The glacier visible at the head of the valley is the last remnant of the formerly much more extensive glacier which carved it. U-shaped valley with lake in Myklebustdalen, Nordfjord, Sogn og Fjordane, Norway. U-shaped valleys, also called trough valleys or glacial troughs, are formed by the process of glaciation.
A glacier that fills a valley is called a valley glacier, or alternatively, an alpine glacier or mountain glacier. [9] A large body of glacial ice astride a mountain, mountain range, or volcano is termed an ice cap or ice field. [10] Ice caps have an area less than 50,000 km 2 (19,000 sq mi) by definition.
A valley is an elongated low area often running between hills or mountains and typically containing a river or stream running from one end to the other. Most valleys are formed by erosion of the land surface by rivers or streams over a very long period. Some valleys are formed through erosion by glacial ice.
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 old ...
Cirque. A cirque (French: [siʁk]; 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 [kʊm]). A cirque may also be a similarly shaped landform arising from ...
Geomorphology (from Ancient Greek: γῆ, gê, 'earth'; μορφή, morphḗ, 'form'; and λόγος, lógos, 'study') [2] is the scientific study of the origin and evolution of topographic and bathymetric features generated by physical, chemical or biological processes operating at or near Earth's surface. Geomorphologists seek to understand ...
Fjord. In physical geography, a fjord or fiord (/ ˈfjɔːrd, fiːˈɔːrd / ⓘ [1]) is a long, narrow sea inlet with steep sides or cliffs, created by a glacier. [2] Fjords exist on the coasts of Antarctica, the Arctic, and surrounding landmasses of the northern and southern hemispheres. [3]
Glaciology (from Latin glacies 'frost, ice' and Ancient Greek λόγος (logos) 'subject matter'; lit. 'study of ice') is the scientific study of glaciers, or, more generally, ice and natural phenomena that involve ice. Glaciology is an interdisciplinary Earth science that integrates geophysics, geology, physical geography, geomorphology ...
