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.
However, post-World War II oceanographic evidence and development of plate tectonic theory in the 1960s have vindicated Wegener's basic conclusion that modern continents are drifted fragments of Pangaea. Introduction Wegener was an accomplished natural scientist in meteorology, astronomy and geology. He was a Greenland explorer and balloonist. He developed the hypothesis of drifting continents, a presursor to modern plate tectonics, but his ideas were not generally accepted until half a century later. Wegener was the son of an evangelical minister.
