I WONDER - What Is An Igloo?

Igloos, or snow houses, are dome-shaped structures made from compacted snow blocks, primarily found in Arctic regions inhabited by the Inuit. These blocks are arranged in a spiral pattern with a small entrance to block cold winds. Snow's insulating properties allow igloos to maintain a warm interior, making them ideal temporary shelters for hunters and travelers in cold environments.
