What is glacier?

  • (noun): A slowly moving mass of ice.

Glacier

A glacier ( /ˈɡlæsiə/ GLASS-ee-ər or /ˈɡleɪʃər/ GLAY-shər) is a large persistent body of ice that forms where the accumulation of snow exceeds its ablation (melting and sublimation) over many years, often centuries. At least 0.1 km2 in area and 50 m thick, but often much larger, a glacier slowly deforms and flows due to stresses induced by its weight. Crevasses, seracs, and other distinguishing features of a glacier are due to its flow. Another consequence of glacier flow is the transport of rock and debris abraded from its substrate and resultant landforms like cirques and moraines. Glaciers form on land, often elevated, and are distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water.

Famous quotes containing the word glacier:

    “The glacier knocks in the cupboard,
    The desert sighs in the bed,
    And the crack in the tea-cup opens
    A lane to the land of the dead.
    —W.H. (Wystan Hugh)
