placa continental

A rigid, primarily granitic slab floating on the asthenosphere, a layer of semi-molten upper mantle. The plates average 125 kilometers of thickness and are pushed rather than pulled by currents in the mantle. (See Plate Tectonics. ) The continents riding atop the plates occupy 29% of the planet surface.
