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 ...
Delta, River – Silt deposition landform at the mouth of a river; Desert pavement – Type of desert earth surface; Diatreme – Volcanic pipe associated with a gaseous explosion; Dike – Sheet of rock that is formed in a fracture of a pre-existing rock body; Dirt cone – Depositional glacial feature of ice or snow with an insulating layer ...
A cirque (French:; from the Latin word circus) is an amphitheatre-like valley formed by glacial erosion. Alternative names for this landform are corrie (from Scottish Gaelic: coire, meaning a pot or cauldron) [1] and cwm (Welsh for 'valley'; pronounced). A cirque may also be a similarly shaped landform arising from fluvial erosion.
Fluvioglacial landforms or glaciofluvial landforms [a] are those that result from the associated erosion and deposition of sediments caused by glacial meltwater. Glaciers contain suspended sediment loads, much of which is initially picked up from the underlying landmass.
A watering hole is a natural depression where water collects and animals come to drink. Karst closed depression with permanent lake Stymfalia, Peloponnese, Greece. Seasonal abundant precipitation drained by 3 sinkholes. In geology, a depression is a landform sunken or depressed below the surrounding area. Depressions form by various mechanisms.
Arêtes can also form when two glacial cirques erode headwards towards one another, although frequently this results in a saddle-shaped pass, called a col. [2] The edge is then sharpened by freeze-thaw weathering, and the slope on either side of the arête steepened through mass wasting events and the erosion of exposed, unstable rock. [3]
Example of a periglacial landscape with both pingos and polygon wedge ice near Tuktoyaktuk, Northwest Territories, Canada. Periglaciation (adjective: "periglacial", referring to places at the edges of glacial areas) describes geomorphic processes that result from seasonal thawing and freezing, very often in areas of permafrost.
Franz Josef Glacier in New Zealand Features of a glacial landscape. Glacier morphology, or the form a glacier takes, is influenced by temperature, precipitation, topography, and other factors. [1] The goal of glacial morphology is to gain a better understanding of glaciated landscapes and the way they are shaped. [2]
