In this case, a massive body of rock is very slowly sliding down a steep slope along a plane of weakness that is caused by the foliation in the rock. The foliation is approximately parallel to the slope. Webba. The angle of repose is about 30 degrees. b. The angle of repose is the minimum angle at which a slope is stable. c. The angle of repose is used to refer to bedrock or unconsolidated sediment. d. The angle of repose varies depending on the grain size and shape of the sediment. flooding lumby bc

WebbA sediment flow is a mixture of rock, and/or regolith with some water or air. They can be broken into two types depending on the amount of water present.
