How An Igloo Keeps You Warm

The video explores how snow, despite being cold, serves as an effective insulator, particularly in igloos. It delves into the survival techniques of the Inuit in the Arctic, explaining how they use snow to build shelters. The video also covers the principles of heat transfer—convection, conduction, and radiation—and how these apply to igloos. It highlights the insulating properties of snow and animal adaptations, such as otter fur. The construction techniques for igloos are discussed, emphasizing the balance between snow density and insulation. Finally, the engineering behind igloos, including their catenary shape, is explained, showcasing their stability and thermal efficiency.
