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 higher amount of inland glacial melt ultimately increases the amount of outlet glacier output. [14] Studies predict that outlet glaciers found in Greenland can increase the global sea level considerably following an increase in global temperature, and a subsequently higher drainage output. [15] Examples include: [14] Helheim Glacier, Greenland
In geography, a glacial deposit is a glacial landform, composed of sediments of varying size, from clay through sand to boulders, deposited in the landscape when the glacier withdraws. Subcategories This category has the following 3 subcategories, out of 3 total.
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).

Landform comprising an immense pile of calcareous material previously accumulated on an ancient sea floor. Reef knolls can be divided into bioherms and biostromes. A bioherm is a landform of organic sedimentary rock enclosed or surrounded by rock of different origins. A biostrome is a distinctly bedded or broadly lenticular sedimentary rock ...
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 ]

Glacial streams are also commonly referred to as "glacier stream" or/and "glacial meltwater stream". The movement of the water is influenced and directed by gravity and the melting of ice. [1] The melting of ice forms different types of glacial streams such as supraglacial, englacial, subglacial and proglacial streams. [1]
