Target class: Quaternary megascale glacier Context triple: [Northern Hemisphere ice sheets, instanceOf, Quaternary megascale glacier]
-
A.
glacier
A glacier is a massive, persistent body of dense ice that forms on land from accumulated snowfall and slowly flows under its own weight, reshaping the landscape over time.
-
B.
Pleistocene glaciation
Pleistocene glaciation refers to the series of extensive, repeated ice ages during the Pleistocene epoch when large ice sheets advanced and retreated over vast areas of the Northern Hemisphere, profoundly shaping Earth’s landscapes and climate.
-
C.
continental ice sheet
chosen
A continental ice sheet is a massive, continuous expanse of glacial ice that covers vast land areas, often burying underlying topography and shaping the landscape over long geological timescales.
-
D.
glaciation
Glaciation is the process and period during which large areas of the Earth's surface become covered by glaciers and ice sheets, significantly reshaping landscapes and influencing global climate.
-
E.
glacial fjord system
A glacial fjord system is a coastal landscape formed where glaciers carve deep, steep-sided valleys that are later flooded by the sea, creating interconnected basins, sills, and channels with distinct physical, chemical, and ecological characteristics.
- F. None of above.
Provenance (1 batch)
The batch behind each pipeline step, in order, with when it ran. Timestamps are batch-level — stages were processed in waves, so the object chain (NER → NED1 → NEDg → NED2) reads in order, but predicate / elicitation batches can sit in a different wave.
