ice sheet
ice sheet
Noun
pl: ice sheets
This term is a technical geological descriptor used primarily in glaciology and climatology. It describes a specific scale of glaciation that is distinct from an ice cap or a glacier; while a glacier flows in a specific direction, an ice sheet is a continental-scale mass that flows outward from a central point of accumulation.
In academic and scientific discourse, the term carries a neutral, descriptive tone, though in the context of environmental science, it is frequently associated with discussions of melting and sea-level rise.
