Evidence of continental`drift`

The determined age of the Earth as 2 billion years opened doors for theories of continental movement during this vast amount of time.[25] In 1912 Alfred Wegener proposed the theory of Continental Drift.[26] This theory suggests that the continents were joined together at a certain time in the past a ...

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.
