Describe the heaving process that results in soil creep
Freezing and thawing of soil water,and wetting and drying of soils or clay minerals, can lead to soilheaving. For example, when soil water freezes, it expands, pushingoverlying soil particles upward relative to the surface of the slope.When that ice thaws, the soil particles move back, but not to theiroriginal positions because the force of gravity pulls downward. Soil creep results fromrepeated cycles of expansion and contraction related to freezingand thawing, or wetting and drying, which cause lifting followedby the downslope movement of soil and rock particles.
