Answer:
A subduction zone is a region in which an oceanic tectonic plate slides beneath a continental plate. This action creates volcanic islands and volcanoes along the coasts of continents. It can also generate large earthquakes. If these earthquakes occur offshore in the ocean, they may even generate a tsunami. The oceanic plate also melts during the subduction process, becoming molten rock. This molten material can then push to the surface during volcanic activity.
