Target entity: East Pacific tectonic system
Context triple: [Tehuantepec Ridge, partOf, East Pacific tectonic system]
  • A. Pacific–North American plate boundary system
    The Pacific–North American plate boundary system is a major tectonic boundary zone where the Pacific Plate and North American Plate interact through a complex network of faults and plate motions along western North America.
  • B. North American plate boundary system
    The North American plate boundary system is the complex network of tectonic plate boundaries and associated fault zones that define the interactions and margins of the North American Plate with adjacent plates.
  • C. Tonga-Kermadec subduction system
    The Tonga-Kermadec subduction system is a major convergent plate boundary in the southwest Pacific where the Pacific Plate descends beneath the Indo-Australian Plate, producing one of the world’s deepest ocean trenches and most active seismic and volcanic regions.
  • D. Sunda subduction system
    The Sunda subduction system is a major convergent plate boundary in Southeast Asia where the Indo-Australian Plate is being subducted beneath the Eurasian/Sunda Plate, generating intense seismic and volcanic activity along Indonesia’s island arcs.
  • E. Cocos–Nazca spreading center
    The Cocos–Nazca spreading center is a mid-ocean ridge in the eastern Pacific where tectonic divergence forms and separates the Cocos and Nazca plates.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
