A subduction zone is the biggest crash scene on Earth. These boundaries mark the collision between two of the planet's tectonic plates. The plates are pieces of crust that slowly move across the planet's surface over millions of years. Where two tectonic plates meet at a subduction zone, one bends and slides underneath the other, curving down into the mantle. (The mantle is the hotter layer under the crust.). Tectonic plates can transport both continental crust and oceanic crust, or they may be made of only one kind of crust. Oceanic crust is denser than continental crust. At a subduction zone, the oceanic crust usually sinks into the mantle beneath lighter continental crust.
Another example, forming the northern rim of the Ring of Fire, is the Aleutian trench shown here: The Pacific plate descends into the mantle at the site of the Aleutian trench. Subduction zone volcanism here has generated the Aleutian island chain of active volcanoes.Courtesy of NOAA.sland arc formed by oceanic-oceanic subduction Volcanic arc formed by oceanic-continental subduction.
