Document Summary

He assumed an ideal case of accumulated talus which is not subjected to weathering and has the same volume as parent rock: the scree provides protection to the base of the rock face from weathering. The talus continues to grow and finally, it completely buries the free face (fig). The retreating face above leaves behind protrusion under the scree: the surface of the scree which accumulates at a constant angle is termed as the constant slope (wood, 1942), beneath the scree will lie buried the convex slope. While this is an ideal case but in nature, such a process would be highly complex as there are various factors that affect the evolution of slopes. In nature, the volume of the scree will never be the same as the parent rock rather the volume would be more than parent rock because of the presence of interstitial space.
