Drumlins Las morrenas son pas las solas formacions depausadas pels glacièrs. Dins d'airals determinats que dins d'unas ocasions foguèron cobèrts per las calòtas glaciàrias continentalas existís una varietat especiala de païsatge glaciari caracterizat per de còlas lisadas, alargadas e parallèlas sonadas drumlins . Drumlins - these are mounds of glacial material, deposited by the glacier. The exact process of formation is not known. They lie parallel to the direction of the ice movement. They have a smooth elongated shape because of later ice movem 7 Feb 2006 Drumlins may be composed of layers of till (sediment deposited by a glacier), frequently clay-rich, in which the pebbles are oriented subparallel to drumlin elongation and the direction of ice flow, although many drumlins h 18 Mar 2015 When glaciers retreat, they sometimes leave behind an enigmatic landform known as a drumlin field, an area of elongated hills aligned parallel to the flow of ice.

As the ice advanced, it moved rocks, gravel and sand and created Streamlined hills of till aligned parallel to ice flow direction are called drumlins. Although glaciers are made of ice, there is also commonly a significant amount of flowing water due to melting ice. This meltwater can flow on top of, or in channels within and underneath the ice. Drumlins are depositional landforms formed by a glacier.

A drumlin, from the Irish word droimnín ("littlest ridge"), first recorded in 1833, and in the classical sense is an elongated hill in the shape of an inverted spoon or half-buried egg formed by glacial ice acting on underlying unconsolidated till or ground moraine. Drumlins are undoubtedly among the most intensively studied of all glacial landforms and have bee particularly widely used as ice-directional indicators.

In the middle of U-shaped valleys that have been carved by glaciers, we often find small hills between 2 m and 100 m tall. These hills are called drumlins. But how do they form? 2010-11-16 Drumlins are found in groups called drumlin fields or drumlin camps.

Previously this kind of landform could be studied only by focusing on drumlin fields that formed long ago in the Pleistocene, so this study provided a unique opportunity to understand drumlin formation better. Drumlins are large hill-sized oval mounds caused by glaciers dropping their basal debris load as a result of friction between the ice and the underlying geology.
