    ultima?

    How do you know it will be the last one? Won't it split up and then reform again in another 400 - 500 million years?

      We have actually have four super continents in the history of the Earth and Pangea is only the most recent and most well known.

      Tass: To my memory Australia rifted off of Antarctica and has been heading north ever since. It is stilling heading north as we speak and it is moving faster then any continent on Earth. Eventually it will crash into the Indonesian volcanic archipelago and perhaps even the Philippine archipelago.

        Megacontinents are a trade off. You see the Earth's surface only has so many places for a continent to go and this leads to continents slamming into one another. The thing is if continents get to large the heat builds up underneath them and this leads to rifting along with spreading.

          Wasn't Italy part of the African plate and the Alps a result of the clash of this plate with the European one?

          And btw, the Northern supercontinent was called Laurasia and not Laurentia.

            Italy is actually what we call a microplate. Meaning it is a small continetal mass which moves as it's own plate. Other microplates such as the mideastern plate and the Central American plate exist.

            Laurasia and Laurentia are two different spellings for the same continent. It really depends upon who you speak to and where they are from as to which of the two names are used. In General Americans & Canadians use Laurentia while Europeans use Luarasia.

              Not sure if this is true. This source talks about both Laurasia (wrongly spelled Laurussia there) and Laurentia in a different context.

                I'd really have to pull out my old college text books but there were a great many ancient continents which were created and then broken up.

                  Fascinating. Asia — which is home to some of humanity's *oldest* nations — is, geographically, the *youngest* continent. Anyone sense a bit of irony here, or is it just me?

                    Most of China existed as a volcanic island arch in the tethese sea. A number of subplates docked in order to form the modern Asian content which is the youngest of the major continents.

                    P.S. I'm on my second bottle of Pinot Grigio so I hope people will understand any spelling errors.

                      Supercontinents are believed to form on a regular cycle ~ 500Ma or so. The thought is that the Pacific Ocean is more or less permanent whilst the Atlantic will eventually close up again. Once the oceanic crust flooring the Atlantic gets cold enough it will start to sink beneath Europe/Africa and the Americas, the continents will start to move together again and the ocean will close up.

                      As the earth cools, the rate of tectonic drift is slowing down.

                      By the time anything noticeable happens none of us will be around. Of more immediate interest is the likelihood of a magnetic polarity reversal during the next few hundred years. That is going to be very interesting indeed!
