Target entity: Aegean back-arc extension
Context triple: [Hellenic subduction system, drives, Aegean back-arc extension]
  • A. Hellenic subduction system
    The Hellenic subduction system is a major convergent plate boundary in the eastern Mediterranean where the African Plate is being subducted beneath the Aegean microplate, creating deep-sea trenches, intense seismicity, and active volcanism.
  • B. Andean back-arc basins
    Andean back-arc basins are sedimentary basins that formed behind the Andean volcanic arc due to tectonic extension and subsidence related to subduction along the western margin of South America.
  • C. Ryukyu back-arc basin
    The Ryukyu back-arc basin is a seafloor spreading region behind the Ryukyu island arc, formed by the subduction of the Philippine Sea Plate beneath the Eurasian Plate and characterized by active tectonism and volcanism.
  • D. Aegean Sea Plate
    The Aegean Sea Plate is a small tectonic plate in the eastern Mediterranean responsible for the complex seismic and volcanic activity around the Aegean Sea region.
  • E. East Pacific tectonic system
    The East Pacific tectonic system is a major geological region in the eastern Pacific Ocean characterized by active seafloor spreading, transform faults, and subduction zones that shape the surrounding oceanic plates and continental margins.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
