The huge slabs of continental or oceanic crust that fit together along their edges are called tectonic plates. The Earth's lithosphere, which includes the crust and the upper mantle, is broken into these large pieces. Tectonic plates can contain both oceanic and continental crust, and they move atop the asthenosphere—a semi-fluid layer of the mantle—due to the heat-driven convection currents below. The movement and interaction of these plates can cause earthquakes, volcanoes, the formation of mountains, and the creation of oceanic trenches.
