I learned a lot more on what Pangaea was really like as well as how it could really be true due to similar formations throughout the continents. Plate Tectonics are pretty crazy, knowing that they have the ability to move continents is almost scary because all it would take is another instance like Pangaea and we would all be in trouble. I believe that the theory of sea floor spreading is the most accurate in terms of what really happened to cause the continents to shift. I also believe that all of the theories are linked together and cumulatively as a whole. It seems to me that having magma come up through the earth and harden causing the plates to spread it very believable. I believe that scientists of different studies share information either through various publishing's in a science journal or through a common info. sharing thing. I believe that it is almost irrefutable that the continents as we know them today were all at on point, one large land mass. The evidence that supports it is far beyond that which states that it didn't happen. The various theories on how it happened is a different story. They are all fairly believable and seem to all have happened. I don't think that any of the theories could have occured without the occurance of the others.
