Iglo Inuit Case Study

The Inuit build winter villages on see ice. How did they protect themselves from freezing arctic winds? They makes snow shelters called igloos. These shelters were very comfortable inside. They had a chimmney to circulate air. If the igloo became two cold, the Inuit plugged the chimney. If it became too warm, they widened the chimney. Igloos had windows to let light in. They had animal skins for insellation. Melting snow quickly freeze again and made an icey film. This sealed tiny holes in the walls and trapped heat inside the igloo. The temperature inside an igloo averaged 65 degrees warmer, than outside air with windchill. Built correctly, igloo's were very strong. kids could play on them and slide down there sides. Igloos weren't strong
enough to handle spring and summer. With warmer temperatures, the snow shelters melted. The Inuit had to pack up and move into tents until the next winter.
