kidmore T urner 111412 1 st period Wegeners Theory A German scientist named Alfred Wegener proposed a hypothesis called the continental drift Alfred Wegener hypothesized that the continents once were all together in one mass this was called the super continent Over millions of years his hypothesis became a reality the super continent began breaking away into smaller continents over a .
