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.
Wegener went further by developing his âContinental Driftâ theory. Wegenerâs Continental Drift theory, although inaccurate, paved the way for the modern theory of plate tectonics. Wegener suggested that the continents had, in the past, all been joined together into a giant super-continent â which was later labelled as Pangea (Ancient Greek for Entire Earth) and that continents were moving away from each other toward the equator due to centafugal force from the earths rotation.
