Processes that are driven by the freezing and thawing of ice, which can be a strong enough force to crack rock and move large boulders.
Cold climates (with average annual temperatures of -15 to -1oC and seasonally snow-free ground), or surface features created under those climates.
Environments dominated by ground ice and freeze/thaw processes, as in the tundra.
Said of the processes, conditions, areas, climates, and topographic features at the immediate margins of former and existing glaciers and ice sheets, and influenced by the cold temperature of the ice.
The term periglacial refers to the conditions, processes and landforms associated with cold, nonglacial environments.
refers to areas on the edges of glacial areas. Periglacial conditions in the Pleistocene created landscapes and geological conditions moulded by frost action, the repeated freezing and thawing of material over long periods of time.
The conditions, processes, and landforms associated with cold, nonglacial environments, regardless of proximity to past or present glaciers.
The climatic and geomorphological zone peripheral to the ice sheets and glaciers at high latitudes, and occupying nonglacial environments at high latitudes.
refers to zone or environment surrounding an ice sheet or cap, often characterized by harsh climate.
Landforms created by processes associated with intense freeze-thaw action in an area high latitude areas or near an alpine or continental glacier.
Of, or pertaining to, the outer perimeter of a glacier, particularly to the fringe areas surrounding the great continental glaciers of the geologic ice ages. Thus, "periglacial weathering" is said to have produced certain characteristic land forms.
