Photograph taken 21 March 2010 in Norwich, Vermont. Frost heaving (or a frost heave) is an upwards swelling of soil during freezing conditions caused by an increasing presence of ice as it grows towards the surface, upwards from the depth in the soil where freezing temperatures have penetrated into the soil (the freezing front or freezing boundary).
Ice jacking is a continuous process that occurs during the winter in areas near lakes. The process starts when the ice begins to crack. When water then fills in those gaps, the process repeats and continues until there is a wall of ice surrounding the lake's shoreline, sometimes reaching up to three feet.
A process called frost heaving is responsible for these features. Solifluction lobes – Solifluction lobes are formed when waterlogged soil slips down a slope due to gravity, forming U-shaped lobes. Blockfields or Felsenmeer – Blockfields are areas covered by large angular blocks, traditionally believed to have been created by freeze-thaw ...
The maximum frost depth observed in the contiguous United States ranges from 0 to 8 feet (2.4 m). [1] Below that depth, the temperature varies, but is always above 0 °C (32 °F). Alternatively, in Arctic and Antarctic locations the freezing depth is so deep that it becomes year-round permafrost , and the term " thaw depth " is used instead.
Nivation is the set of geomorphic processes associated with snow patches.The primary processes are mass wasting and the freeze and thaw cycle, [1] in which fallen snow gets compacted into firn or névé.
The patterned ground below Mugi Hill on Mount Kenya lies in an area of seasonal frost. [1] A pingo and polygonal ground near Tuktoyaktuk , Northwest Territories, Canada Patterned ground is the distinct and often symmetrical natural pattern of geometric shapes formed by the deformation of ground material in periglacial regions.
Frost creep [A] Gelifluction; Plug-like flow; Slow solifluction acts much slower than some geochemical fluxes or than other erosion processes. [1] The relatively low rates at which solifluction operates contrast with its occurrence over wide mountain areas and periglaciated lowlands.
