The Intertropical Coverance Zone. Or to abbreviate, ITCZ.
Most of the Earth's volcanism occurs along the mid-ocean ridges where new crust is being continually produced, resulting in the movement of continents. Other volcanoes occur where cold dense oceanic crust is being subducted under less dense oceanic or continental crust. The most notable example of this is the Pacific Ring of Fire, an area of volcanism following the subduction boundary of the Pacific Plate. The subducted crust melts and rises toward the surface, producing undersea or surface volcanoes. A third location for volcano production occurs at so called 'hot spots' in the Earth's mantle, where rising plumes of magma that originate deep within the mantle burn through the crust, resulting in land based or underwater volcanoes.
There are 2 locations where volcanoes occur:
- along plate boundaries
- at mantle hotspots
Generally, volcanoes are located near tectonic plates that are converging or diverging.
