In glaciology, an ice cap is a mass of ice that covers less than 50,000 km 2 (19,000 sq mi) of land area (usually covering a highland area). Larger ice masses covering more than 50,000 km 2 (19,000 sq mi) are termed ice sheets .
Wire shelving for industrial use consists of steel wire, used for the decking, and steel sheets, used for the supports. The wire makes up about 60% of the weight and the sheet steel about 40%. Coiled steel wire is cut to the correct lengths required using straight-cut machines.
In ice sheets, domes may reach a thickness that may exceed 3,000 meters (9,800 feet). However, in ice caps, the thickness of the dome is much smaller, measuring roughly up to several hundred metres in comparison. [5] In glaciated islands, ice domes are usually the highest point of the ice cap. [5]
Some named Antarctic iceshelves. Ice shelf extending approximately 6 miles into the Antarctic Sound from Joinville Island. An ice shelf is "a floating slab of ice originating from land of considerable thickness extending from the coast (usually of great horizontal extent with a very gently sloping surface), resulting from the flow of ice sheets, initially formed by the accumulation of snow ...
The Fennoscandian Ice Sheet of the Weichselian glaciation most likely grew out of a mountain glaciation of small ice fields and ice caps in the Scandinavian Mountains.The initial glaciation of the Scandinavian Mountains would have been enabled by moisture coming from the Atlantic Ocean and the mountains high altitude.
Glaciers often form on the edges of ice fields, serving as gravity-propelled drains off the ice field which is in turn replenished by snowfall. While an ice cap is not constrained by topography, an ice field is. An ice field is also distinguishable from an ice cap because it does not have a dome-like form. [2]

It is the time period in which the Antarctic ice cap has existed. The Vashon Glaciation lasted from about 19,000 – 16,000 BP (Before Present – present defined as January 1, 1950 for this scale). The Cordilleran Ice Sheet was an ice sheet that covered present-day southern Alaska and parts of western Canada.
