Answer – The largest, non-continental island in the world is Greenland.
Explanation:
Greenland spans an expanse of 2,166,086 square kilometers and is renowned for its extensive tundra and enormous glaciers. Approximately two-thirds of the island is situated within the Arctic Circle, with its northernmost point reaching to within less than 500 miles (800 kilometers) of the North Pole. The Greenland Ice Sheet has an average thickness of 5,000 feet, encompassing a territory exceeding 700,000 square miles. This accounts for over four-fifths of Greenland’s total land area.
