What is a tectonic plate? A tectonic plate (also called lithospheric plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere. Plate size can vary greatly, from a few hundred to thousands of kilometers across; the Pacific and Antarctic Plates are among the largest.
Plate tectonics is the geologic theory that Earth's crust is made up of rigid plates that float on the surface of the planet. Tectonics comes from the Greek word meaning builder. The movement of the plates toward or away from each other either directly or indirectly creates the major geologic features at Earth's surface. Plate tectonics revolutionized the way geologists view Earth. Like the theory of evolution in biology, plate tectonics is the unifying concept of geology.
