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 ...
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 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 ...
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 ...
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]
A proglacial lake is an impoundment of water prevented from flowing by a glacier, glacial till dam or behind a glacial feature such as an end moraine. [4] Proglacial lakes are usually the byproduct of glacial meltwater. The sediment contained in a proglacial lake is a useful geochronological tool that records patterns of change in a glaciated ...
Soil erosion is the denudation or wearing away of the upper layer of soil. It is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice (glaciers), snow, air (wind), plants, and animals (including humans). In accordance with these agents, erosion is sometimes divided into water ...
