Solifluction, which is also known as soil fluction, is a geological term for a type of mass wasting. In solifluction, there exists 2 layers: an impermeable lower layer, and a sedimentary upper layer. When these layers exist on a hill and the top layer becomes saturated with water, the sediment begins to slowly slide down the hill over the lower layer.
More often than not, it occurs in periglacial environments, where a bottom layer of ice begins to melt, resulting in water saturation of the upper layer and the formation of a "flow".
Be careful not to get solifluction mixed with gelifluction though - gelifluction has a permanently frozen bottom layer, while solifluction doesn't.
Solifluction is a type of mass wasting or creep that occurs in regions with permafrost or gelisols. It is characterized by the gradual downhill movement of water-saturated soils over impermeable materials due to freeze-thaw cycles, resulting in the slow flow of the soil. This process is common in Arctic and subarctic regions.

What season does solifluction occur?
Solifluction only occurs during the summer. :)
What primarily operates in areas permafrost?
solifluction
When does solifluction may occur?
Solifluction typically occurs in areas with permafrost or saturated ground that thaw during warmer periods. It is most commonly observed in Arctic and alpine regions. Factors such as freeze-thaw cycles, steep slopes, and presence of water can trigger solifluction movement.
Water-saturated debris over impermeable materials is called?
solifluction
Which process of mass wasting occurs primarily in permafrost regions?
solifluction
Is solifluction an important mass wasting process in areas of permafrost?
true
What kinds of mass wasting processes do you we see?
we have soil creep,solifluction,rock falls,earthflows,mud flows
Why is solifluction only a summertime?
In the summer, the soil thaws to some depth below the surface, but the water is trapped in the thawed soil because the permafrost zone is impermeable. Thus solifluction occurs only in the summer when the surface soil layer is thawed. In the winter the surface soil layer is frozen solid.
Where does solifluction occur?
Solifluction occurs in periglacial environments, such as areas near the edges of glaciers or in cold regions with frozen ground known as permafrost. It is a type of mass wasting where saturated soil flows slowly downhill over frozen ground due to the combination of thawing and freeze-thaw cycles.

What Is the name of the process in which beach sediment moved down is called?
This process is known as longshore drift.
What is the term for when soggy soil slides down frozen ground?
The term for when soggy soil slides down frozen ground is "solifluction." This process is common in regions with permafrost or frozen ground where the active layer thaws and becomes saturated with water, leading to downhill movement of soil and rock.
