Abrasion (geology) - Wikipedia
网页Abrasion is a process of weathering that occurs when material being transported wears away at a surface over time, commonly happens in ice and glaciers. The primary process of abrasion is physical weathering. Its the process of friction caused by scuffing, scratching, wearing down, marring, and rubbing away of materials.
Erosion | Description, Causes, Facts, & Types | Britannica
网页2024年9月7日 · Erosion, physical process in which soil, rock, and other surface material are removed from one location and transported to another. Erosion will often occur after rock has been disintegrated or altered through weathering. Weathered rock will be removed from its original site and transported away by a natural agent.
Erosion - Wikipedia
网页Erosion is the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved material from one location on the Earth's crust and then transports it to another location where it is deposited. Erosion is distinct from weathering which involves no …
Erosion - National Geographic Society
网页2024年4月23日 · Erosion is the opposite of deposition, the geological process in which earthen materials are deposited, or built up, on a landform. Most erosion is performed by liquid water, wind, or ice (usually in the form of a glacier). If the wind is dusty, or water or glacial ice is muddy, erosion is taking place.

网页2021年1月1日 · Another method of marine erosion is abrasion, the mechanical wearing and grinding away of rock surfaces by the friction and impact of rock particles. Also called corrasion, this process involves the action of sand, gravel, and large rocks picked up by the waves and driven back and forth against the exposed shore.

Abrasion - SpringerLink
网页Abrasion is the physical process of rubbing, scouring, or scraping whereby particles of rock (usually microscopic) are eroded away by friction. Thornbury (1954, p. 47) indicates that all the four principal agencies of erosion may involve abrasion: (a) running water, (b) waves and currents, (c) wind, and (d) glaciers.

What is coastal erosion? - Internet Geography
网页There are four main processes of coastal erosion. These are corrasion, abrasion, hydraulic action and attrition. Corrasion is when destructive waves pick up beach material (e.g. pebbles) and hurl them at the base of a cliff. Over time this can loosen cliff material forming a wave-cut notch.
