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 ...
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. The concave ...
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 process called frost heaving is responsible for these features. Solifluction lobes – Solifluction lobes are formed when waterlogged soil slips down a slope due to gravity, forming U-shaped lobes. Blockfields or Felsenmeer – Blockfields are areas covered by large angular blocks, traditionally believed to have been created by freeze-thaw ...
Glaciers, typically forming in drainages on the sides of a mountain, develop bowl-shaped basins called cirques (sometimes called ‘corries’ - from Scottish Gaelic coire [kʰəɾə] (a bowl) - or cwm s). Cirque glaciers have rotational sliding that abrades the floor of the basin more than walls and that causes the bowl shape to form.
Glacial erosion landforms are those landforms formed by the erosive action of glaciers. Subcategories This category has the following 3 subcategories, out of 3 total.
Glacial erosion often causes U-shaped valleys to form. [6] These valleys allow for directed water movement such as seen in glacial streams with meltwater. [6] Subglacial fluvial erosion and glacial outwash occurs from the melting of the glacier and creates water flow that can wear bedrock. [4]
Drumlins and drumlin swarms are glacial landforms composed primarily of glacial till. They form near the margin of glacial systems, and within zones of fast flow deep within ice sheets, and are commonly found with other major glacially-formed features (including tunnel valleys, eskers, scours, and exposed bedrock erosion).
