Glaciers - National Snow and Ice Data Center

Glaciers begin to form when snow remains in the same area year round, where enough snow accumulates to transform into ice. Each year, new layers of snow bury and compress the previous layers. This compression forces the snow to recrystallize, initially forming grains similar to the size and shape of sugar grains.

The Largest Glaciers and Glacier Complexes in the World, Version 1 data set provides a list of the three largest glaciers and glacier complexes in each of the 19 glacial regions of the world as defined by the Global Terrestrial Network for Glaciers. The data are provided in shapefile format with an outline for each of the largest ice bodies ...

There are over 200,000 glaciers distinct from the ice sheets; and if all of these glaciers were to melt, they would increase sea level by just under half a meter (1.6 feet). If the Greenland Ice Sheet were to melt, it would increase sea level by approximately 7.4 meters (24.3 feet) ; and if the Antarctic Ice Sheet were to melt, it would ...

Two categories of glaciers exist: ice sheets and alpine glaciers. Ice sheets cover vast areas of land in broad domes. Alpine glaciers, are smaller, and found not only at the poles, but in high mountain regions across the globe.

Once the glaciers receded, seawater covered the floor of the glacial trough to create fjords. The famous Matterhorn in Switzerland displays three types of glacial erosion: Cirques are created when glaciers erode the mountainside, scouring into it and creating rounded hollows with steep uphill faces, shaped like tilted bowls. A cirque is often ...

Movement of Glaciers. Glaciers move in one of two ways: internal flow or basal sliding. Internal flow happens due to the weight and shape of the ice. As the weight of the glacier puts pressure on ...

Glaciers are huge masses of ice, snow, rock, sediment, and often liquid water that originate on land and move down slope under the influence of their own weight and gravity. The two main types are continental glaciers (or ice sheets) and alpine glaciers.

Glaciers move at varying rates, from a couple of centimeters a day to up to about 30 meters a day. There are factors that increase glacial flow rates, such as a steeper slope, increased size and ...
What are glacial lakes? | National Snow and Ice Data Center
26 Apr 2025 at 3:12am
As Earth?s climate warms, the world?s glaciers are shrinking, increasing freshwater outputs to all kinds of glacial lakes. Some communities depend on glacial meltwater for seasonal irrigation or domestic use, but as the balance shifts toward more melt, this water source may not be reliable in the long term and comes with new risks.
Worldwide retreat of glaciers confirmed in unprecedented detail

Although some glaciers are maintaining their size, most glaciers are dwindling. The foremost cause of the worldwide reductions in glaciers is global warming, the team writes. The full-color book has twenty-five regional chapters that illustrate glacier changes from the Arctic to the Antarctic.
