Step 1: Abrasion. As the glacier moves, rocks and sediment embedded in its base and sides scrape against the underlying bedrock. This acts like sandpaper, grinding down the rock surface and polishing it. The embedded debris can range from fine sand to large boulders, causing significant wear. Step 2: Plucking (or Quarrying). The moving ice can freeze onto the bedrock surface. As the glacier continues to move, it can exert a powerful force that pulls chunks of rock away from the bedrock. This happens particularly in areas where the bedrock has cracks or joints, making it easier for the ice to detach pieces. Send me the next one 📸
