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.
One of the main problems with Wegener's theory was that he believed that the continents plowed through the rocks of the ocean basins. Most geologists did not believe that this could be possible. In addition, Wegener did not have an acceptable theory of the forces that caused the continents to drift.ince the continents floated on the plates, the Plate Tectonic Theory provided the needed mechanism for Wegner's Continental Drift. At once it was readily accepted by most all geologists. On another note, Wegner used the jigsaw puzzle analogy as one of the evidences of his theory.
