What is mass movement quizlet?
Mass movement is the movement of earth materials called regoilth down a slope under the influence of gravity. … Water and gravity cause the soil to move slowly downhill. This movement is shown on the features of the surface.
What is the difference between mass movement and erosion?
Erosion is the dislodging of sediments that initiates their movement. Particles may then be moved away by sediment transport agents such as wind water glaciers etc. Mass movement refers to earth materials moving downslope under the influence of gravity as in rockslides mudflows slumps etc.

What is weathering and mass movement?
Weathering is the physical disintegration or chemical alteration of rocks at or near the Earth‟s surface. … Mass wasting is the transfer or movement of rock or soil down slope primarily by gravity.
Is slumping mass movement?
A slump is a form of mass wasting that occurs when a coherent mass of loosely consolidated materials or a rock layer moves a short distance down a slope. Movement is characterized by sliding along a concave-upward or planar surface. … Translational slumps occur when a detached landmass moves along a planar surface.

What causes mass movement of large intestine?
Instead general contractions called mass action contractions occur one to three times per day in the large intestine propelling the chyme (now feces) toward the rectum. Mass movements often tend to be triggered by meals as the presence of chyme in the stomach and duodenum prompts them (gastrocolic reflex).
What are the effects of mass movement?
