The most common mass-wasting types are falls, rotational and translational slides, flows, and creep .
What are the 4 types of mass movement?
- Rockfall. Bits of rock fall off the cliff face, usually due to freeze-thaw weathering.
- Mudflow. Saturated soil (soil filled with water) flows down a slope.
- Landslide. Large blocks of rock slide downhill.
- Rotational slip. Saturated soil slumps down a curved surface.
What are the types of mass wasting?
| Failure Type Type of Material | Creep or solifluction Soil or other overburden; in some cases, mixed with ice | Slump Thick deposits (m to 10s of m) of unconsolidated sediment | Mudflow Loose sediment with a significant component of silt and clay | Debris flow Sand, gravel, and larger fragments |

What are the five types of mass wasting?
Types of mass wasting include creep, slides, flows, topples, and falls , each with its own characteristic features, and taking place over timescales from seconds to hundreds of years.
What are the 4 factors that influence mass wasting?
Mass wasting is influenced by slope, material strength, water content, and amount of vegetation . Mass wasting can be triggered by storms, earthquakes, eruptions, and human activity. Fall, slide, flow, and creep are the main categories of mass wasting mechanisms.
What are the four spheres of landslide?
Below are a few ways that landslides affect and are effected by the lithosphere, atmosphere, hydrosphere, and biosphere : Lithosphere- Landslides directly change the surface shape of the lithosphere, they are also sometimes caused by the movements of the lithosphere.
What are the six types of mass movement?
Types of Mass Movement: Creep; Fall, Slip, Flow; Solifluction ; Rock Glaciers; Slumping (Earthflow); Mudflow (lahar); Debris Flow, Debris Slide, Debris Avalanche; Rockslide; Rockfall; Debris Fall.
What are the different types of mass movements and how are they described?
The types of mass movements caused by the above factors include: the abrupt movement and free fall of loosened blocks of solid rock, known as rockfalls ; several types of almost imperceptible downslope movement of surficial soil particles and rock debris, collectively called creep; the subsurface creep of rock material, ...
Which of the following types of mass wasting is the fastest?
A rock fall are the fastest of all landslide types and occurs when a rock falls through the air until it comes to rest on the ground—not too complicated.
What are the different types of mass movement quizlet?
- rockfalls.
- slides.
- slumps.
- flows.
- creep.
What is meant by mass wasting and its types?
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 are types of weathering?
There are three types of weathering, physical, chemical and biological .
What is the difference between slump and creep?
Slump moves materials as a large block along a curved surface (figure 1). 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. ... Creep is the imperceptibly slow, steady, downward movement of slope-forming soil or rock.
What are causes of mass wasting?
The causes of mass wasting include an increased slope steepness, increased water, decreased vegetation and earthquakes . One of the types of mass wasting that is an example of the slope failing is a slump. This is the sliding of coherent rock material along a curved surface.
How is mass wasting different from other forms of erosion?
Erosion is the physical removal and transportation of weathered material by water, wind, ice, or gravity. Mass wasting is the transfer or movement of rock or soil down slope primarily by gravity .
What is the type of mass movement of fall?
Types of mass movement
A fall or topple happens when rocks and other sediments fall through the air and land at the bottom of a slope . Flows are a mixture of water, rock and sediment. They move very quickly. ... Creep is a very slow mass movement that goes on for years or even centuries.
