isbreene
Isbreene are large, persistent bodies of dense ice that form on land from the accumulation, compaction, and recrystallization of snow over many years. They move slowly under gravity, flowing and deforming, which sculpts valleys and other landscapes. The upper part gains mass through snowfall (accumulation), while the terminus loses ice through melting, sublimation, and calving (ablation). The boundary between accumulation and ablation is the equilibrium line; climate changes shift this line and cause glaciers to advance or retreat.
Glaciers are classified by shape and location: valley glaciers occupy mountain valleys; ice sheets cover wide
Glaciers erode and transport material, creating features such as U-shaped valleys, moraines, and fjords. They are
In Norwegian, isbreene refers to the glaciers, with isbre the term for a glacier and isbreene the
