What happen in rocks during mass wasting flow?
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 movement and their causes in geography?
Mass movement is the downhill movement of sediment that moves because of gravity. There are four different types of mass movement: Rockfall. Bits of rock fall off the cliff face, usually due to freeze-thaw weathering.
What is mass movement in geology?
Mass movements are part of a continuum of erosional processes between weathering and stream transport. Mass movement causes regolith and rock to move down-slope where sooner or later the loose particles will be picked up by another transporting agent and eventually moved to a site of deposition such as an ocean basin or
How does gravity affect the movement of mountains?
Gravity causes sections of cliffs and hills to move down slope. These are called mass movements. Mass movements can be very dangerous because they can happen very quickly and involve entire hillsides. Sometimes a mass movement will dam a river.
What is the role of water in causing mass movement?
Much importance is attached to the role of water – both surface and subsurface, in causing mass movement. Water may act directly to reduce the shearing strength of a rock or soil mass in a number of ways. It may also play an indirect role in promoting the instability conditions for land masses.
What causes sections of cliffs and hills to move down?
Gravity causes sections of cliffs and hills to move down slope. These are called mass movements. The relationship between speed and moisture content in the different types of mass movements. FAST. SLOW. DRY. WET.
