The mission you are about to receive may horrify, if may scar you for life... nah I'm just kidding! Anyways, do you know who had the first theory of plate tectonics? You probably don't know and don't care. Today my mission is to impress you with the theory of plate tectonics and who discovered it.. Plate tectonics is the idea that part of the crust and upper mantle is consisted of huge plates that move gradually. Do you know how first thought of this theory? His name is Alfred Wegener.

Nice mustache... |
No ones hair is that slick! I mean really... At first when Wegener presented his idea of plate tectonics, the other scientists laughed at him, and not just because of his hair. They laughed because this theory is extremely hard to believe. I mean huge plate that move under the earth and cause earthquakes? I could see why others laughed. Plus, he had no evidence. Well, only a little.
His evidence was called continental drift ( which the other scientists didn't believe either.) This was the idea that about 200 million years ago, the continents were all part of one super continent called Pangaea. Eventually, the continents begin to move apart and go into the shape we know today. Here is what he said to other geologists:
"Doesn't the east coast of South America fit exactly against the west coast of Africa, as if they had once been joined?"
