igloo

An igloo (Inuit languages: , Inuktitut syllabics (plural: )), also known as a snow house or snow hut, is a type of shelter built of suitable snow. Although igloos are often associated with all Inuit, they were traditionally used only by the people of Canada's Central Arctic and the Qaanaaq area of Greenland. Other Inuit tended to use snow to insulate their houses, which were constructed from whalebone and hides. Snow is used because the air pockets trapped in it make it an insulator. On the outside, temperatures may be as low as , but on the inside, the temperature may range from when warmed by body heat alone. Nomenclature In the Inuit languages the word (plural ) can be used for a house or home built of any material. The word is not restricted exclusively to snowhouses (called specifically , plural ), but includes traditional tents, sod houses, homes constructed of driftwood and modern buildings. Outside Inuit culture, however, igloo refers exclusively to shelters constructed from blocks of compacted snow, generally in the form of a dome.
