Plate tectonics is the joining theory of the Earth. People thought that the Earth was cooling and shrinking like a prune would. One of the first well thought out idea for continental drift was the continents were moving and fit together like a jigsaw puzzle. If put together continents matched and fossils would also match.
             They fit the continents at the edge of the continental shelf, the shallow part of the continent that is found underwater. If matched together Africa and South America almost perfectly fit.
             Wegener wouldn't stop there though he also found that there was certain fossils in the ancient rock record that also match up when the continents are placed back together. Nobody would ever accept Wegener's ideas. But this was in the past and now we are looking into the future about what everything is going to be like.
             Sometime far into the future there is predicted to be another super continent. It is going to be called Pangaea Ultima. Africa will collide with Europe as Australia migrates North to merge with Asia. The Atlantic Ocean will probably widen for a spell before it changes course and disappears later. As you know millions of years ago the landmasses of Earth were joined into one super continent Pangaea. It is looking like it will be deja vu all over again. The Earths surface of the Earth is broken into large pieces that are shifting in a slow process called plate tectonics. We believe that Africa is going to keep heading North.
             Africa has slowly been colliding into Europe for millions of years. Italy Greece and almost everything in the Mediterranean is part of the African plate which has been colliding for 40 million years.
             In 50 million years form now Africa will have collided with Europe and close the Mediterranean off.
             The Americas will be moving further away from Africa and Europe as the Atlantic Ocean steadily grows.
             One of the reasons the plates are moving is because of the subduction...
