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.
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.
Subsequently, What is slumping GCSE geography?
Landslides occur where layers of rock dip towards the sea, and whole blocks of land slips down towards the sea. Slumping occurs in areas with alternating layers of permeable and impermeable rock. Erosion. This is the wearing away of the land by moving agents such as the sea.

What is the difference between slump and creep?
Creeps and slumps are very similar. They are both a form of mass wasting and have the same causes. The difference between a creep and a slump is that a creep moves slowly and gradually while a slump is faster and causes more drastic changes in terrain.
What is slumping also known as?
A slump is sometimes referred to as a rotational slide because a portion or block of the slope ‘slides’ down as it ‘rotates’ around an axis parallel to the slope.
What is slump and creep?
Creeps and slumps are very similar. They are both a form of mass wasting and have the same causes. The difference between a creep and a slump is that a creep moves slowly and gradually while a slump is faster and causes more drastic changes in terrain.
What is slumping answer in one sentence?
When the weathered materials do not move downward but sink “in situ”, this is called slumping. Such rapid mass movements may also occur beccause of earthquakes.
What is slumping in geology?
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 a slump person?
Slump: A period of decline or deterioration, during which a person performs slowly, inefficiently, or ineffectively. Recently, I slipped into a slump. If you’ve been in a slump before, you’ll know how disempowering it feels. It feels like you are stuck and can’t get anything done.
Where do slumps occur?
Slump is common where clay-rich materials are exposed along a steep slope. Such oversteepend slopes naturally occur on the outside of meanders along the Red River. Slump is typically identified as the downward movement of a block of earth material along some curved surface of failure.
Where do earth slumps occur?
Slump is common where clay-rich materials are exposed along a steep slope. Such oversteepend slopes naturally occur on the outside of meanders along the Red River. Slump is typically identified as the downward movement of a block of earth material along some curved surface of failure.
What does slumping mean?
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 causes slumping and creeping?
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. Figure 2. Trees with curved trunks are often signs that the hillside is slowly creeping downhill.
What is a slump landslide?
Block slides and slumps occur where blocks or masses of intact soil or rock move downslope along a failure surface. Block slides have straight failure surfaces, and the motion is analogous to a box (the landslide mass) sliding down a ramp (the failure surface). Slumps, on the other hand, have concave failure surfaces.
What does slumping in a chair mean?
vb intr. 1 to sink or fall heavily and suddenly. 2 to relax ungracefully. 3 (of business activity, etc.)
What does slump mean in concrete?
Slump. Slump is the measure of concrete consistency and fluidity. It shows the flow and overall workability of freshly mixed concrete. Simply put, the higher the slump, the wetter the mix. Four-inch (4”) slump is very common with normal weight concrete and is a good for pumping.
What causes a creep?
The most important process producing creep, aside from direct gravitational influences, is frost heaving: as interstitial water freezes, surface particles are forced up and out perpendicular to the slope; when let down by melting, these particles are drawn directly downward by gravity and are thereby gradually moved …
What causes a slump?
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. … Causes of slumping include earthquake shocks, thorough wetting, freezing and thawing, undercutting, and loading of a slope.
