Roche moutonnée in Murmansk, Russia In glaciology , a roche moutonnée (or sheepback ) is a rock formation created by the passing of a glacier . The passage of glacier 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.

As a glacier moves, hills are generally sheared off and rounded by the moving ice. A characteristic shape produced by both continental ice sheets and mountain glaciers is the roche moutonnée, which is often produced when a bedrock hill is overridden by moving ice.

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

especially joints, on the formation of roches moutonnees and different glacial abrasion forms on roches moutonnees were studied in the south-west archipelago of Finland. The size and form of roches moutonnees are closely connected with the frequency and state of joints in the bedrock. The fewer and smaller the joints are, the larger Roche moutonnées are formed when an outcropping of resistant rock comes into the path of the glacier. This resistant rock is not eroded as easily and so the glacier must move around the rock by ‘creep and regelation’. ‘Creep and regelation’ is an enhancement of basal slip due to obstacles on the bedrock floor.

What kind of information does a roche moutonnée reveal? the direction a glacier was moving By increasing the albedo of the Earth, global ice sheets produce conditions that are ________ to their further advance, thus providing an example of ________ feedback.
