Question

Why are Igloos used in winter?

Answer 1

Igloos are used in winter because their construction compacted blocks of snow shaped into a dome traps air and acts as an excellent insulator, so the interior stays significantly warmer than the outside, the rounded shape sheds wind and prevents snow buildup, and features like a small entrance and interior linings for example seal skins reduce heat loss; this makes them an effective, readily available shelter for Arctic and tundra peoples (such as the Inuit) where winters are long and extremely cold and wood is scarce.
