- Glacial Erosion Landforms
- Corries
- a round hollow in a hill side
- tarn/corrie lake is often formed
- extend backwards
- erosion by ice
- growth= narrow ridge separates 2 encroaching corrie headwalls
- a ridge between 2 corries
- growth= narrow ridge separates 2 encroaching corrie headwalls
- erosion by ice
- a round hollow in a hill side
- Arete
- a ridge between 2 corries
- Pyramidal Peak
- Sharp peak formed where the ridges separating 3 or more corries meet
- U- shaped valley
- Truncated Spurs
- Interlocking Spurs
- ridges of land form in its upper course which jut into the river
- Glaciers cut through interlocking spurs leaving truncated spurs
- Interlocking Spurs
- ribbon lakes
- forms in a hollow where glacier deeply eroded- less resistant rock
- behind a wall of moraine
- large, narrow lake
- glacier retreats-depeens meltwater= lakes
- forms in a hollow where glacier deeply eroded- less resistant rock
- behind a wall of moraine
- forms in a hollow where glacier deeply eroded- less resistant rock
- forms in a hollow where glacier deeply eroded- less resistant rock
- earlier a V-shaped valley
- glacier erodes sides and floorof river valley = deepening, widening, straightening
- ice melts= U-shaped valley
- later rivers = misfit streams
- ribbon lakes
- large, narrow lake
- glacier retreats-depeens meltwater= lakes
- ribbon lakes
- later rivers = misfit streams
- ice melts= U-shaped valley
- glacier erodes sides and floorof river valley = deepening, widening, straightening
- Hanging Valley
- U-shaped valleys ending with a waterfall at the cliff-face
- Truncated Spurs
- Corries
