Himalayas formed from a convergent boundary.




Divergent Boundaries
Divergent Boundaries create volcanic islands.

  1. Divergent plate boundaries do not create volcanic islands. Rather, volcanic islands chains typically occur in an "island arc" as a result of water fluxing within a subduction zone. Subduction zones are associated with CONVERGENT, not DIVERGENT plate boundaries.

    An example of a divergent boundary would be the Mid-Atlantic ridge, or the East African Rift. These do not create islands- they create new basaltic oceanic crust.
