This process is commonly demonstrated by noting the bending of trees growing on ground under which it is occurring.
This process can be accelerated by a special form of temperature and compositional fatigue known as frost heaving. One model suitable for this process is sometimes given the name Stokes and other times coincidentally shares the name of this phenomenon; that model is the set of solutions to Navier-Stokes equations with Reynolds number much less than one. This longest-timescale member of the family of granular processes on regolith has characteristic speeds overlapping those of the slurry process of solifluction. This process is commonly demonstrated by noting the bending of trees growing on ground under which it is occurring. For 10 points, name this largest and slowest form of mass wasting, the simple downhill flow of soil due to gravity.
