"That is how the plates formed at the surface of the Earth," Catherine Rychert, a geophysicist at the Woods Hole Oceanographic Institution in Massachusetts, told Live Science. "The plate is the crust, then a bit of the mantle beneath it …. Beneath that you have weaker material." This ...
1.1 Definition: Tectonic plates are large sections of the Earth's lithosphere that float on the semi-fluid asthenosphere beneath. 1.2 Composition: These plates are composed of both continental and oceanic crusts, along with the underlying uppermost mantle. II. Plate Tectonics Theory 2.1 Development:...

Discover the pieces of the Earth's crust known as tectonic plates. Explore the layers of the Earth, how tectonic plates move by convection currents in the mantle, the Plate Tectonic theory, and the landforms created by plate tectonics.
