ETYM Latin abrasio, from abradere. Related to Abrade.
1. An abraded area where the skin is torn or worn off; SYN. scratch, scrape, excoriation.
2. Erosion by friction; SYN. attrition, corrasion, detrition.

In medicine, another term for a graze or other minor lesion where the skin surface is worn away by friction.
In earth science, the effect of corrasion, a type of erosion in which rock fragments scrape and grind away a surface. The rock fragments may be carried by rivers, wind, ice, or the sea. Striations, or grooves, on rock surfaces are common abrasions, caused by the scratching of rock debris embedded in glacier ice.
ETYM Latin erosio. Related to Erode.
Wearing away of the Earth's surface, caused by the breakdown and transportation of particles of rock or soil (by contrast, weathering does not involve transportation). Agents of erosion include the sea, rivers, glaciers, and wind.
Water, consisting of sea waves and currents, rivers, and rain; ice, in the form of glaciers; and wind, hurling sand fragments against exposed rocks and moving dunes along, are the most potent forces of erosion. People also contribute to erosion by bad farming practices and the cutting down of forests, which can lead to the formation of dust bowls.
Agents of erosion include the sea, rivers, glaciers, and wind.
There are several processes of erosion including hydraulic action, corrasion, attrition, and solution.
1. Condition in which the earth's surface is worn away by the action of water and wind.
2. The mechanical process of wearing or grinding something down (as by particles washing over it); SYN. eroding, eating away, wearing, wearing away.
