Convergent Boundaries “Come Together” Continental-Continental Continental-Oceanic Oceanic-Oceanic

Continental-Continental Collisions two tectonic plates with continental crust collide

Geological Event: Mountains

Simon Says…

Continental-Oceanic Collisions a plate with oceanic crust and a plate with continental crust collide causing the denser oceanic crust to sink into the asthenosphere (this is called SUBDUCTION)

Geological Event: Trench

Oceanic-Oceanic Collisions two tectonic plates with oceanic crust collide, one is subducted under the other Older oceanic crust is more dense than newer oceanic crust causing the older crust to be subducted.
