  • Continental Drift and Plate Tectonics | Let's Talk Science

    In the Theory of Plate Tectonics, it is tectonic plates, rather than continents, which are moving. Tectonic plates are pieces of the lithosphere and crust, which float on the asthenosphere. There are currently seven plates that make up most of the continents and the Pacific Ocean.
