ABRASION (GEOLOGY)

Glacially abraded rocks in western Norway near Jostedalsbreen glacier.

'Abrasion' is mechanical scraping of a rock surface by friction between rocks and moving particles during their transport in wind, glacier, waves, gravity or running water.
The intensity of abrasion depends on the hardness, concentration, velocity and mass of moving particles.
Abrasion polishes rock faces.

A glacier can "carve" a valley, wearing away rocks and soil through abrasion and plucking up and moving large pieces of rock and debris.
