What does creep mean? Dislocation creep is a deformation mechanism in crystalline materials. Feature creep, more commonly known as scope creep, refers to when you add excessive features to a product that make it too complicated or difficult to use. â Definition, Features 4. Z. Geology Dictionary - Terms Started With Alphabet T. Term : tectonic creep. Most geological changes occur so slowly that we need to look for subtle signs, which give an indication that conditions are changing. Dictionaries. Facebook Twitter Google Email Earthquakes Hazards Data Education Monitoring Research. in geology, the gradual slipping downhill of loose soil or stones. seismograph: 1 n a measuring instrument for detecting and measuring the intensity and direction and duration of movements of the ground (as an earthquake) Type of: measuring device , measuring instrument , measuring system instrument that shows the extent or ⦠â (of a plant) grow along the ground or other surface by means of extending stems or branches. Solifluction is the name for the slow downhill flow of soil in arctic regions. This can include gravel sliding... See full answer below. noun. Creep generally moves unconsolidated materials, such as soil or regolith. Slump moves materials as a large block along a curved surface (figure 7). o Dissolution creep: pressure solution. It commonly involves a shear plane on which a back-tilting of the top of the slumped mass occurs. It more or less uniformly affects the whole thickness of the soil rather than collecting in certain areas. A stage of the wind erosion process in which grains of sand move each other along the surface. Also called creepers. in order to avoid being heard or noticed. Creep is the tendency of a solid material to move or change shape slightly as a result of stress that continues for some time. See creep.. slow downslope movement of particles that occurs on every slope covered with loose, weathered material. a sensation as of something crawling over the skin, caused by uneasiness or loathing (prec. In materials science, creep (sometimes called cold flow) is the tendency of a solid material to move slowly or deform permanently under the influence of persistent mechanical stresses. ⢠Occurs at low differential stress and T conditions. Creep is more severe in materials that are subjected to heat for long periods and generally increases as they near their melting point. Damp soil moves very slowly down the slope as the weight of water pushes it forwards. During creep, damage accumulates in the form of internal cavities. Creep is the slowest form of mass movement, measured in millimeters or centimenters per year and occurring on virtually all slopes. As the stress continues, the extension of the metal caused by creep eventually leads to failure. an introduction on how landslides can be mitigated and managed as a hazard. ing, creeps 1. (uncountable) The gradual expansion or proliferation of something beyond its original goals or boundaries, considered negatively. Any additional features that you introduce in to your product add to the complexity of your design. The difference between these two concepts is subtle but important. used to describe any movement that involves a steady, gradual change in shape. Creep is a type of wind erosion which includes the movement of heavy soil particles from one place to another due to the action of wind. In materials science, creep (sometimes called cold flow) is the tendency of a solid material to move slowly or deform permanently under the influence of persistent mechanical stresses. A cabochon is a stone or other material that has been shaped and polished rather than faceted. creep leads to the development of convex upward slope segments; solifluction, slumps, and flows commonly result in concave upward profiles at their heads and convex toes of colluvium ... Geology: Slope composition and structure controls the detachability of slope material by a particular process . The aspen trees in the above photo show that the soil in which they are growing has been moving downslope in a mass wasting process known as creep. In geology, aseismic creep is measurable surface displacement along a fault in the absence of notable earthquakes. Shuguang Song, Yi Cao, in Encyclopedia of Geology (Second Edition), 2021. Creep definition, to move slowly with the body close to the ground, as a reptile or an insect, or a person on hands and knees. 2. Soil creep is a process operating at the granular scale. What is Creep. Definition : The almost constant movement of certain fault blocks that allows strain energy to be released without major earthquakes. Talus creep involves the very slow downslope movement of the layers of the talus, which typically occupies the foot of the escarpment, being at its thickest between Kalvi and Paite (Fig. a very slow mass movement that goes on for years or even centuries. Dictionary of Chemical Terms. It can occur as a result of long-term exposure to high levels of stress that are still below the yield strength of the material. See more. Dislocation creep involves the movement of dislocations through the crystal lattice of the material, in contrast to diffusion creep, in which diffusion (of vacancies) is the dominant creep mechanism. How to Stop Earth Creep From a Hillside. ⢠Relies on the dissolution of the mineral along boundaries of impinging grains, the diffusion of dissolved material along grain boundaries or microfractures, and the reprecipitation of ⦠It happens on gentle slopes and is noticeable from the wavy surface it produces. Slow, more or less continuous movement occurring on faults due to ongoing tectonic deformation. by "the"). Ductile deformation mechanisms. noun Geology. fault creep. noun In coal-mining, the apparent rising of the floor, or under-clay, of the mine between the pillars, or where the roof is not fully supported, caused by the pressure of the superincumbent strata. Creep (sediment grains): slow, sliding movement of small pebbles along desert surfaces due to impacts of wind-borne sand grains. Landslide causes are listed in the following table, and include geological factors, The landslide causes are the reasons that a landslide occurred in that location and at that time. Search Mechanical Creep. The stretching response evoked by tension applied to skin for minutes to hours after scalp reduction in hair replacement, which is attributed to realignment of collagen fibers. Creep is indicated by curved tree trunks, bent fences or retaining walls, tilted poles or fences, and small soil ripples or ridges. Slump and Creep. creep / krÄp / ⢠v. (past and past part. definition 3: (informal, pl.) In turn, this can diminish the usability of ⦠X. Y. noun plural A sensation as of something crawling over one; a sensation as of shivering. ... (geology) The imperceptible downslope movement of surface rock. 3. Fault Creep Fault Creep: Fault creep means slow ground displacement of a strike-slip fault or dip-slip fault, that usually occurs without accompanying earthquakes. Questions or comments? creep of soil on even slopes; often accelerated by spring freeze-and-thaw or general periglacial conditions.Compare creep (def. Stones that are cut en cabochon will typically have a front side that is domed and polished, while the back side is flat to allow it to be mounted in jewelry. 1. move slowly and carefully, esp. Creep is the imperceptibly slow, steady, downward movement of slope-forming soil or rock. It occurs slowly and is measured in millimeters or centimeters per year. The movement of something that creeps (like worms or snails) 2. It is usually possible to identify one or more landslide causes and one landslide trigger. Creep, known also as cold flow, is the permanent deformation that increases with time under constant load or stress. Soil creep definition is - slow down-slope movement of earth materials under the influence of gravitation. See creep, v. i., 6. To move with the body close to the ground, as on hands and knees. crept / krept /) [intr.] 0 Less dramatic types of downslope movement move earth materials slowly down a hillside. It rarely extends to more than a few meters in depth. 0. Definition. creep (countable and uncountable, plural creeps) 1. Find out information about surface creep. The plane is slightly concave upward and outward and separates the slump block from unslumped material of the same character.
