Q. What are landslides mudflows slump and creep caused by?
The major forms of mass movement are slump, creep, landslides, rockfalls, and mudflows. They are similar in that they are caused by gravity and are helped by water. Slump, landslides, rockfalls, and mudflows are fast while creep is gradual. Mudflows and slump are caused mostly by water.
Q. Which type of mass movement is the most destructive creep erosion landslide slump?
landslides, mudslides, slump, and creep. The most destructive kind of mass movement is a landslide, which occurs when rock and soil slide quickly down a steep slope. Such mass movement is common where road builders have cut highways through hills or mountains.
Q. How does mass wasting occur?
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.
Q. What is the single most important weathering agent?
Weathering and erosion, along with the gravity-driven effect called mass wasting, are the fundamental processes by which rock is broken down and removed, collectively called denudation. The most important agent in both weathering and erosion is water, in both its liquid and solid states.
Q. What factors led to the massive rockslide at Gros Ventre Wyoming?
A combination of three factors caused the rock slide: 1) heavy rains and rapidly melting snow saturated the Tensleep Sandstone causing the underlying shale of the Amsden Formation to lose its shear strength, 2) the Gros Ventre River cut through the sandstone creating an oversteepened slope, and 3) soil on top of the …
Q. What factors increase the risks of landslides?
Landslides can be initiated in slopes already on the verge of movement by rainfall, snowmelt, changes in water level, stream erosion, changes in ground water, earthquakes, volcanic activity, disturbance by human activities, or any combination of these factors.
Q. What is the difference between a debris flow and an earth flow?
A mudflow is a rapid, downslope movement of a dense mixture of weathered rock and water through within the valley. And a debris flow is the stream like flow of dense, muddy water heavily laden with sediments of various sizes.
Q. How fast do Debris flows move?
35 miles
Q. What is called debris?
Debris (UK: /ˈdɛbriː, ˈdeɪbriː/, US: /dəˈbriː/) is rubble, wreckage, ruins, litter and discarded garbage/refuse/trash, scattered remains of something destroyed, discarded, or as in geology, large rock fragments left by a melting glacier etc. Depending on context, debris can refer to a number of different things.
Q. What is debris control?
What is a debris control structure: As the name implies it is a structure that collects and controls debris during flood events. There are 4 typical debris control structures.
Q. What does ancient debris look like?
The texture of the ancient debris is supposed to look like pressed metal plates. Ancient debris yields the most experience of any item when smelted.
