Question

Quizplus · Accepted Answer

Solifluction is a type of mass wasting that occurs in areas with permafrost. Permafrost is a layer of soil that remains frozen year-round and is common in high latitudes and high altitudes. In solifluction, the top layer of soil thaws during the summer, becoming saturated with water, and flows downhill over the frozen layer of soil beneath it. This process can cause slow but steady downhill movement of the soil and vegetation. Rockslides, slumps, and debris flows are not directly related to permafrost.
