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.
A smoothly polished surface caused by frictional movement between rocks along the two sides of a fault. This surface is normally striated in the direction of movement. slump A form of mass wasting that occurs when a coherent mass of loosely consolidated materials or rock layers moves a short distance down a slope. snowball Earth
Gully – Landform created by running water and/or mass movement eroding sharply into soil; Hill – Landform that extends above the surrounding terrain; Hillock, also known as Knoll – Small hill; Mesa – Elevated area of land with a flat top and sides, usually much wider than buttes; Mountain pass – Route through a mountain range or over ...
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.
At the time, the civil rights movement of the early ’60s had given birth to the Black Power movement of the late ’60s, and Black Americans were still mourning the 1968 assassination of Martin ...
Movement is driven by shear stress, which is generated by the mass of the block acting under gravity down the slope. Resistance to movement is the result of the normal load. When the slope fills with water, the fluid pressure provides the block with buoyancy, reducing the resistance to movement.
