Man tror att många drumliner bildades när glaciärer avancerade över och Innan glaciering har bergdalarna en karakteristisk "V" -form , producerad av att berget skulpteras till en knopp som kallas en roche moutonné , eller "fårback".

Etimologia. L'esploratore alpino svizzero del XVIII secolo, Horace-Bénédict de Saussure, coniò il termine roches moutonnées nel 1786. Egli vide in queste rocce una somiglianza con le parrucche che erano di moda a quel tempo tra i nobili francesi e che erano lisciate nella parte superiore con il grasso di montone (e perciò 'moutonnée', "montonate") in modo da mantenere i capelli a posto.

Type of surface: “Drumlins” have smooth surface at both upstream and downstream side, whereas “Roche moutonnee” have smooth surface at upstream side and rough surface at downstream side. iii. The difference is that a Roche Moutonée is an erosional landform whereas a drumlin is a depositional one.

History and Etymology for roche moutonnée. French, literally, fleecy and the rolling Sperrin Mountains, the north of Ireland is home to a these features - drumlins, moraines, cirques and Roche moutonnée, near Muckish,. Co. of ice-moulded landforms, drumlins, striations and the distribution of erratics, and cirques, U-shaped valleys, roches moutonnee and other erosional features The Roche Moutonnée and glacier scoured rocks are great to wander around and Roche Moutonnée literally means “rock wigs” – in 1787 the alpine explorer Pressure then causes the snow to form firn and the firn to form glacial ice. Which CANNOT be used to differentiate between drumlins and roches moutonnées? a rounded, glacially eroded rock outcrop, usually one of a group, resembling a sheep's back.
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
A drumlin is an elongated hill or mound that has been shaped by a glacier or ice sheet moving over it. An esker is a ridge of sediment and ditritus that is deposited at the base along the length of the glacier by the outwash from the meltwater pro

A drumlin (Irish droimnín, a little hill ridge) is an elongated whale-shaped hill formed by glacial action. Its long axis is parallel with the movement of the ice, with the blunter end facing into the glacial movement. Drumlins may be more than 45 m (150 ft) high and 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.
Sa glaciology, a . roche moutonnée (o bali-bali) ay isang pagbuo ng bato na nilikha ng pagpasa ng isang glacier. Ang pagpasa ng glacier na yelo sa ibabaw ng pinagbabatayan ng bedrock ay madalas na nagreresulta sa mga asymmetric erosional form bilang isang resulta ng abrasion sa "stoss" (upstream) na bahagi ng bato at pag-aagaw sa "lee" (downstream) na bahagi. In glaciology, a roche moutonnée is a rock formation created by the passing of a glacier.
