Nunavut dwellers traditionally live in igloos, which are dome-shaped dwellings made of blocks of snow and ice. Igloos are built to provide shelter from the harsh Arctic climate and have been used by Inuit people for centuries. They are constructed using a variety of tools, including snow knives, shovels, and saws. The interior of an igloo is usually lined with animal skins or furs to provide insulation and warmth.
