Glacial valley, stream valley that has been glaciated, usually to a typical catenary, or U-shaped, cross section. U-shaped valleys occur in many parts of the world and are characteristic features of mountain glaciation.

19 paź 2023 · Glaciers are often called “ rivers of ice.”. Glaciers fall into two groups: alpine glaciers and ice sheets. Alpine glaciers form on mountainsides and move downward through valleys. Sometimes, alpine glaciers create or deepen valleys by pushing dirt, soil, and other materials out of their way.
A valley glacier is a type of glacier that flows down a mountain valley, often originating from an ice field or a larger ice mass. These glaciers are typically confined to the valley walls and are shaped by the landscape, carving out U-shaped valleys as they advance.
Valley glaciers are streams of flowing ice that are confined within steep walled valleys, often following the course of an ancient river valley. The downward erosive action of the ice carves the valley into a broad U shape, in contrast to the steeper V shape that is produced during the early stages of erosion by rivers.
Glacial landform, any product of flowing ice and meltwater. Such landforms are being produced today in glaciated areas, such as Greenland, Antarctica, and many of the world’s higher mountain ranges. In addition, large expansions of present-day glaciers have recurred during the course of Earth.
22 sie 2024 · Alpine glaciers (also called valley glaciers) originate high up in the mountains, mostly in temperate and polar regions (Figure 17.1), but also in tropical regions in high mountains (e.g. in the Andes Mountains of South America).
Glaciers are categorized by their morphology, thermal characteristics, and behavior. Alpine glaciers, also known as mountain glaciers or cirque glaciers, form on the crests and slopes of mountains. An alpine glacier that fills a valley is sometimes called a valley glacier.
