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.
Tectonic Plates are huge, oddly shaped solid rock. They are mainly composed of oceanic and continental lithosphere. They connect together on the earths outer shell.
