solifluction
solifluction Physical Geogr. (səʊ-, sɒlɪˈflʌkʃən) Also -fluxion. [f. L. sol-um ground, earth + -i- + fluction, fluxion.] 1. The gradual movement of waterlogged soil or other surface material down a slope, esp. where the subsoil is frozen and acts as a barrier to the percolation of surface water.1906...

Solifluction
Slow periglacial solifluction is classified into four types:
Ice creep
Frost creep
Gelifluction
Plug-like flow
Slow solifluction acts much slower than In contrast, solifluction sheet sediments move more or less uniformly downslope, thus being a less selective form of erosion than solifluction lobes.

Periglaciation
Similarly, solifluction associated with freeze-thaw extends into somewhat lower latitudes than on western coasts. Solifluction lobes – Solifluction lobes are formed when waterlogged soil slips down a slope due to gravity forming U shaped lobes.

Nivation
Weathered particles are moved downslope by creep, solifluction and rill wash.

Interfluve
Formation
These landforms are created by earth flow ("solifluction").

Gelifluction
Gelifluction, very similar to solifluction, is the seasonal freeze-thaw action upon waterlogging topsoils which induces downslope movement.

Diamicton
Although the term is most commonly applied to unsorted glacial deposits (i.e., glacial till), other processes that create diamictons are solifluction,

Mass wasting
Solifluction
Solifluction is a form of creep characteristics of arctic or alpine climates. Solifluction affects the entire slope rather than being confined to channels and can produce terrace-like landforms or stone rivers.

Terracette
Various causes have been suggested to explain their origin including: animal trampling, vegetation and regolith behaviour, soil creep and solifluction

Micranthes hieraciifolia
It grows in meadows, on solifluction soil, and in places with well-developed moss.

Geocarpy
Geocarpy is also linked with solifluction soils, where rapid thawing and freezing of surface soil causes almost continuous movement.

Stratified slope deposit
Pleistocene-aged stratified slope deposits formed from stone-banked solifluction lobes. A major process that forms stratified slope deposits in periglacial areas is solifluction of stone blankets in the form of solifluction lobes and sheets

Periglacial lake
Areas that are too dry for glaciation to occur but that display characteristics of oversteepened slopes, solifluction slumps and cirques indicate the presence Chief actions in these zones include solifluction and frost-shattering processes, the effects of which can be seen in the south of the Bristol Channel.
