How Does Glacier Movement Cause Abrasion?

💡 The Answer

• Glacier movement causes abrasion through force, friction, vibration, and internal deformation of ice.
• The glacier slides over rocks and sediments at its base.
• Embedded rocks in ice act like sandpaper.
• Continuous downhill movement scratches and wears bedrock.
• This process is called glacial abrasion.
• It leaves characteristic striations on bedrock surfaces.
