Divergent boundaries occur when plates are moving away from each other. These regions are known for the creation of new crust. Convergent boundaries occur when plates are moving towards each other. The denser plate sinks beneath the less dense plate, creating a subduction zone. These regions are known for mountain formation, earthquakes, and volcanoes. Transform boundaries occur when plates slide alongside each other. These regions are known for earthquakes. Other interesting features include hot spots, where a magma plume leaks through the oceanic crust to form a chain of islands; and supervolcanoes, which occur when magma builds up below continental crust and violently erupts.
