Abrasion - Rocks and boulders in the base of the glacier acting like a giant file scratching and scraping the rocks below, Plucking - Melt water in the glacier freezes onto rocks, and as the ice moves forward it plucks or pulls out large pieces along the rock joints, Freeze-thaw weathering - On the valley sides, repeated freezing and thawing of water in cracks breaks rocks apart. These rocks then falls down the valley side as scree, Bulldozing - At the snout of the glacier, the ice pushes material of all shapes and sizes as it moves slowly forward., Rotational slip - This occurs when the ice moves in a circular motion. This process can help to erode hollows in the landscape, and deepen hollows into bowl shapes.,
