what is mass movement?

Answer 1

Mass movement is the down slope movement of earth materials under the influence of gravity. The detachment and movement of earth materials occurs if the stress imposed is greater than the strength of the material to hold it in place. Shear strength is a measure if the resistance of earth materials to be moved. The interlocking of soil particles increases the ability of material to stay in place. Plant roots also help bind soil particles together. Shear stress is primarily a function of the force exerted by the weight of the material under the influence of gravity acting in the down slope direction. The slope of the surface determines the amount of stress that occurs on earth materials. Water destabilizes hill slopes by creating pressure in the pore spaces of earth materials. Water infiltrating into slope materials saturates the soil particles at depth by filling the pore spaces between. The weight of water lying above creates water pressure that drives soil particles apart. This lessens the friction between them and enables them to slip past one another. Material is mobilized when the shear stress imposed on a surface exceeds the shear strength. The movement, especially in the case of slides and slumps, is along a failure plane. The failure plane may be a well-defined layer of clay or rock upon which sets the destabilized surface material. Humans induce mass movement when subjecting a slope to a load that exceeds its ability to resist movement. People building houses on scenic hill slopes often find their homes threatened by a landslide. Undercutting of hillsides during road construction commonly creates unstable slopes making them prone to failure.

Answer 2

Mass wasting, also known as mass movement or slope movement, is the geomorphic process by which soil, regolith, and rock move down-slope under the force of gravity. Types of mass wasting include creep, slides, flows, topples, and falls, each with their own characteristic features, and take place over timescales from seconds to years. Mass wasting occurs on terrestrial and submarine slopes, and has been observed on Earth and Mars.

Answer 3

Your question is a little vague. Could you be thinking of mass transport? Physics have worked with the concept of accelerating a mass down a long track to sufficient speed to launch it into orbit.

Also, the transporter beam in Star Trek could be considered a mass transfer system since it takes people from one place to somewhere else. (Presumably, it turns them into energy which it beams to the destination where they are turned back into mass.)
