Greenland is located between the Arctic Ocean and the North Atlantic Ocean, northeast of Canada and northwest of Iceland. The territory comprises the island of Greenland - the largest island in the world - and more than a hundred other smaller islands (see ). An island, Greenland has no land boundaries and 44,087 km of coastline. A sparse population is confined to small settlements along the coasts. Greenland possesses the world's second largest ice sheet. Greenland sits atop the Greenland plate, a subplate of the North American plate. The Greenland craton is made up of some of the oldest rocks on the face of the earth. The Isua greenstone belt in southwestern Greenland contains the oldest known rocks on Earth, dated at 3.7–3.8 billion years old.〔Appel, Peter W.U., Hugh R. Rollinson, and Jacques L.R. Touret.

The climate is arctic to subarctic, with cool summers and cold winters. The terrain is mostly a flat but gradually sloping icecap that covers all land except for a narrow, mountainous, barren, rocky coast. The lowest elevation is sea level and the highest elevation is the summit of Gunnbjørn Fjeld, the highest point in the Arctic at . The northernmost point of the Island of Greenland is Cape Morris Jesup, discovered by Admiral Robert Peary in 1909. Natural resources include zinc, lead, iron ore, coal, molybdenum, gold, platinum, uranium, and fish. ==Area== ''total:'' 2,166,086 km² ''land:'' 2,166,086 km² (410,449 km² ice-free, 1,755,637 km² ice-covered) Maritime claims: ''territorial sea:'' ''exclusive fishing zone:'' 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Geography of Greenland」の詳細全文を読む スポンサード リンク
