Greenland

The average annual temperatures of Nuuk, Greenland vary from -9 to 7 °C (15.8 to 44.6 °F)
The Atlantic Ocean borders Greenland's southeast; the Greenland Sea is to the east; the Arctic Ocean is to the north; and Baffin Bay is to the west. The nearest countries are Iceland, east of Greenland in the Atlantic Ocean, and Canada, to the west across Baffin Bay. Greenland also contains the world's largest national park, and is the world's largest island and the largest dependent territory by area in the world. However, since the 1950s, scientists have postulated that the ice sheet covering the country may actually conceal three separate island land masses that have been bridged by glaciers over the last geologic cooling period.
The total area of Greenland is 2,166,086 km2 (836,330 sq mi), of which the Greenland ice sheet covers 1,755,637 km2 (677,855 sq mi) (81%) and has a volume of approximately 2,850,000 cubic kilometres (680,000 cu mi). The highest point on Greenland is Gunnbjørn Fjeld at 3,700 metres (12,139 ft). The majority of Greenland, however, is less than 1,500 metres (4,921 ft) in elevation.
The weight of the massive Greenland ice sheet has depressed the central land area to form a basin lying more than 300 m (984 ft) below sea level. The ice flows generally to the coast from the center of the island.
