Question

Quizplus · Accepted Answer

Soil creep is a slow and continuous movement of soil particles downhill, usually caused by the expansion and contraction of soil due to freeze-thaw cycles or wetting and drying. The movement is not sudden or catastrophic like a debris avalanche or soil slide, and can be observed through tilted trees, fence posts, or retaining walls. Rockfall and slump are not related to the movement of surface soil.
