The grinding away of bedrock by fragments of rock which may be incorporated in ice (glacial abrasion), water (marine abrasion, fluvial abrasion), or wind (aeolian abrasion). In fluvial environments, the main agent of abrasion is the bed load. The mass of solid material removed varies with the size, density, and velocity of the particles, and the density of the vector bearing these particles. Ice ceases to be an effective agent for abrasion when the weight of the ice is thick enough to bring about plastic flow. Abrasion is an alternative term for corrasion. See striations.

A surface discontinuity caused by roughening or scratching.

graze

An acute injury resulting from shearing forces between the skin surface and another surface (e.g. road surface, football pitch, mat, or skin). The skin surface is broken, but there is no complete tear throughout its depth. Abrasions are common in sport and are usually regarded by athletes as being trivial. Consequently, they are often inadequately treated and can become infected with disease-producing organisms. Treatment includes thorough and immediate cleansing of the abrasion with soap and water, thorough irrigation, followed by the application of a sterile dressing. A useful mnemonic of the treatment is SID: S = Soak, soap, scrub; I = Irrigate, irrigate, irrigate; D = Dressing.

IN BRIEF: That which is rubbed off.
