When used to refer to a snowhouse an igloo is a shelter constructed from blocks

of snow, generally in the form of a dome. Although igloos are usuallyassociated with

all Inuit, they were predominantly constructed by people ofCanada's Central Arctic and

Greenlands Thule area. Other Inuit people tendedto use snow to insulate their houses

which consisted of whalebone and hides.Snow was used because its low density

makes it an insulator. On the outside,temperatures may be as low as −45 °C (−49.0 °F),

but on the inside thetemperature may range from −7 °C (19 °F) to 16 °C (61 °F) when

warmed bybody heat alone.In this story you can see how igloo look inside,some pictures
