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 ...
Tunnel valley – Glacial-formed geographic feature; Turlough – Type of seasonal or periodic lake found in limestone areas of Ireland; Tuya – Flat-topped, steep-sided volcano formed when lava erupts through a thick glacier or ice sheet; U-shaped valley – Valleys formed by glacial scouring; Uvala – Toponym for a closed karst depression
Fluvio-glacial landforms and erosional surfaces include: outwash plains, kames, kame terraces, kettle holes, eskers, varves, and proglacial lakes. [4] Meltwater streams and formed by glaciers, especially in warmer seasons. Supra-glacial streams, those above the glacial surface, and subglacial streams, those beneath the glacial surface. [5]
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]
Glacial landform – Landform created by the action of glaciers; Drumlin – Elongated hill formed by glacial action; Esker – Long, winding ridge of stratified sand and gravel associated with former glaciers; Moraine-dammed lake – Type of lake formed by glaciation; Terminal moraine – Type of moraine that forms at the terminal of a glacier
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).

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 term "glacial series" is restricted to landforms created by glaciers and classified by geomorphological rules, as opposed to the glacial sediments and sedimentary rocks associated with glaciers and classified by their geological features. A complete glacial series is formed when the edge of the ice sheet remains static for a long time and ...
