Among them are:. They are often triggered by earthquakes and volcanic eruptions. A block slide is a translational slide in which the moving mass consists of a single unit or a few closely related units that move downslope as a relatively coherent mass figure 2c. A lahar is a mudflow that forms from volcanic ash and debris. Slope Failures - a sudden failure of the slope resulting in transport of debris down hill by sliding, rolling, falling, or slumping. On a slope, the force of gravity can be resolved into two components: a component acting perpendicular to the slope, and a component acting parallel to the slope. Combined with joints running perpendicular to the slope as seen in the sandstone body in the illustration abovethe joint pattern results in fractures along which blocks can become loosened to slide down-slope. Heavy rains or earthquakes usually trigger slumps. Water also increases the mass of the soil, this is important because an increase in mass means that there will be an increase in velocity if mass wasting is triggered. Identify different types of movement: —fast movements mudflows, slumping, landslides, avalanches —slow movements solifluction and soil creep.

    Mass movement causes regolith and rock to move down-slope Water can seep into the soil or rock and replace the air in the pore space or fractures.

    Changes in the groundwater system can increase or decrease fluid. Formerly, the term mass wasting referred to a variety of processes by which large and increase the likelihood of mass movement; and flowing ground water.

    The white areas on green hillsides mark scars from numerous mudflows. In expands particles are the dry period the soil will dry out and then contract. This article includes a list of referencesrelated reading or external linksbut its sources remain unclear because it lacks inline citations.

    Movement of soil and regolith that more resembles fluid behavior is called a flow.
