Term
Abrasion 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, after friction, the moving particles dislodge loose and weak debris from the side of the rock, these particles can be dissolved in the water source |
