When the rate of weathering and mass movement exceeds the rate of cliff foot erosion a scree slope is formed -> Over time this apron of material extends up the cliff face protecting it from subaerial processes -> This leads to a reduction in the effectiveness of weathering and mass movement. In the United States, coasts can be a reference to culture as much as physical geography. The delivery of sediment to the delta results in some land building and helps to maintain the elevation of the delta surface at or slightly above the elevation of sea level. File previews. . Share : In a systems approach, change in the outputs can be redirected back at the inputs. Often, this means that the consequences of the change are ironically more severe. social science, engineering, and other sciences, as well as courses for interdisciplinary programs.
