Summary

Scientists don’t know for sure that Mesosaurus is a freshwater animal. Some scientists think that maybe it could’ve swam across the salt-water ocean. There are no links that prove why it’s a freshwater animal. As for I don't believe in Alfred's theory of the continental drift also because I believe that the entire plate is moving not just the land masses.

Summary

I believe that seafloor spreading is what actually happens because of the evidence we have. Such as the new and old rocks found on the seafloor. The evidence that is given above proves a lot about Harry Hess's theory of Seafloor Spreading. It talks about the young and old rocks found on the seafloor and what cause Seafloor Spreading to happen. As for I agree because what Harry Hess has come to find with his theory happens to be somewhat true.

Summary

I somewhat agree with the plate tectonic theory. There was a lot of evidence given to show that this theory was really trying to be proven. Out of the three theories that are talked about I believe this one the most. We don't know for sure this is happening because we've never seen it, but it makes the most sense and doesn't have anything against it. When we have earthquakes, the earth can't just be moving with nothing pushing it. This theory is the one that is the most true out of all three theories given.
