Question

The term "patterned ground" refers to the distinct shapes formed in frozen ground due to the expansion and contraction of frost action. These shapes can include circles, polygons, or other patterns composed of soil particles, stones, and small boulders. Gelifluction and solifluction are similar processes that involve the slow movement of soil and debris over time due to the freezing and thawing of the ground, but they do not necessarily result in distinct shapes like patterned ground. Taliks are areas of unfrozen ground that can occur beneath permafrost or other frozen soil layers.
