At some point, if an Alpine glacier becomes too thin it will stop moving. This will result in the end of any basal erosion. The stream issuing from the glacier will then become clearer as glacial flour diminishes. Lakes and ponds can also be caused by glacial movement. Kettle lakes form when a retreating glacier leaves behind an underground ...
Velocity map of Antarctica. Ice streams can be seen with increasing speeds (blue-yellow-white) flowing toward the coast. [1] Radarsat image of ice streams flowing into the Filchner-Ronne Ice Shelf. An ice stream is a region of fast-moving ice within an ice sheet. It is a type of glacier, a body of ice that moves under its own weight. [2]
Land terminating glacier velocities decline as the terminus is approached. Calving glaciers accelerate at the terminus. A declining velocity near the terminus slows the glacier response to climate. An accelerating velocity at the front enhances the speed of the glaciers response to climate or glacier dynamic changes.
Nioghalvfjerdsbræ), sometimes referred to as "79 N Glacier", is a large glacier located in King Frederick VIII Land, northeastern GreenlandIt drains an area of 103,314 km 2 (39,890 sq mi) of the Greenland Ice Sheet with a flux (quantity of ice moved from the land to the sea) of 14.3 km 3 (3.4 cu mi) per year, as measured for 1996.

A glacier stream is a channelized area that is formed by a glacier in which liquid water accumulates and flows. [1] Glacial streams are also commonly referred to as "glacier stream" or/and "glacial meltwater stream". The movement of the water is influenced and directed by gravity and the melting of ice. [1]
Pine Island Glacier (PIG) is a large ice stream, and the fastest melting glacier in Antarctica, responsible for about 25% of Antarctica's ice loss. [3] The glacier ice streams flow west-northwest along the south side of the Hudson Mountains into Pine Island Bay , Amundsen Sea , Antarctica .
The glacier has been in a quiescent state since, although there are suggestions it will reach the required pre-surge conditions by 2027–2030. Grounding-line retreat is noted by the same article to be approximately 400m/yr, and the "dynamic cycling" of temperature and precipitation (which alters glacier mass-balance) is thought to be causing this.
Ice streams are a type of glacier [5] and many of them have "glacier" in their name, e.g. Pine Island Glacier. Ice shelves are listed separately in the List of Antarctic ice shelves. For the purposes of these lists, the Antarctic is defined as any latitude further south than 60° (the continental limit according to the Antarctic Treaty System). [6]
