Phrase: Snowball Earth glaciations | Statement: [Precambrian Supereon, includesEvent, Snowball Earth glaciations]

Target entity: Snowball Earth glaciations
Context triple: [Precambrian Supereon, includesEvent, Snowball Earth glaciations]

• A. 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.
• B. Eocene–Oligocene climate transition
  The Eocene–Oligocene climate transition was a major global cooling event around 34 million years ago that marked the shift from a greenhouse to an icehouse Earth, including the formation of large Antarctic ice sheets.
• C. Milankovitch cycles
  Milankovitch cycles are long-term variations in Earth’s orbit and axial tilt that drive natural climate fluctuations, including the timing of ice ages.
• D. 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.
• E. Northern Hemisphere ice sheets
  Northern Hemisphere ice sheets are vast continental glaciers that repeatedly expanded and retreated over North America and Eurasia, profoundly shaping global climate, sea levels, and landscapes during the Quaternary.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Generate a one-sentence description of the target entity. 
You are given a context triple in the form (subject, predicate, object), where the object is the target entity. 
# Instructions
Use the triple to infer relevant information about the entity. Describe the entity based on what is most defining, well-known. 
Avoid repeating the information from the triple, unless really essential.
# Response Format
Return only the sentence: "Description: [one-sentence description of the target entity]"

Entity: Snowball Earth glaciations
Triple: [Precambrian Supereon, includesEvent, Snowball Earth glaciations]

Snowball Earth glaciations were extreme global-scale ice ages in the Precambrian when ice sheets may have covered most or all of Earth’s surface for millions of years.
