An igloo (Inuit language: iglu, Inuktitut syllabics: ᐃᒡᓗ, "house", plural: iglooit or igluit, but in English commonly igloos), translated sometimes as snowhouse, is a shelter constructed from blocks of snow, generally in the form of a dome. The Inuit language is traditionally spoken across the North American Arctic and to some extent in the Subarctic in Labrador. The Inuktitut syllabary ( Inuktitut: ᑎᑎᕋᐅᓯᖅ ᓄᑖᖅ titirausiq nutaaq) is a Writing system (specifically an Abugida "Snowfall" redirects here For other uses see Snow (disambiguation or Snowfall (disambiguation. A dome is a common structural element of Architecture that resembles the hollow upper half of a Sphere. Although igloos are usually associated with all Inuit, they were predominantly constructed by people of Canada's Central Arctic and Greenlands Thule area. Inuit (plural the singular Inuk, means "man" or "person" is a general term for a group of culturally similar Indigenous peoples inhabiting Country to "Dominion of Canada" or "Canadian Federation" or anything else please read the Talk Page Greenland (Kalaallit Nunaat meaning "Land of the Greenlanders" Grønland is a self-governing Danish Province located between the Qaanaaq (qaːnaːq is a town and Municipality in northwestern Greenland. Other Inuit people tended to use snow to insulate their houses which consisted of whalebone and hides. The use of snow is due to the fact that snow is an insulator (due to its low density). On the outside, temperatures may be as low as −45 °C (−49 °F), but on the inside the temperature may range from −7 °C (19 °F) to 16 °C (61 °F) when warmed by body heat alone[1]. The Celsius Temperature scale was previously known as the centigrade scale. Fahrenheit is a temperature scale named after Daniel Gabriel Fahrenheit (1686–1736 a German Physicist who proposed it in 1724

The Central Inuit, especially those around the Davis Strait, line the living area with skin, which can increase the temperature within from around 2 °C (36 °F) to 10-20 °C (50-68 °F). Davis Strait (Détroit de Davis lies between mid-western Greenland and Baffin Island in the Canadian territory of
Constructing an igloo
The snow used to build an igloo must have sufficient structural strength to be cut and stacked in the appropriate manner. The best snow to use for this purpose is snow which has been blown by wind, which can serve to compact and interlock the ice crystals. The hole left in the snow where the blocks are cut from is usually used as the lower half of the shelter. Sometimes, a short tunnel is constructed at the entrance to reduce wind and heat loss when the door is opened. Due to snow's excellent insulating properties, inhabited igloos are surprisingly comfortable and warm inside. In some cases a single block of ice is inserted to allow light into the igloo.
Architecturally, the igloo is unique in that it is a dome that can be raised out of independent blocks leaning on each other and polished to fit without an additional supporting structure during construction. The term architecture (from Greek αρχιτεκτονικήarchitektoniki) can be used to mean a process a profession or documentation The igloo, if correctly built, will support the weight of a person standing on the roof. Also, in the traditional Inuit igloo the heat from the kulliq (stone lamp) caused the interior to melt slightly. This melting and refreezing built up an ice sheet and contributed to the strength of the igloo. [2]
The sleeping platform is a raised area compared to where one enters the igloo. Because warmer air rises and cooler air settles, the entrance area will act as a cold trap whereas the sleeping area will hold whatever heat is generated by a stove, lamp or body heat.
Heraldry
In heraldry, the igloo appears as the crest in the coat of arms of Nunavut. Heraldry in its most general sense encompasses all matters relating to the duties and responsibilities of officers of arms. The Coat of Arms of the Territory of Nunavut (formally known as The Arms of Her Majesty in Right of Nunavut) was granted by a warrant by Roméo LeBlanc Nunavut (ˈnuːnəvʊt ( Inuktitut syllabics: ᓄᓇᕗᑦ is the largest and newest territory of Canada; it was separated officially from the
