Pangea began to break up about 200 million years ago in the same way that it was formed: through tectonic plate movement caused by mantle convection. Just as Pangea was formed through the movement of new material away from rift zones, new material also caused the supercontinent to separate.
Explanation:
Today, tectonic plates continue to slowly slide around the surface, just as they have been doing for hundreds of millions of years. Geologists believe the interaction of the plates, a process called plate tectonics, contributed to the creation of continents.
