Kyushu–Palau Ridge system

Target entity: Kyushu–Palau Ridge system
Context triple: [Philippine Sea Plate, hasTrench, Kyushu–Palau Ridge system]

• A. Izu–Bonin Arc
  The Izu–Bonin Arc is a volcanic island arc in the western Pacific Ocean formed by subduction along the boundary of the Philippine Sea Plate, stretching south from Japan’s Izu Peninsula toward the Mariana Islands.
• B. Japan Trench
  The Japan Trench is a deep oceanic trench off northeastern Japan where the Pacific Plate subducts beneath the Okhotsk Plate, forming part of the Pacific Ring of Fire and generating powerful earthquakes and tsunamis.
• C. Okinawa Plate
  The Okinawa Plate is a minor tectonic plate in the western Pacific region, underlying parts of the East China Sea and associated with active subduction zones and seismic activity near Japan and Taiwan.
• D. Alpha–Mendeleev Ridge complex
  The Alpha–Mendeleev Ridge complex is a large submarine volcanic ridge system in the Arctic Ocean, forming part of the ocean floor topography between the Eurasian and Amerasian basins.
• E. Aleutian Arc
  The Aleutian Arc is a major volcanic island chain and subduction zone stretching from Alaska toward Russia, forming part of the tectonically active northern boundary of the Pacific Ocean.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
