Animation shows an Earth drained of water and stripped of vegetation revealing its cracked shell, or lithosphere, which is composed of more than a dozen tectonic plates. The large plate near the center is the North American plate. Magma in the mantle can be seen between gaps in the plates. Plate tectonics is the central mechanism behind the theory of continental drift. | |
