Target entity: Sturtian glaciation
Context triple: [Neoproterozoic Era, includesEvent, Sturtian glaciation]
  • A. Huronian glaciation
    The Huronian glaciation was one of Earth's earliest and longest ice ages, occurring over 2.4 billion years ago and likely linked to the Great Oxidation Event and major climatic shifts.
  • B. Rhyacian Period
    The Rhyacian Period is a geologic time interval in the early Proterozoic characterized by significant crustal growth, widespread metamorphism, and some of the earliest known large-scale glaciations.
  • C. Last Glacial Maximum
    The Last Glacial Maximum was the most recent period in Earth’s history when ice sheets reached their greatest extent, dramatically lowering sea levels and reshaping global climates and ecosystems.
  • D. Cenozoic glaciations
    Cenozoic glaciations are a series of major ice age cycles during the Cenozoic Era that saw extensive growth and retreat of continental ice sheets, profoundly shaping Earth’s climate and landscapes.
  • E. Younger Dryas cold event
    The Younger Dryas cold event was a brief, abrupt return to near-glacial conditions about 12,900–11,700 years ago that interrupted the general warming trend at the end of the last Ice Age.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
