Our transcription: A third example, would be a continent-continent convergence zone or what we call a collision zone.

In this case what happened is that there used to be an intervening ocean basin, an oceanic plate being subducted or converging underneath one or both of the continents.

As the oceanic plate disappeared beneath the continent, the two buoyant continents collided, and you get this zone of a mountain range uplifted like the Himalayas or the Alps.

Typically what will happen is that convergence will stop along that zone.
