A mass of land ice that is formed by the cumulative recrystallization of firn A glacier flows slowly (at present or in the past) from an accumulation area to an ablation area Some well-known glaciers are: the Zermatt, Stechelberg, Grindelwald, Trient, Les Diablerets, and Rhone in Switzerland; the Nigards, Gaupne, Fanarak, Lom, and Bover in Norway; the Wright, Taylor, and Wilson Piedmont glaciers in Antarctica; the Bossons Glacier in France; the Emmons and Nisqually glaciers on Mt Ranier, Washington; Grinnell glacier in Glacier National Park, Montana; the Dinwoody glacier in the Wind River Mountains and the Teton glacier in Teton National Park, both in Wyoming; and many glaciers in the Canadian Rockies (Source: Carbon Dioxide Information Analysis Center, 1990)
is a multi-year accumulation of snowfall in excess of snow melt on land, resulting in a mass of ice covering at least a tenth of a square kilometer, that shows some evidence of movement in response to gravity Glacier ice is the largest reservoir of fresh water on Earth, and second only to the oceans as the largest reservoir of total water Glaciers are found on every continent except Australia
a huge mass of ice and snow which moves extremely slowly (inches per year); able to scrape off and move large amounts of earth
A multi-year surplus accumulation of snowfall in excess of snowmelt on land and resulting in a mass of ice at least 0 1 km2 in area that shows some evidence of movement in response to gravity A glacier may terminate on land or in water Glacier ice is the largest reservoir of fresh water on Earth, and second only to the oceans as the largest reservoir of total water Glaciers are found on every continent except Australia
A slowly moving mass of ice formed by an accumulation of snow During the last ICE AGE there were glaciers in Britain
A large body of ice that moves down a mountainside from highlands toward sea level
Bodies of land ice that consist of recrystallized snow accumulated on the surface of the ground (Matthes, 1949, p 150), and that move slowly downslope
A large mass of ice and snow that forms when the rate of snowfall constantly exceeds the rate at which snow melts; most often associated with the Ice Age, in which large parts of the earth were covered with glaciers
A glacier is an extremely large mass of ice which moves very slowly, often down a mountain valley. a large mass of ice which moves slowly down a mountain valley (glace , from glacies). Large mass of perennial ice that forms on land through the recrystallization of snow and that moves forward under its own weight. The term ice sheet is commonly applied to a glacier that occupies an extensive tract of relatively level land and that flows from the centre outward. Glaciers occur where snowfall in winter exceeds melting in summer, conditions that prevail only in high mountain areas and polar regions. Glaciers occupy about 11% of the Earth's land surface but hold roughly three-fourths of its fresh water; 99% of glacier ice lies in Antarctica and Greenland.

a body of ice, consisting largely of recrystalized snow, that shows evidence of downslide movement due to its own weight
An immense field or stream of ice, formed in the region of perpetual snow, and moving slowly down a mountain slope or valley, as in the Alps, or over an extended area, as in Greenland
A large mass of ice formed, at least in part, on land by the compaction and recrystallization of snow, moving slowly down slope or outward in all directions due to the stress of its own weight and surviving from year to year The term "glacier" is usually, though not exclusively, confined to ice bodies that are constrained by valleys Ice bodies that are continental in scale are usually called "ice sheets"
A large tongue of ice that flows down a slope A glacier which flows entirely within a valley is sometimes called a valley glacier If a glacier comes out of mountains and spreads out onto a plain, it becomes part of an ice sheet If valley glaciers fill their valleys during an ice age, the ice spills over the crests to make a mountain ice cap, or if larger, a mountain ice sheet
Mass of ice that flows under its own weight by internal deformation of ice, basal sliding, or other mechanisms
a large mass of ice formed when more snow falls than melts every year As the glacier moves downhill, it creates a variety of landforms
