Glacier - Wikipedia
On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand.
Glacier Quick Facts - National Snow and Ice Data Center
Presently, 10 percent of land area on Earth is covered with glacial ice, including glaciers, ice caps, and the ice sheets of Greenland and Antarctica. Glacierized areas cover over 15 million square kilometers (5.8 million square miles).
Glaciers - National Snow and Ice Data Center
Alpine glaciers are frozen rivers of ice, slowly flowing under their own weight down mountainsides and into valleys. Glaciers also exist on the fringes of ice sheets. Ice sheets cover entire continents.
List of glaciers - Wikipedia
The lists include outlet glaciers, valley glaciers, cirque glaciers, tidewater glaciers and ice streams. 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.
Glaciers: Moving Rivers of Ice - National Geographic Society
Oct 19, 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.
Ice field - Wikipedia
An ice field (also spelled icefield) is a mass of interconnected valley glaciers (also called mountain glaciers or alpine glaciers) on a mountain mass with protruding rock ridges or summits. [1] They are often found in the colder climates and higher altitudes of the world where there is sufficient precipitation for them to form.

Jan 2, 2025 · Glaciers in the third group are not independent and are treated here in terms of their sources: ice shelves with ice sheets, piedmont glaciers with mountain glaciers. A complex of mountain glaciers burying much of a mountain range is called an ice field.
Glacier - Formation, Movement, Retreat | Britannica
Jan 2, 2025 · Glacier - Formation, Movement, Retreat: In this discussion the term mountain glaciers includes all perennial ice masses other than the Antarctic and Greenland ice sheets. Those ice masses are not necessarily associated with mountains.
Science of Glaciers | National Snow and Ice Data Center
The sheer weight of a thick layer of ice, or the force of gravity on the ice mass, causes glaciers to flow. Ice is a soft material, in comparison to rock, and is much more easily deformed by this relentless pressure of its own weight. Ice may flow down mountain valleys, fan out across plains, or in some locations, spread out onto the sea.
Glaciers: How do they form and how do they move? - Geology.com
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.
