Tectonic Plates of the Earth
Division of the Earth's surface into a mosaic of moving plates, according to plate tectonic theory. Boundaries between the plates are actively spreading submarine ridges in the middle of the oceans subduction zones in ocean trenches or mountain ranges on the continents, or margins where the plates slide past one another. Most of the world's earthquakes occur at plate boundaries.
