Erosion: Pressure release
when overlying materials are removed by erosion, or other processes, which causes underlying rocks to expand and fracture.
Transportation : Bulldozing
Rocks and debris found in front of the glacier are pushed along by the moving ice.
Transportation : Rotational Slip
Semicircular motion of ice as it moves downslope along a concave face. It can help to make hollows in the landscape, deepening them into bowl shapes.
Erosion: Striations
Long scratches created where moraine scraped against resistant rock
Erosion: Cirque/Corrie/Cwm
Steep sided, half-open hollow formed at the head of a glacier
Erosion: Plucking
Basal ice freezes in rock surface cracks. As the main body of the glacial ice moves material around the ice in the cracks is pulled and plucked out.
Erosion: Tarn/Lochan/Corrie Lake
Lake formed by meltwater and/or precipitation in a cwm
Erosion: Horn/Pyramidal Peak
three-sided, pointed mountain peak
Formed when 3+ back-to-back corrie glaciers carve away at the top of a mountain
Erosion: Truncated Spurs
Formed where a glacier cuts off interlocking spurs formed by a river
Erosion: Nunataks
Rocky island surrounded by glacial ice
Erosion: Hanging Valley
Formed where the U-shaped valleys of tributary glaciers meet the main U-shaped valley
Erosion: ArĂŞte
knife-edge, steep-sided ridges
Formed when two corries cut back into the mountainsideÂ
Erosion: Fjord
U-shaped valley flooded by rising sea levels
Erosion: Ribbon/Finger Lake
Lake formed in the depression left by overdeepening by the base of a glacier
Erosion: Glacial Trough
U-shaped valley formed where a glacier has passed
Erosion: Roche Mountonée
Rocks, one side smoothed by abrasion and the other steep and rough from plucking
Deposition: Till
Boulder clay, unconsolidated, variety of particle sizes
Deposition: Erratics
Boulders deposited from the glacier with foreign geology
Deposition: Moraine
Any rock carried by the glacier, lateral, medial, ground, terminal
Deposition: Drumlins
Smooth, elongated mounds of till, steep on one side and gentle on the other, often found in groups
Deposition: Kettle Holes/Lakes
Form from detached blocks of ice, melt and leave behind a depression which often fills with water
Deposition: Glacial Flour
Suspended load of rock dust in water
Deposition: Outwash
Flat areas of meltwater below the snout of glaciers, made from till, eskers, erratics, drumlins all found on this plain
Deposition: Eskers
Long, narrow ridges of sand+gravel, formed by deposits of sub-glacial meltwater streams
