In 1912, Alfred Wegener, a German meteorologist and geophysicist, outlined his hypot hesis for œcontinental drift. This hypothesis challenged a long-held assumption that the continents and ocean basins had fixed geographic posit ions (i.e., they didn’t move). Explain the continental drift hypothesis. Describe two lines of evidence Wegener used to support his continental drift hypothesis. What was the main flaw with Wegener’s continental drift hypothesis?
