Plate tectonics. Artwork showing plate tectonics around an ocean basin. The Earth's crust is made up of tectonic plates that move on top of molten rock (red/yellow). Continental rock (light brown) rides on top of heavier rocks (purple-brown) that also make up the ocean basins. New ocean rock is formed at mid-ocean ridges (centre). This leads to sea-floor spreading and the drifting apart of the continents. Two subduction zones,one offshore (left) and one coastal (right) show where oceanic rock being pushed under the continental plate is destroyed,forming volcanoes.
