Which factors influence the mass movement of particles?

Such factors include: weathering or erosional debris cover on slopes, which is usually liable to mass movement; the character and structure of rocks, such as resistant permeable beds prone to sliding because of underlying impermeable rocks; the removal of the vegetation cover, which increases the slope’s susceptibility …

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.

Which factor influences the mass movement of particles quizlet?

causes of Mass Movements: Gravity: the most important factor in causing mass movements. Water: adds weight to the slopes and reduces friction between the soil particles. Undercutting of a slope: by natural processes, such as streams.

Which factor most likely facilitates mass movement after heavy rains in a dry region quizlet?

Which factor most likely facilitates mass movement after heavy rains in a dry region? Sediments are carried from a hilltop to the ground at the bottom of the hill on a windy day.

What causes mass movement quizlet?

Gravity causes mass movement.

Where do all mass movements occur?

Mass movement, often called mass wasting, is the downslope movement of a mass of surface materials, such as soil, rock or mud. This mass movement typically occurs along hillsides and mountains due to the influence of gravity and can happen very slowly or very quickly.

Which kind of mass movement would most likely occur after heavy rain?

slump
The intermittent movement (slip) of a mass of earth or rock along a curved plane is a slump. A slump is most likely to occur after a heavy rain, on a steep slope with deep, clay-rich soils.

Which factor most likely facilitates mass movement?

causes of Mass Movements: Gravity: the most important factor in causing mass movements. Water: adds weight to the slopes and reduces friction between the soil particles.

Which factor influences the mass movement of particles erosion and deposition?

Gravity can cause erosion and deposition. Gravity makes water and ice move. It also causes rock, soil, snow, or other material to move downhill in a process called mass movement. Particles in a steep sand pile move downhill.

Which phrase best describes the mass movement of particles quizlet?

soil mixed with water sliding off a cliff, rocks and debris rolling down a steep slope, loosely connected rock and debris traveling down a steep hill. Which phrase best describes the mass movement of particles? sediment flowing down a slope. Which process works with erosion to break down rock?

What type of mass movement is slide?

c) Slides: A slide is the downslope movement of a soil or rock mass occurring dominantly on the surface of rupture or relatively thin zones of intense shear strain.

What is mass movement What are the types of mass movement?

The most common mass-wasting types are falls, rotational and translational slides, flows, and creep. Falls are abrupt rock movements that detach from steep slopes or cliffs. Rocks separate along existing natural breaks such as fractures or bedding planes. Movement occurs as free-falling, bouncing, and rolling.

Which of the following best describes a mass wasting event referred to as a flow?

Creep. Which of the following best describes a mass wasting event referred to as a flow? material moving as a viscous fluid. Only $35.99/year.

What are the four classes of mass movements?

Terms in this set (4)
  • Landslides. -most destructive -rock and soil slide quickly down steep slopes -can be caused by earthquakes.
  • Mudflows. -rapid downhill movement of mixture of water, rock and soil -can occur after heavy rains in normally dry area -can be caused by earthquakes.
  • Slump. …
  • creep.

What type of mass movement has materials that move in a single large mass or block?

Less dramatic types of downslope movement move earth materials slowly down a hillside. Slump moves materials as a large block along a curved surface (figure 7). Slumps often happen when a slope is undercut, with no support for the overlying materials, or when too much weight is added to an unstable slope.

Which of the following best describes mass movement mass wasting?

Which of the following best describes “mass wasting”? … Mass wasting involves soil and sediment, whereas erosion does not. Mass wasting does not require gravity to force rocks downslope, whereas erosion does. Mass wasting is strongly influenced by water and wind, whereas erosion is not.

Which of the following describes mass wasting?

Mass wasting is the movement of rock and soil down slope under the influence of gravity. Rock falls, slumps, and debris flows are all examples of mass wasting. Often lubricated by rainfall or agitated by seismic activity, these events may occur very rapidly and move as a flow.

What is mass wasting quizlet?

mass wasting. any gravity-driven downslope movement of rock or soil. landslide. sudden downslope movement of earth materials (falling, slumping, sliding, and flowing)
