Volcanoes
Hot spots- a small area or region with a relatively hot temperature in comparison to its surroundings. High heat and lower pressure at the base of the lithosphere (tectonic plate) facilitates melting of the rock And an area in the mantle from which heat rises as a thermal plume from deep in the Earth.
Ring of fire- a major area in the basin of the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur. In a 40,000 km (25,000 mi) horseshoe shape, it is associated with a nearly continuous series of oceanic trenches, volcanic arcs, and volcanic belts and/or plate movements.
