Document Summary
Lesson: mass wasting, landslides (10/6/2016: mass wasting, a downhill movement of masses of bedrock, debris, or soil under the pull of gravity, mass movement, rock fall, rockslide, rock avalanche, debris slide, debris fall. Gravity becomes the main force of stress. Bedrock falls and breaks free of cliffs and bounce down: rock fragments are called, talus. Rapid sliding of a mass of bedrock along and inclined surface. A very rapidly moving turbulent mass of broken up bedrock. A coherent mass of debris moving along a well defended surface. A free falling mass of debris: basic types of movements. Mass moves downhill as a viscous fluid. Slips along a well-defined surface: translational slide, movement parallel to motion, rotational slide (slump, moves along a curved surface. A mass free-falls or bounce down a cliff. The scare on land left by the slide: usually very steep, speeds, rate of movement. Solid bedrock: loose debris, type of movements.
