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 gathered evidence from different scientific fields to support his ideas about continental drift. He studied land features, fossils, and evidence of climate change. In 1915, Wegener published his evidence for continental drift in a book called The Origin of Continents and Oceans. Evidence From Land Features As shown in Figure 12, mountains and other features on the continents provided evidence for continental drift. For example, when Wegener pieced together maps of Africa and South America, he noticed that mountain ranges on both continents line up.
