Continental Drift

Throughout the "Dancing of the Continents" activity, I learned that all of the continents fit together perfectly. they all connect in certain places as if they belong all clustered together. The continents all broke apart because the ocean floor did not have enough strength to hold them all together. The Theory of Continental Drift was proposed in 1920. It was not believed by some people until proved by seafloor spreading. Magma from beneath the earths crust could fill in, between the plates. The hot magma cooled in the ocean water, it would expand and push the plates on both sides. The Atlantic Ocean would then become wider, but the coastlines of the land masses would not change. The Theory of Plate Tectonics was said that all seven  continents broke apart and split up. this theory was proposed and later proven. It showed those people who doubted this theory that it was actually true. Scientists of different disciplines collaborate by sharing their information and putting it together with other information to see if it matches. The scientists come together with each other and use everything they found to try to prove their theories and observations.
