The story of plate tectonics begins with the German scientist Alfred Wegener in the early part of the twentieth century. He first proposed that the continents had moved and were still moving. He pointed 1 out a line of mountains that appears from east to west in South Africa. Then he pointed out another line of mountains that looks almost exactly the same in Argentina, on the other side of the Atlantic Ocean. He found fossil 2 remains 3 of the same kind of an early plant in areas of Africa, South America, India, Australia and even Antarctica. Alfred Wegener said the mountains and fossils 4 were evidence that all the land on Earth was united at some time in the distant past. Wegener also noted 5 differences between the continents and the ocean floor. He said the oceans were more than just low places that had filled with water. Even if the water was removed, he said, a person would still see differences between the continents and the ocean floor. Also, the continents and the ocean floor are not made of the same kind of rock.
