For 10 points, name this process by which one tectonic plate sinks into the mantle underneath another tectonic plate.
This process leads to the formation of a slab window, and volatile areas known as Wadati-Benioff (wah-DAH-tee BEN-ee-off) Zones are found in places where this process occurs. This process can cause orogeny, the formation of (*) mountains, as well as the formation of an island arc. It was responsible for the start of the 1960 Chilean earthquake, the largest ever recorded, as well as eight others of similar magnitude. This process occurs at convergent boundaries.
