As the glaciers expanded, due to their accumulating weight of snow and ice, they crush and abrade scoured surface rocks and bedrock. The resulting erosional landforms include striations, cirques, glacial horns, arêtes, trim lines, U-shaped valleys, roches moutonnées, overdeepenings and hanging valleys.
- Cirque: Starting location for mountain glaciers
- U-shaped valley: U-shaped valleys are created by mountain glaciers, called fjord when filled with ocean water, creating an inlet
- Arête: spiky high land inbetween 2 glaciers, if the glacier gets through, a Spillway (or Col) is formed
