Finding fossils of the Mesosaurus on the southern hemispheres of both continents is a further indication that the two continents were once together and later drifted apart. This rock then spreads out and cools, sinking back towards the core, where it can be heated again. Thermal convection occurs as hot rock in the deep mantle rises towards the Earths surface.

Find a map of the continents and cut each one out. Pangaea Wegener was convinced that all of Earths continents were once part of an enormous, single landmass called Pangaea. A more popular name for this huge ancient landmass is Pangaea, which means all lands in Greek. Undoubtedly, this interpretation is in complete disagreement with Darwins evolution theory. The continents moved by centrifugal and tidal forces. Support for Continental Drift. Over the course of millions of year ago, this gradual . Sea floor spreading indicates that since the continents presently move apart, previous continental drift was possible and probable as well. The fossils of the reptiles Mesosaurus and Lystrosaurus and a fernlike plant called Glossopteris have been found on widely separated landmasses. The gold-bearing veins are in Brazil and it is obvious that the gold deposits of Ghana are derived from the Brazil plateau when the two continents lay side by side. Heat coming from the interior of the earth triggers this movement to occur through convection currents inside the mantle. The continents remained fixed and the north magnetic pole moved. The theory of continental drift is most associated with the scientist Alfred Wegener. The four pieces of evidence for the continental drift include continents fitting together like a puzzle scattering ancient fossils rocks mountain ranges and the old climatic zones' locations.

What is continental drift theory explain? Now if the continents were in still their present positions, there is no possibility that the Mesosaurus would have the capability to swim across such a large body of ocean as the Atlantic because it was a coastal animal.
