What Is Slumping GCSE Geography?

How does slumping occur geography?

A slump is a form of mass wasting that occurs when a coherent mass of loosely consolidated materials or a rock layer moves a short distance down a slope.

Movement is characterized by sliding along a concave-upward or planar surface.

Translational slumps occur when a detached landmass moves along a planar surface..

What does rockfall mean?

Rockfall is a natural mass-wasting process that involves the dislodging and rapid downslope movement of individual rocks and rock masses. The widespread combination of steep slopes capped by well-jointed bedrock makes rockfall among the most common slope-failure types in Utah.

Is a rockfall a landslide?

A landslide is the movement of a mass of rock, debris, or earth (soil) down a slope. A rockfall is the action of boulders, rocks or slabs of rock falling or toppling.

What is a swash wave?

When a wave breaks, water is washed up the beach. This is called the swash . Then the water runs back down the beach, which is called the backwash . With a constructive wave, the swash is stronger than the backwash. With a destructive wave, the backwash is stronger than the swash.

What does erosion mean in geography?

Erosion is the geological process in which earthen materials are worn away and transported by natural forces such as wind or water. A similar process, weathering, breaks down or dissolves rock, but does not involve movement.

How fast is soil creep?

4.2 Soil creep The highest rates were recorded for temperate climates predominantly affecting soil movement in the surface soils down to the first 25 cm with rates of about 0.5–2 mm yr−1 for the temperate maritime zone and generally higher rates for the temperate continental zone of about 2–10 mm yr−1.

What are the two types of waves geography?

There are two different types of wave – constructive and destructive. They can affect the coastline in different ways. When a wave reaches the shore, the water that rushes up the beach is known as the swash . The water that flows back towards the sea is known as the backwash .

What is soil creep in geography?

Soil creep is a very slow movement, occurring on very gentle slopes because of the way soil particles repeatedly expand and contract in wet and dry periods. When wet, soil particles increase in size and weight, and expand at right angles. … As a result, the soil slowly moves down slope.

What is a rockfall in geography?

“A rockfall is a fragment of rock (a block) detached by sliding, toppling, or falling, that falls along a vertical or sub-vertical cliff, proceeds down slope by bouncing and flying along ballistic trajectories or by rolling on talus or debris slopes.”

How does Cliff slumping occur?

Clay Cliffs: clay is a soft, impermeable rock which soaks up water to become saturated. When this happens the clay becomes unstable and begins to slump. … Cliff Collapse: steep cliffs made of hard, resistant rock, fall down when there is a loss of supporting rock underneath caused by wave attack.

What is slumping in geography?

Slump, in geology, downward intermittent movement of rock debris, usually the consequence of removal of buttressing earth at the foot of a slope of unconsolidated material. It commonly involves a shear plane on which a back-tilting of the top of the slumped mass occurs.

What is the difference between slumping and sliding?

Sliding allows the materials to fall downward in an inclined plane, whereas slumping allows the materials to fall downwcard along a curved plane. Explanation: Sliding and slumping are two of the distinct mass wasting processes, where the loose and unconsolidated materials falls downward under the influence of gravity.

How can rockfall be prevented?

Avoiding Rockfalls And Rock Avalanches Avoidance techniques include building tunnels, realigning or rerouting roads, and elevating structures above the point of danger. While these approaches are the most protective solution, they bear the highest cost to install, along with ongoing maintenance costs.

What causes a rockslide?

A rockslide is a type of landslide caused by rock failure in which part of the bedding plane of failure passes through compacted rock and material collapses en masse and not in individual blocks. … The rocks tumble downhill, loosening other rocks on their way and smashing everything in their path.

What are the 5 types of mass movement?

Types of Mass Movement: Creep; Fall, Slip, Flow; Solifluction; Rock Glaciers; Slumping (Earthflow); Mudflow (lahar); Debris Flow, Debris Slide, Debris Avalanche; Rockslide; Rockfall; Debris Fall.

What is the meaning of slumping?

1a : to fall or sink suddenly. b : to drop or slide down suddenly : collapse. 2 : to assume a drooping posture or carriage : slouch. 3 : to go into a slump sales slumped.

What is a wave geography GCSE?

Waves are formed when the wind blows across the surface of the sea. The friction between the wind and the water pushes the water up creating waves. … The distance it has had to travel across open water to reach the coastline. The wind speed.

What does rotational slip refer to?

rotational slip (rotational slump) Variety of landslide characterized by movement along a concave-up failure surface. The upper unit of the slump is typically tilted back, and surface water may be retained in the depressed zone.

What does swash mean?

noun (1) Definition of swash (Entry 2 of 4) 1 : swagger. 2 : a narrow channel of water lying within a sandbank or between a sandbank and the shore. 3 : a dashing of water against or on something especially : the rush of water up a beach from a breaking wave.

How are corries formed in geography?

Corries form in hollows where snow can accumulate. The snow compacts into ice and this accumulates over many years to compact and grow into a corrie/cirque glacier. This then moves down hill because of gravity and the mass of the ice.
