Science is all about discovery, and learning why things happen. The world is full of mysteries and it takes a special person to desire to discover the answer to the world’s biggest mysteries. Scientists everywhere devote their time and energy to discovering information that will change how people view the Earth. One of the most important discoveries is how our continents were once together and how they divided. One of the earliest theories of how our continents were divided came from scientist Alfred Wegener in 1915. His theory suggested that the world had at one time been a single continent for most of geologic time (Pangea), but eventually, the continents separated and drifted away from each other. His theory was based on the hypothesis that the continents are made of lighter rocks that simply rest on the heavier crust material. Wegner stated that the positions of the continents are slowly moving at the rate of about one yard per century (Infoplease). Wegener’s theory of continental drift was based upon the knowledge that similar animal and plant fossils were found on completely different continents, similar geologic features and the fit of the continents. The problem with Wegener’s theory, was that he had no convincing evidence on how the continents moved. He proposed that the continents were moving through Earth’s crust, like “ice breakers plowing through ice sheets,” and that the force of the ocean was responsible for how the continents were moving apart.
