An iceberg is a large piece of freshwater ice that has broken off a glacier or an ice shelf and is floating freely in open water. It may subsequently become frozen into pack ice (one form of sea ice). As it drifts into shallower waters, it may come into contact with the seabed, a process referred to as seabed gouging by ice.
Greenland (Greenlandic: Kalaallit Nunaat[kaˈla:ɫitˈnuna:t]) is an autonomouscountry within the Kingdom of Denmark, located between the Arctic and Atlantic Oceans, east of the Canadian Arctic Archipelago. Though physiographically a part of the continent of North America, Greenland has been politically and culturally associated with Europe (specifically Norway and later Denmark) for more than a millennium. In 2008, the people of Greenland passed a referendum supporting greater autonomy; 75% of votes cast were in favour. Greenland is, in terms of area, the world's largest island, over 3/4 of which is covered by the only contemporary ice sheet outside of Antarctica. With a population of 56,370 (2013), it is the least densely populated country in the world.
