Ice is water frozen into a solid state. It can appear transparent or opaque bluish-white color, depending on the presence of impurities or air inclusions. The addition of other materials such as soil may further alter its appearance.
The molecules in solid ice may be arranged in numerous different ways, called phases, depending on the temperature and pressure. Typically, ice is the phase known as ice Ih, which is the most abundant of the varying solid phases on Earth's surface The most common phase transition to ice Ih occurs when liquid water is cooled below 0°C (273.15K, 32°F) at standard atmospheric pressure. It can also deposit from vapour with no intervening liquid phase, such as in the formation of frost.
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.
