Glacial landform. Glacial landforms are landforms created by the action of glaciers. Most of today's glacial landforms were created by the movement of large ice sheets during the Quaternary glaciations. Some areas, like Fennoscandia and the southern Andes, have extensive occurrences of glacial landforms; other areas, such as the Sahara, display ...
Glacier. Glacier of the Geikie Plateau in Greenland. The Taschachferner in the Ötztal Alps in Austria. The mountain to the left is the Wildspitze (3.768 m), second highest in Austria. With 7,253 known glaciers, Pakistan contains more glacial ice than any other country on earth outside the polar regions. [1]
U-shaped valley with lake in Myklebustdalen, Nordfjord, Sogn og Fjordane, Norway. U-shaped valleys, also called trough valleys or glacial troughs, are formed by the process of glaciation. They are characteristic of mountain glaciation in particular. [1] They have a characteristic U shape in cross-section, with steep, straight sides and a flat ...
The shape is modified by coastal processes. An esker, eskar, eschar, or os, sometimes called an asar, osar, or serpent kame, [1][2] is a long, winding ridge of stratified sand and gravel, examples of which occur in glaciated and formerly glaciated regions of Europe and North America. Eskers are frequently several kilometres long and, because of ...
Roche moutonnée near Myot Hill, Scotland 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 (i.e. pieces cracked off) on the "lee" (downstream) side.
Kame. A kame, or knob, is a glacial landform, an irregularly shaped hill or mound composed of sand, gravel and till that accumulates in a depression on a retreating glacier, and is then deposited on the land surface with further melting of the glacier. Kames are often associated with kettles, and this is referred to as kame and kettle or knob ...
a glacial meltwater valley, the Urstromtal, through which meltwaters from the glacier flowed away. The term "glacial series" is restricted to landforms created by glaciers and classified by geomorphological rules, as opposed to the glacial sediments and sedimentary rocks associated with glaciers and classified by their geological features. A ...
Kame delta. A kame delta (or ice-contact delta, morainic delta[1]) is a glacial landform formed by a stream of melt water flowing through or around a glacier and depositing material, known as kame (stratified sequence of sediments) deposits. Upon entering a proglacial lake at the end (terminus) of a glacier, the river/stream deposit these ...
