Greenland has a 1.2-kilometer-long (0.75 mi) border with Canada on Hans Island. [1] A sparse population is confined to small settlements along certain sectors of the coast. Greenland possesses the world's second-largest ice sheet. Greenland sits atop the Greenland plate, a subplate of the North American Plate.
Greenland ice sheet as seen from space. An ice sheet is a body of ice which covers a land area of continental size - meaning that it exceeds 50,000 km 2. [4] The currently existing two ice sheets in Greenland and Antarctica have a much greater area than this minimum definition, measuring at 1.7 million km 2 and 14 million km 2, respectively.
The Greenland ice sheet is an ice sheet which forms the second largest body of ice in the world. It is an average of 1.67 km (1.0 mi) thick, and over 3 km (1.9 mi) thick at its maximum. [2]
The ICESat mission was designed to provide elevation data needed to determine ice sheet mass balance as well as cloud property information, especially for stratospheric clouds common over polar areas. It provides topography and vegetation data around the globe, in addition to the polar-specific coverage over the Greenland and Antarctic ice sheets.
The first US-sponsored installations at Thule were established after the US Secretary of State Cordell Hull and the defected Danish Minister to the United States Henrik Kauffmann signed The Agreement relating to the Defense of Greenland in Washington, D.C., on the symbolically chosen date of 9 April 1941.

The geology of Greenland is dominated by crystalline rocks of the Precambrian Shield. [1] The crystalline rocks of the Nuuk/Qeqertarsuatsiaat area comprise some of the oldest bedrock in Greenland which covers most of western Greenland. The surface has been altered several times and has an appearance as though it were shaped billions of years ago.
Below is a list of countries and dependencies in North America by area. [1] The region includes Canada, the Caribbean, Saint Pierre and Miquelon, Central America, Greenland, Mexico, and the United States. Canada is the largest country in North America and the Western Hemisphere.
This is a complete list of all 50 U.S. states, its federal district (Washington, D.C.) and its major territories ordered by total area, land area and water area. [1] The water area includes inland waters, coastal waters, the Great Lakes and territorial waters. Glaciers and intermittent bodies of water are counted as land area. [2]
