True or False? The Most Enduring Myths About Snow and Ice

Igloos Are Warm Inside: The Insulating Power of Snow

The idea that igloos are warm inside seems paradoxical but is grounded in the insulating properties of snow. Snow is composed of tiny air pockets trapped within its structure, making it an excellent insulator. When constructed properly, an igloo can maintain an interior temperature well above freezing, even when outside temperatures plummet. The compacted snow blocks used in igloo construction reduce heat transfer, while the dome shape minimizes surface area exposed to the cold. This ingenious use of natural materials by indigenous Arctic peoples exemplifies how understanding snow's properties can transform a myth into an effective survival strategy.
