Tectonic plate boundary types. Diagram showing four types of movement (arrows) at tectonic plate boundaries. Tectonic plates moving parallel to each other (top left) lead to strike-slip earthquakes with relatively little deformation. At a divergent boundary (bottom left), such as a mid-ocean ridge or rift valley, the plates move apart and molten rock rises to form new land. At convergent boundaries (right), such as a subduction zone (bottom right), one plate moves under the other as they collide (thrust or reverse faulting). This also leads to the formation of mountain ranges and volcanoes along the boundary as the subducting plate melts. If the subduction zone is destroyed there is continental collision (top right), which forms mountain ranges and knits the two continents together.
