answer choices soil creep landslide slump mudslide Question 3 30 seconds Q. That means, air, water or ice do not carry debris with them from place to place but . Steep slopes can be covered or sprayed with concrete covered or with a wire mesh to prevent rock falls. Mass movement is the downslope movement of material (rock and soil) under the force of gravity. to grain contact and reducing the angle of repose, thus triggering a mass movement. Mass movements affect the following elements of the environment: (1) the topography of the earth's surface, particularly the morphologies of mountain and valley systems, both on the continents and on the ocean floors; (2) the character/quality of rivers and streams and groundwater flow; (3) the forests that cover much . This is because the water gets Mass movement is also known as mass wasting. Flows Flows refer to the movement of the soil, dust, rock particles and bigger pabbles resembling the fluid behavior. The emigration of Syrians during war, the flow of water in the Gulf Stream, and the expansion of cell phone reception around the planet are all examples of movement. one another and the open space will be reduced. Mass movement is the movement of surface material caused by gravity. Trees bind the soil from moving and can also intercept and slow down mass movements eg earthflows. unstable all of the time and the process is continuous. A sediment flow is a mixture of rock, mass movements can be extremely hazardous and result in extensive loss of life and 1 of 16 Mass Movement Jul. The gradient of the slope is one of the most important factors that affects mass movement. "This page last updated on " + A faint rumbling sound that increases in volume is noticeable as the landslide nears. Mass movements (also called mass-wasting) is the down-slope movement of Regolith (loose uncemented mixture of soil and rock particles that covers the Earth's surface) by the force of gravity without the aid of a transporting medium such as water, ice, or wind. Landslides may create lakes when the rocky material dams a stream. Telephone polls being tilted on a hill are an example of this type of mass movement. Water can reduce the friction along a sliding surface. 3 types can occur - (1) Submarine slumps Coherent blocks break and slip, similar to slumps on land. var m = date.getMonth() + 1; (from USGS Landslide Hazards -. In what ways does water added to a slope affect its stability? Regions divide the world into manageable units for geographic study. If the material becomes saturated with water, vibrations could cause liquifaction to occur, just like often happens during earthquakes. between the grains and eliminates grain to grain frictional contact. groundwater system can increase or decrease fluid pressure in rock and also trigger Water can seep into the soil or rock and replace the air in the pore space or fractures.

Ice, although it is solid, does have the
