solifluction
Solifluction is a geological process where water-saturated soil slowly flows down a slope due to gravity. This phenomenon typically occurs in areas with permafrost, where the upper layer of soil thaws during warmer months while the underlying layer remains frozen. The saturated soil becomes heavy and begins to move, creating a gradual, downhill movement.
This process can lead to the formation of distinctive landforms, such as solifluction lobes and terracettes. These features are often seen in tundra regions and can impact vegetation patterns and soil stability. Understanding solifluction is important for studying climate change and its effects on landscapes.
