Till after avalanche, Norway. Till or glacial till is unsorted glacial sediment. Till is derived from the erosion and entrainment of material by the moving ice of a glacier. It is deposited some distance down-ice to form terminal, lateral, medial and ground moraines. Till is classified into primary deposits, laid down directly by glaciers, and ...
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]
The snow-free debris hills around the lagoon are lateral and terminal moraines of a valley glacier in Manang, Nepal.. A moraine is any accumulation of unconsolidated debris (regolith and rock), sometimes referred to as glacial till, that occurs in both currently and formerly glaciated regions, and that has been previously carried along by a glacier or ice sheet.
Till plains are large flat or gently sloping areas of land on which glacial till has been deposited from a melted glacier. In some areas, these depositions can be up to hundreds of feet thick. The morphology of the till plain is generally reflective of the topography of the bedrock below the glacier. Another term for till plain is ground ...
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 rare and very old ...
The Biafo Glacier is the world's third longest glacier outside the polar regions, second only to the 70 km (43 mi) Siachen Glacier, contested between Pakistan and India, and Tajikistan's 77 km (48 mi) long Fedchenko Glacier. Campsites along the Biafo are located off the glacier, adjacent to the lateral moraines and steep mountainsides.
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 or rounded bottom (by contrast, valleys carved by rivers tend to be V-shaped in ...
Writing systems are used to record human language, and may be classified according to certain common features. The usual name of the script is given first; the name of the languages in which the script is written follows (in brackets), particularly in the case where the language name differs from the script name. Other informative or qualifying ...
