I had previous knowledge of Pangea, without knowing the name, but I knew that all of the continents were once in a big jumble. I did not know where the continents were placed though, which I learned through this activity. I learned of how the continents moved with the theory's of Wegner, Hess, and whoever else came up with the last one.
I assume scientists publish their findings, and if a scientists of a different nature disagrees with their findings then they show the proof to disprove it. For instance, Wegner's idea of Continental Drift was based on his scientific studying, but Hess had a different scientific expertise and had proof to disprove Wegner's theory.
