The video explains the erosive power of glaciers, highlighting processes like plucking and abrasion. Plucking involves glaciers pulling rocks from the ground, creating jagged landscapes. Abrasion smooths surfaces as glaciers drag embedded rocks across the land. Glaciers flow downhill, widening V-shaped valleys into U-shaped ones, demonstrating glacial erosion.
