Final answer:
A subduction zone is the location where one tectonic plate is being forced beneath another, creating a volcanic arc.
Step-by-step explanation:
A subduction zone is the location where one tectonic plate is being forced beneath another, creating a volcanic arc. In general, subduction zones occur where one oceanic plate is forced beneath another plate, which can be either oceanic or continental.
An example of a subduction zone is the deep Japan trench along the coast of Asia, where the Pacific Plate is subducting beneath the Eurasian Plate. In this process, the subducted plate is forced into regions of high pressure and temperature, eventually melting and forming molten rock that rises to the surface, leading to the creation of volcanoes.
