Target entity: East Antarctic Ice Sheet
Context triple: [Transantarctic Mountains, formsBoundaryOf, East Antarctic Ice Sheet]
  • A. Antarctic Ice Sheet
    The Antarctic Ice Sheet is the vast, continent-spanning mass of glacial ice covering Antarctica, holding the majority of Earth’s freshwater and playing a critical role in global sea-level and climate regulation.
  • B. Nansen Ice Sheet
    The Nansen Ice Sheet is a coastal ice shelf in Antarctica bordering the western Ross Sea, known for its role in regional glaciology and climate studies.
  • C. West Antarctica
    West Antarctica is the portion of the Antarctic continent lying mostly west of the Transantarctic Mountains, known for its marine-based ice sheet that is particularly vulnerable to climate change and potential sea-level rise.
  • D. Ross Ice Shelf
    The Ross Ice Shelf is the world’s largest ice shelf, a vast floating extension of the Antarctic ice sheet that plays a key role in buttressing inland glaciers and influencing global sea-level stability.
  • E. Amery Ice Shelf
    The Amery Ice Shelf is one of Antarctica’s largest ice shelves, a massive floating extension of the East Antarctic Ice Sheet that drains inland glaciers into the Southern Ocean.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
