Glacial erosion can also create a roche moutonnee, which is a mass of rocks carved by a passing glacier. The rock formation has a smooth, rounded side caused by abrasion and a steep, ragged side In glaciology, a roche moutonnée (or sheepback) is a rock formation created by the passing of a glacier. The passage of glacial ice over underlying bedrock often results in asymmetric erosional forms as a result of abrasion on the "stoss" (upstream) side of the rock and plucking on the "lee" (downstream) side.

2020-08-12 · Formation of a roche moutonnée as a result of stress differences over the bedrock surface. High normal stress (pressure) on the stoss face results in bedrock abrasion, whereas lower normal stresses (pressure) on the lee face often allow a cavity to form, which promotes quarrying of bedrock along lines of existing weakness (e.g. bedrock joints).

Like a roche moutonnee, it is formed from a section of rock that was more resistant than its surroundings. On the lee side of the resistant rock, the bed rock was protected from the erosional power of the glacier.

roche moutonnée(glaciated rock knob, stoss-and-lee topography) A mound-like land-form of glacial erosion, consisting of a smoothed, streamlined, up-glacier surface and a broken, shattered, lee flank, which probably results from a combination of abrasion, frost-shattering, and the plucking out of blocks by the glacier, although crushing has been suggested as a contributory mechanism.

The passage of glacial ice over underlying bedrock often results in asymmetric erosional forms as a result of abrasion on the "stoss" side of the rock and plucking on the "lee" side. These erosional features are seen on scales of less than a metre to several hundred metres.–326 Formation of a roche moutonnée as a result of stress differences over the bedrock surface. High normal stress (pressure) on the stoss face results in bedrock abrasion, whereas lower normal stresses (pressure) on the lee face often allow a cavity to form, which promotes quarrying of bedrock along lines of existing weakness (e.g. bedrock joints).
