Continental Drift & Plate Tectonics

Continental Drift & Plate Tectonics. Is this SERIOUSLY happening????. http://www.uwsp.edu/geo/faculty/ozsvath/images/continental%20fit.jpg. If you take a look at a globe, you can see that if we were to squish the land all together, most of the continents seem to fit together like a puzzle.
