Government. In 1951, Greenland became an itegral part of Denmark under the Danish prime linister, who is represented in Greenland by a Dvemor. Greenland is divided into two con-ituencies and elects two representatives to the •anish parliament. The local administration of orth and east Greenland is directly in the prime linister's department; west Greenland elects its m councils to carry out administrative work.
The Antarctic ice sheet has an area about one and a half times as large as the USA - 13 million square kilometres (5 million square miles), and it holds nine times more ice than the Greenland ice sheet, 25 million cubic kilometres (6 million cubic miles). The ice thickness reaches up to 4km (2.5 miles). This mass flows north and reaches the sea through outlet glaciers and ice shelves that are floating extensions of the ice sheet. The shorelines of the shelves are constantly moving, shedding huge tabular icebergs that are sometimes known as ice islands.
The Greenland ice sheet occupies 1,740,000 square kilometres (670,000 square miles), 80 per cent of the island's area, and has a volume of 2,800,000 cubic kilometres (672,000 cubic miles). Its average thickness is 1.6km (1 mile) and it reaches as much as 3km (1.9 miles) at the centre.
