What is a flow of rock or sediment along a curved surface often down an eroded cliff?

What is a flow of rock or sediment along a curved surface often down an eroded cliff?

rock undergoes weathering + is changed and moved. Mass movement is caused by ice? No: GRAVITY. Creep is a flow of rock or sediment along a curved surface, often down and eroded cliff? No: SLUMP.

What is the movement of rock or sediment?

erosion
Sediment moves from one place to another through the process of erosion. Erosion is the removal and transportation of rock or soil. Erosion can move sediment through water, ice, or wind. Water can wash sediment, such as gravel or pebbles, down from a creek, into a river, and eventually to that river’s delta.

What is the movement of sediment and rock particles called?

Erosion is the process by which soil and rock particles are worn away and moved elsewhere by gravity, or by a moving transport agent – wind, water or ice.

What is a landslide along a curved surface called?

Rock Slump. cohesive blocks of soft earth material slide on a curved surface; also called a rotational landslide. Complex Slide. a combination of two or more types of sliding, flowage and occasionally falls; forms where on type of landslide changes into another as it moves downslope.

What is a flow landslide?

Flows are landslides that involve the movement of material down a slope in the form of a fluid. Flows often leave behind a distinctive, upside-down funnel shaped deposit where the landslide material has stopped moving.

How are sediment flows classified?

Three constitutive conditions prevail during sedimentation that define the flow character of a sediment gravity flow in its final stage: (I) the flow is either laminar or turbulent; (II) the flow behavior is either plastic (cohesive) or fluidal (cohesionless); (III) its concentration is either low or high.

What is sediment process?

Sedimentation is the process of allowing particles in suspension in water to settle out of the suspension under the effect of gravity. The particles that settle out from the suspension become sediment, and in water treatment is known as sludge.

What kind of pressure does a sedimentary rock have?

The pressure, known as lithostatic pressure, “squeezes” the sediments from all sides into a smaller volume. Lithostatic pressure packs the sediment grains closer together and reduces the porosity – space between the sediment grains.

How are sediments transported on the surface of a bed?

As soon as flow attains a force sufficient to erode particles, sediments are transported in a set of structures on the surface of beds called bedforms . There is a predictable sequence of bedforms that depends on velocity, grains size and depth of flow. Temperature and viscosity (clay content) can also alter bedforms.

How are sediments and sedimentary rocks related to each other?

Reflect on the rock cycle for an indication of the relationships between the rocks that erode to become sediments and sedimentary rocks. For sediment to become sedimentary rock, it usually undergoes burial, compaction, and cementation.

How does lithification affect the formation of sedimentary rocks?

Lithification—Sediments to Sedimentary rocks. Lithostatic pressure packs the sediment grains closer together and reduces the porosity – space between the sediment grains. Some chemical sedimentary rocks are rock as soon as the sediments have been deposited by crystallization of minerals from substances dissolved in water, at the earth’s surface.
