Can Abrasion Occur Underwater?

💡 The Answer

• Yes, solid objects transported in river channels cause abrasion on bed and walls.
• Waves breaking on coastlines transport objects that abrade coastal surfaces.
• Underwater currents can move particles that abrade submarine rock.
• Glaciers also abrade underwater if they terminate in water.
• So abrasion occurs in both subaerial and subaqueous environments.
• The process is similar but medium (water) affects particle movement.
