Awesome
way to build an igloo. |
An igloo or snowhouse is a type of shelter built
of snow, originally built by the Inuit. Although
igloos are usually associated with all Inuit, they
were predominantly constructed by people of Canada's
Central Arctic and Greenland's Thule area. Other
Inuit people 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 -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.
