Earthflows are just one type of mass movement that can occur on a hill slope. As the slope becomes wet, the earthflow may start as a creep downslope due to the clay or silt having less friction. As the material is increasingly more saturated, the slope will fail, which depends on slope stability. Eustasio Gloggler Pundit. What is permafrost and what can result from disturbing it? What is permafrost, and what can result from disturbing it?
Permafrost is permanently frozen ground. If the thermal balance of permafrost is disturbed , ice within the permafrost may melt, causing the ground to slide, slump, or subside.
Goyo Loscertales Pundit. How do slides and flows differ? Flows are a mixture of water, rock and sediment. They move very quickly. Large flows can bury entire villages. A slide happens when a section of soil or rock suddenly gives way and moves down a slope. Nunzio Pages Pundit. What are some clues that a proposed home site may be susceptible to landslide activity? Landslide warning signs. Springs, seeps or saturated ground in areas that are not usually wet. New cracks or unusual bulges in the ground, street or sidewalks.
Soil moving away from foundations, or the tilting or cracking of concrete floors and foundations. Sunken or down-dropped road beds. Aurelija Cotado Teacher. How does a rockfall differ from a rockslide? In a rockfall , rocks or rock fragments fall freely through the air. In a rockslide , a block that includes segments of bedrock moves suddenly along a flat, inclined surface. Ernesta Klotz Supporter.
How is soil defined? Soil can be defined as the organic and inorganic materials on the surface of the earth that provide the medium for plant growth.
Soil develops slowly over time and is composed of many different materials. Kadia Benayad Supporter. What is the percolation rate of water in soil? Percolation is the property of absorption of water by soil.
If we pour a bottle of water on the floor and another bottle of water in the soil , the water on the floor will flow down but water in the soil will be absorbed. The percolation rate is the amount of water absorbed by any soil at any given time.
Isusko Charoshnikov Supporter. As shown in Figure However, it is not actually known what triggered this event as the weather was dry and warm during the preceding weeks, and there was no significant earthquake in the region.
The Hope Slide Figure The slide at Mt. Meager west of Lillooet was also a rock avalanche, and rivals the Hope Slide as the largest slope failure in Canada during historical times Figure Creep , which normally only affects the upper several centimetres of loose material, is typically a type of very slow flow, but in some cases, sliding may take place. Creep can be facilitated by freezing and thawing because, as shown in Figure The same effect can be produced by frequent wetting and drying of the soil.
In cold environments, solifluction is a more intense form of freeze-thaw-triggered creep. Creep is most noticeable on moderate-to-steep slopes where trees, fence posts, or grave markers are consistently leaning in a downhill direction Figure Slump is a type of slide movement as a mass that takes place within thick unconsolidated deposits typically thicker than 10 m.
Slumps involve movement along one or more curved failure surfaces, with downward motion near the top and outward motion toward the bottom Figure They are typically caused by an excess of water within these materials on a steep slope. An example of a slump in the Lethbridge area of Alberta is shown in Figure This feature has likely been active for many decades, and moves a little more whenever there are heavy spring rains and significant snowmelt runoff.
The toe of the slump is failing because it has been eroded by the small stream at the bottom. As you saw in Exercise This can happen during rapid spring snowmelt or heavy rains, and is also relatively common during volcanic eruptions because of the rapid melting of snow and ice. The definition of landslides is when land slides. Also, mudslides are also a total science word. It is when mud slides.
A creep is the extremely slow movement of material downslope and a landslide is the sudden and rapid movement of a large amount of material downslope.
Creep - increase in deformation while load is cst Relaxation - decrease in load while deformation is cst. A landslide is the most destuctive type of mass movement and a mudslide is the rapid movement of a mixure of water, rock, and soil. There is no difference. The term mudslide is simply a misnomer for mudflow. Everything I hated the movie it's just really creep and stupid. Lava is hot molten rock that is erupted onto Earth's surface by a volcano. A lahar is a mudflow formed by a mixture of water and volcanic ash.
This difference in height in mm. The heavy rains caused a mudflow. The mudflow came down the hill and hit the village. Mass movement is a fast process in the formation of landslides. Mass movement is a slow process in the formation of creep. From what I heard, the electron mudflow traveled about two miles.
A mudflow is a mixture of sediment and water that moves down hill in a fluid manner. Both landslides and avalanches are can be caused by heavy rain or snow. An avalanche is great volumes of mass sliding down a sloped area, a mudslide or mudflow also are great volumes of mass sliding down a sloped area. Log in. The Difference Between. Study now.
