Front

Explain the theory of plate tectonics.

Back

The theory of plate tectonics explains that the Earth's outer layer, or crust, is divided into large, rigid pieces called tectonic plates. These plates fit together like a giant jigsaw puzzle on the Earth's surface, floating on a layer of semi-molten rock beneath them called the mantle. Because of heat coming from deep inside the Earth, these plates are slowly moving, even though we can’t feel it.
