How do rockslides occur
WebChapter structure. Hillslopes are an almost universal landform, occupying some 90% of the land surface. In hilly and mountainous regions, long-term downslope movement of soil on hillslopes can play a crucial role governing the rate at which landscape evolves through time. Although river incision is often considered to mainly drive landscape ... WebTrue. Solifluction is an important mass wasting process in areas of permafrost. True. A triggering mechanism, such as heavy rains or an earthquake, are necessary for mass wasting to occur. False. Earthflows and slumps generally involve movement of unconsolidated or weakly consolidated soil and regolith. True.
