Erosion Processes
Erosional processes along coastlines include: (1) the direct effects of hydraulic action, wedging, and cavitation by waves; (2) abrasion (corrasion), using sand, gravel, and larger rock fragments as tools; (3) attrition of the rock particles themselves during this abrasive action; (4) salt weathering or fretting; (5) erosion by organisms (bioerosion); and (6) …

Abrasion vs Attrition
Abrasion vs Attrition. Abrasion refers to the mechanical scraping or grinding of rocks or sediments caused by the impact of other rocks, sediment, or abrasive particles such as sand. Attrition is the process of wearing down of rocks and sediments by collision and friction between particles, forming sedimentary rocks.
