What ocean formed when Pangaea broke apart? Over millions of years, the continents broke apart from a single landmass called Pangea and moved to their present positions. Each continent has at least one large area of very old rock exposed at its surface called the shield. Today, we know that the continents rest on massive slabs of rock called tectonic plates. Some 100 million years later, Pangaea began breaking apart. They found that while there was global cooling in Earths early years, the outer shell was warming at the same time, which is the most likely cause behind our planets crust breaking apart. Just as Pangea was formed through the movement of new material away from rift zones, new material also caused the supercontinent to separate. Wegener suggested that perhaps the rotation of the Earth caused the continents to shift towards and apart from each other. But before Pangaea, Earths landmasses ripped apart and smashed back together to form supercontinents repeatedly.
