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. They are characteristic of mountain glaciation in particular. [1] They have a characteristic U shape in cross-section, with steep, straight sides and a flat ...
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.
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 ...
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.
Yosemite Valley (/ joʊˈsɛməti / yoh-SEM-ə-tee; Yosemite, Miwok for "killer") is a glacial valley in Yosemite National Park in the western Sierra Nevada mountains of Central California, United States. The valley is about 7.5 mi (12.1 km) long and 3,000–3,500 ft (910–1,070 m) deep, surrounded by high granite summits such as Half Dome and ...
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 ...
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]
a glacial meltwater valley, the Urstromtal, through which meltwaters from the glacier flowed away. 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 ...
