abrasion
Sign in to saveprocess of wearing down or wearing away of rocks by the hard particles carried by rivers, glaciers, wind and waves
AI overview
Abrasion is the process where rocks get worn down and worn away by hard particles that are carried along by rivers, glaciers, wind, and waves. It matters because it's a natural force that shapes landscapes over time, breaking down mountains and rocky surfaces into smaller pieces and eventually sand and sediment.

Glacially abraded rocks in western Norway near Jostedalsbreen generation
Abrasion is a process of weathering that occurs when material being transported wears away at a surface over time, commonly occurring with 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. The intensity of abrasion depends on the hardness, concentration, velocity and mass of the moving particles. Abrasion generally occurs in four ways: glaciation slowly grinds rocks picked up by ice against rock surfaces; solid objects transported in river channels make abrasive surface contact with the bed and walls; objects transported in waves breaking on coastlines; and by wind transporting sand or small stones against surface rocks. Abrasion is the natural scratching of bedrock by a continuous movement of snow or glacier downhill. This is caused by a force, friction, vibration, or internal deformation of the ice, and by sliding over the rocks and sediments at the base (that also causes an avalanche) that causes the glacier to move.
