Wegener believe that there was once a single supercontinent, which he called Pangea (or Pangaea). He said that Pangea broke apart millions of years ago to form two large continents. He called the one in the northern hemisphere Laurasia and the one in the southern hemisphere Gondwanaland.lfred Wegener, who was educated to be a meteorologist and an Arctic climatologist, insisted that his theory was correct because of the evidence he saw. To support his ideas about continental drift, Wegener pointed to the similarities in the fossils of the southern continents.
Wegener proposes idea of continental drift1912 Ever since the continents were all mapped, people had noticed that many coastlines, like those of South America and Africa, looked as though they would fit together if they could be moved like puzzle pieces. Alfred Wegener was one of those people. Though trained as an astronomer, he was a specialist on Greenland. He noticed that, based on nineteenth-century longitude determinations, it appeared that Greenland had moved a mile away from Europe in a hundred years.
