Moving glaciers
Nettet24. aug. 2024 · At higher elevations, glaciers accumulate snow, which eventually becomes compressed into ice. At lower elevations, the “river” of ice naturally loses mass because of melting and ice breaking off and floating away (iceberg calving) if the glacier ends in a lake or the ocean. Nettet10. okt. 2024 · Glacier branches in the area of the Sognefjord. The Austdalsbreen glacier is a North-Eastern outlet from Jostedalsbreen. The glacier is east facing and ranges in height from 1200 to 1760 metres above sea level. The Bergset glacier, only an hour's easy walk from the road and is one of the most beautiful and impressing glacier arms.

A glacier is a slowly flowing mass of ice with incredible erosive capabilities. Valley glaciers (also known as alpine glaciers or mountain glaciers) excel at sculpting mountains into jagged ridges, peaks, and deep U-shaped valleys as these highly erosive rivers of ice progress down mountainous slopes. Valley … Se mer The area of glacial ice formation is called the zone of accumulation. In this zone more snow accumulates each winter than that which melts away … Se mer The area of a glacier that experiences a greater amount of melting than glacial ice formation is called the zone of wastage (zone of ablation). In … Se mer The upper 50 meters of the surface of the glacier, where the ice does not undergo plastic deformation, is referred to as the zone of fracture. In this … Se mer The line that separates the zone of accumulation from the zone of wastage is called the snow line (equilibrium line). The snow line may be visible at the end of summer between the … Se mer NettetThe fastest moving areas are glaciers and ice shelves along the edge of the ice, and of these, the Pine Island and Thwaites glaciers are moving most. The surprise, however, is that channels of fast-flowing ice extend far inland, broad tributaries feeding the glacial rivers. The ice sheet around the tributaries moves slowly, compressed by its ...

Ice behaves like a brittle solid until its thickness exceeds about 50 m (160 ft). The pressure on ice deeper than 50 m causes plastic flow.
