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.
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 ...
Ice caps have an area less than 50,000 km 2 (19,000 sq mi) by definition. Glacial bodies larger than 50,000 km 2 (19,000 sq mi) are called ice sheets or continental glaciers. [11] Several kilometers deep, they obscure the underlying topography. Only nunataks protrude from their surfaces.
Most glacial rock glaciers are created by the recession of debris covered glaciers. [citation needed] Glacial rock glaciers are often found in cirque basins where rocky debris falls off the steep sides and accumulates on ice glaciers. [3] As the glaciers shrink, their composition changes as they become increasingly covered with debris.

Areas of study within glaciology include glacial history and the reconstruction of past glaciation. A glaciologist is a person who studies glaciers. A glacial geologist studies glacial deposits and glacial erosive features on the landscape. Glaciology and glacial geology are key areas of polar research.
