All of the evidence suggests that 225 million
years ago all of the land masses of earth were
locked together as a great supercontinent called
Pangaea, a Greek word meaning all lands.
Panthalessa, Greek for all seas, was
the name given to the resulting world ocean. Eventually,
tectonic forces caused the break-up of Pangaea,
leading to the current, albeit temporary, arrangement
of oceans, continents, and other land masses.
Scientists believe that the Earths crust
has been undergoing these transformations for
most of its 4.6 billion year history. Two
hundred million years from now a new Pangaea will
be formed when all lands again converge. Then,
inevitably, another break-up will ensue as our
restless planet continues to reform and reshape
itself.
