Creeps
Creeps are the slow, steady, downhill flow of loose, weathered Earth materials, especially soils. The movement of a creep is as little as a few centimeters per year, but over time it becomes very noticeable. A way to tell whether a creep is occurring is to observe the positions of structures and objects.
Creeps that usually occurs in regions of permafrost, or permanently frozen soil, is called solifluction. Solifluction is water-logged materials in permafrost regions where water cannot soak through the ground,or in tropic regions when water is saturated. The material moved in solifluction is a mudlike liquid that is produced when water is released from melting permafrost during the warm season. The water saturates the surface layer of soil and is unable to move down. As a result. the surface layer can slide slowly downward.
