Which type of mass movement occurs along a curved surface?

Which type of mass movement occurs along a curved surface?

Slump
Slump – involves movement along a curved surface, the upper part moving downward while the lower part moves outward. Slide – A descending rock mass remaining relatively coherent, moving along one or more well defined surfaces.

What types of mass movement does gravity move loose material down a slope?

A general term used to describe all relatively rapid forms of mass wasting. Mass wasting: The spontaneous movement of material down a slope in response to gravity.

Which type of mass movement refers to a block of material moving down a flat inclined surface?

A mass movement that involves the sudden movement of a block of material along a flat, inclined surface is called a. slide. rockfall.

What is the downward movement of a block of material along a curved surface?

A slump is the downward movement of a block of material along a curved surface.

How do rocks and soil move down the slope?

mass movement, also called Mass Wasting, bulk movements of soil and rock debris down slopes in response to the pull of gravity, or the rapid or gradual sinking of the Earth’s ground surface in a predominantly vertical direction.

What occurs when the mass of material in a landslide moves along a curved surface?

Slump and Creep Slump moves materials as a large block along a curved surface (figure 7). Slumps often happen when a slope is undercut, with no support for the overlying materials, or when too much weight is added to an unstable slope. Slump material moves as a whole unit, leaving behind a crescent shaped scar.

When soil gradually move down a slope?

Creep, in geology, slow downslope movement of particles that occurs on every slope covered with loose, weathered material. Even soil covered with close-knit sod creeps downslope, as indicated by slow but persistent tilting of trees, poles, gravestones, and other objects set into the ground on hillsides.

How does slope affect deposition?

Water flowing over Earth’s surface or underground causes erosion and deposition. Water flowing over a steeper slope moves faster and causes more erosion. When water slows down, it starts depositing sediment, starting with the largest particles first. Runoff erodes the land after a heavy rain.

What is the down slope movement of material under the influence of gravity quizlet?

What is the slow down slope movement of water-saturated surface sediment? The down slope movement of rock, regolith, and soil under the direct influence of gravity. Its role is the Geologic process that often follows weathering and, combined with running water, produces stream valleys.

What are mass movements on a slope called?

Mass movements that move blocks of materials and unconsolidated materials down a curved surface creating scarps on a slope are known as SLUMP. 3. When large rocks become dislodged and drop down a steep slope, the mass movement is called a FALL. 4. CREEPS are very gradual mass movements in which the whole slope moves downhill slowly. 5.

What is the term for a mass movement?

A mass movement in which a cohesive block of earth or rock slips downhill relatively quickly in one piece along a zone of weakness is called a SLIDE. 2. Mass movements that move blocks of materials and unconsolidated materials down a curved surface creating scarps on a slope are known as SLUMP. 3.

When do materials move along a curved surface?

Slump moves materials as a large block along a curved surface (figure 7). Slumps often happen when a slope is undercut, with no support for the overlying materials, or when too much weight is added to an unstable slope. Figure 7. Slump material moves as a whole unit, leaving behind a crescent shaped scar.

When does unconsolidated material move downslope it is called a flow?

When unconsolidated material moves downslope as a viscous fluid it is called a FLOW. You will label the five types of mass wasting in terms of the materials they carry.
