Essential Terms Associated With Ice

Ice is the solid form of water, formed by freezing, the compaction of snow and the condensation of water vapour directly into crystals. The density of the ice is 0.9166, that is less than water, and thus Ice floats.
Ice Age- A geological period of widespread glacial activity, when Ice sheets covered large parts of the continents is called Ice Age.
Ice Barrier- The edge of the Ancient ice sheet is called ice barrier, for example, the Ross Ice Barrier.
Ice Blink- The glare from the underside of a cloud layer, produced by the reflection from an ice surface below, as in the case of an ice sheet or of pack ice, is called ice blink. This may produce eye irritation and even snow blindness.
Ice Cap- A permanent mass of ice covering plateaus and high latitude islands, but smaller than an ice sheet; for example Spitsbergen; Novaya Zemlya; Franz Josef Land
Ice Dam- A dam on river caused by clocks of ice, which may result in widespread flooding in spring and early summer, is called ice dam, as along the Siberian and Canadian rivers (also called Ice Jam)
Ice Edge-The boundary between open water and a mass of floating sea ice.
Ice- Field- The term refers to a large continuous area of Packice or sea ice by both USA and Britain definition. Generally it is used much more widely; for example, the Columbia Ice field in Jasper National Park, Alberta, Canada which is 130 square miles in area.
Ice Fall- A confused labyrinth of deep clefts and ice pinnacles formed by the intersection of ‘crevasses’ where a glacier steepens, is called Ice fall, for example, the glaciers moving down from the flanks of Mont Blank to the Chamonix valley, descending over 6000 feet in only 2 miles. The huge Khumbu ice fall was a major obstacle in the approach of dimbers to the South Col. Of Everest.
Ice Floe- a thin, detached, floating horizontal sheet of sea ice is called Floe; hence Ice Floe.
Ice Fog- A fog consisting of minute ice crystals suspended in the air, in conditions of calm air and low temperatures, is called Ice fog.
Ice Front- A cliff of ice, the seaward face of a floating mass of ice, such as an ice shelf or tidal glacier, is called an Ice Front.
Ice Jam- A mass of broken ice fragments, especially during spring melting jammed in a narrow channel, causing flooding is called Ice Jam.
Icelandic Low- The mean sub polar atmospheric low pressure area in the North Atlantic Ocean between Iceland and Greenland, most marked in winter, it is not a very intense, stationary ‘low’, but an area of rapidly moving individual ‘lows’, interrupted by occasional periods of higher pressure.
Ice Shelf-A large floating ice sheet attached to the coastline is called an Ice Shelf for example, the Ross Ice Shelf.
