What Causes the Movement of Glaciers That Leads to Abrasion?

💡 The Answer

• Glacier movement is caused by force, friction, vibration, and internal deformation of ice.
• Force from gravity pulls the ice downhill.
• Friction at the base influences sliding.
• Vibration may result from fracturing or flow.
• Internal deformation allows ice to flow like a viscous fluid.
• Sliding over rocks and sediments at the base is the main mechanism for abrasion.
