- Creep is the imperceptibly slow, steady, downward movement of slope-forming soil or rock. Movement is caused by shear stress sufficient to produce permanent deformation, but too small to produce shear failure.

What does creep mean in physics?
What is continuous soil creep?
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.

Mar 1, 2018 · As articulated by Varnes (1978), “creep is simply deformation that continues under constant stress”. The crucial driving factors (gravity, viscous/frictional forces) work permanently and the resulting process is known as continuous soil creep (synonymous with rheological, viscous, mass, deep-seated).

Dec 26, 2021 · 10.4: Creep. The expressive term creep is used for all slow downslope movements of regolith under the pull of gravity that are so slow as to be imperceptible except to observations with long duration (days to weeks in the case of solifluction; years to decades to centuries in the case of slower creep).
Feb 7, 2023 · Creep is the gradual downslope displacement of regolith due to gravity, commonly with the aid of ground disturbance. (Note the distinction from the broader definition used in mechanics, in which creep refers more generally to permanent deformation of a material in response to stress).

A periglacial landscape is characterised by permanently frozen ground or permafrost and is defined as: ‘An area where soil and rock has not risen above 0°C for at least 2 consecutive years'. Permafrost is not controlled by soil moisture and ice does not need to be present.
If a load is suddenly applied to such a material and then kept constant, the resulting deformation is not achieved immediately. Rather, the solid gradually deforms and attains its steady-state deformation only after a significant period of time. This behaviour is called creep.
