Interesting Fact:

While many people throughout history have reflected on the mobile nature of the earth's surface, one of the first scientists to put forward a well-documented proposal for the large-scale motion of continents was a German meteorologist named Alfred Wegener. He compiled various lines of evidence supporting the hypothesis that all of earth's continents had been assembled as a single "supercontinent" approximately 250 million years ago.
