... Convection currents carry the plates of the earth’s crust in a piggy-back motion. The plates collide at boundaries of collision or destruction. Most volcanoes form at two types of destructive plate boundaries: (a) where an ocean plate collides with a continental plate; and (b) where two ocean plates ...

Pangaea
Pangaea or Pangea (/pænˈdʒiːə/) was a supercontinent that existed during the late Paleozoic and early Mesozoic eras. It assembled from earlier continental units approximately 300 million years ago, and it began to break apart about 175 million years ago. In contrast to the present Earth and its distribution of continental mass, much of Pangaea was in the southern hemisphere and surrounded by a super ocean, Panthalassa. Pangaea was the last supercontinent to have existed and the first to be reconstructed by geologists.
