Bananas are great sources of potassium, but eating one of these yellow fruits won't be enough to supply your body with the recommended daily intake (RDI) of this important mineral.
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.
It was only early scientists like Galileo who needed to fear the reaction to their radical views. Neither of these beliefs is true. The reaction to Alfred Wegener's Continental Drift Theory demonstrates that new ideas threaten the establishment, regardless of the century.Alfred Wegener was the scientist who proposed the Continental Drift Theory in the early twentieth century.Simply put, his hypothesis proposed that the continents had once been joined, and over time had drifted apart.egener really did not believe that he had the explanation for the mechanism, but that this should not stop discussion of a hypothesis. Wegener's contemporaries disagreed. A major conference was held by the American Association of Petroleum Geologists in 1926 that was critical of the theory.
