A rotational slump occurs when a slump block, composed of sediment or rock, slides along a concave-upward slip surface with rotation about an axis parallel to the slope. [3] Rotational movement causes the original surface of the block to become less steep, and the top of the slump is rotated backward.
Mass wasting, also known as mass movement, [1] is a general term for the movement of rock or soil down slopes under the force of gravity. It differs from other processes of erosion in that the debris transported by mass wasting is not entrained in a moving medium, such as water, wind, or ice.
Its speed can range from being barely noticeable to rapid movement. The velocity of the flow is dictated by water content: the higher the water content is, the higher the velocity will be. [ 1 ] Because of the dependency on water content for the velocity of the flow, it can take minutes or years for the materials to move down the slope.
Mass wasting or mass movement is the downward and outward movement of rock and sediments on a sloped surface, mainly due to the force of gravity. [ 49 ] [ 50 ] Mass wasting is an important part of the erosional process and is often the first stage in the breakdown and transport of weathered materials in mountainous areas.
Movement of soil by burrowing animals; Slumping and landsliding of the hillslope; These processes generally combine to give the hillslope a profile that looks like a solution to the diffusion equation, where the diffusivity is a parameter that relates to the ease of sediment transport on the particular hillslope. For this reason, the tops of ...
Her performance, and the resulting image — which has come to serve as a symbol for the historic day — was born from a recurring dream that haunted her around the time the protest movement began.
It refers to the gravity-driven failure and subsequent movement downslope of any types of surface movement of soil, rock, or other debris. The term incorporates earth slides, rock falls, flows, and mudslides, amongst other categories of hillslope mass movements. [12] They do not have to be as fluid as a mudflow.
