* Volcanic arcs: Chains of volcanoes that form on the overriding plate, often parallel to the trench. These volcanoes are fed by magma generated from the melting of the subducting plate.
* Ocean trenches: Deep, narrow depressions in the ocean floor that mark the location where the subducting plate bends downward.
* Fold and thrust belts: Series of mountains and valleys that are formed by the compression of the overriding plate.
* Earthquakes: Frequent and often powerful earthquakes occur along the subduction zone as the plates interact.
* Accretionary prisms: Accumulations of sediment and rock scraped off the subducting plate and added to the overriding plate.
Some examples of subduction zones include:
* The Andes Mountains: Formed by the subduction of the Nazca Plate beneath the South American Plate.
* The Japanese Islands: Formed by the subduction of the Pacific Plate beneath the Eurasian Plate.
* The Aleutian Islands: Formed by the subduction of the Pacific Plate beneath the North American Plate.
So, in summary, subduction zones are the defining landforms created at plate boundaries where one oceanic plate descends beneath another.
