1. What is the structural material?Blocks of wind-packed snow
2. What is the architectural form?Self-supporting dome or vaulted structure
3. How does an igloo stay warm?The dome shape spreads weight, and the snow’s tiny air pockets trap heat. A low entrance keeps warm air inside, and a seal‑oil lamp adds extra warmth.
4. Why do igloos have a dome shape?The dome spreads the weight of the snow evenly, so the structure can hold snow and wind pressure without collapsing.

Vernacular architecture: Architecture that arises from local needs and is based on local materials and traditions.
Passive solar design: Using the sun's energy for heating and cooling without active mechanical systems.
Cold trap: A design feature that prevents cold air from entering a space by keeping it at a lower level than the living area.
