  • A glacier (US /ˈɡleɪʃər/ or UK /ˈɡlæsiə/) is a persistent body of dense ice that is constantly moving under its own weight; it forms where the accumulation of snow exceeds its ablation (melting and sublimation) over many years, often centuries.
  • Glaciers slowly deform and flow due to stresses induced by their weight, creating crevasses, seracs, and other distinguishing features. T

  • The volume of ice is so large that if the Greenland ice sheet melted, it would cause sea levels to rise six meters (20 ft) all around the world. If the Antarctic ice sheet melted, sea levels would rise up to 65 meters (210 ft)
  • The distinctive blue tint of glacial ice is often wrongly attributed to Rayleigh scattering due to bubbles in the ice. The blue color is actually created for the same reason that water is blue, that is, its slight absorption of red light due to an overtone of the infrared OH stretching mode of the water molecule.^[9]

  • A glacier (pronounced UK: /ˈɡlæsiər/ GLASS-ee-ər  or US: /ˈɡleɪʃər/ GLAY-shər)  is a perennial mass of ice which moves over  land. A glacier forms in locations where the mass accumulation of snow and ice  exceeds ablation over many years.  The word glacier comes from French via the Vulgar Latin glacia, and ultimately from Latin glacies meaning ice.

  •   Glacier  
  • Glacier ice is the largest reservoir of fresh water on Earth, and is second only to oceans as the largest reservoir of total water. Glaciers  cover vast areas of the polar  regions and are found in mountain ranges
  • Alpine glaciers
  • Alpine glaciers form on mountain slopes and are also known as mountain,  niche or cirque glaciers. An Alpine  glacier that fills a valley is referred to as a Valley glacier. Larger  glaciers that cover an entire mountain, mountain chain or volcano are known as an ice cap or ice field
  • Ice sheets are the largest glaciers. These enormous masses of ice are not  visibly affected by the landscape as they cover the entire surface beneath them,  with possible exception near the glacier margins where they are thinnest. Antarctica and Greenland are the only places where Continental ice sheets  currently exist.

  • Antarctic ice  sheet melted, sea levels would rise up to 65 meters (210 ft).^[3] Ice shelves  are areas of floating ice, commonly located at the margin of an ice sheet.

  • Two common types of glaciers are Alpine glaciers, which originate in mountains, and Continental ice sheets, which cover larger areas.
