Target entity: West Antarctic Rift System
Context triple: [West Antarctica, underlainBy, West Antarctic Rift System]
  • A. West Antarctic Rift System chosen
    The West Antarctic Rift System is a major tectonic rift zone underlying much of West Antarctica, characterized by crustal extension, volcanism, and significant influence on the region’s topography and ice sheet dynamics.
  • B. American-Antarctic Ridge
    The American-Antarctic Ridge is a mid-ocean ridge in the South Atlantic–Southern Ocean region where the American and Antarctic tectonic plates diverge, forming part of the global system of seafloor spreading centers.
  • C. Pacific-Antarctic Ridge
    The Pacific-Antarctic Ridge is a major mid-ocean spreading center in the Southern Ocean where the Pacific and Antarctic tectonic plates diverge, creating new oceanic crust.
  • D. Amundsen Basin
    Amundsen Basin is a deep oceanic basin in the Arctic Ocean, forming part of the complex seafloor topography between Greenland, Svalbard, and the Siberian continental margin.
  • E. South Scotia Ridge
    The South Scotia Ridge is a major submarine mountain chain in the Southern Ocean forming part of the tectonic boundary between the Scotia Plate and the Antarctic Plate.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
