An igloo is a type of shelter made from blocks of snow, commonly associated with the Inuit people of the Arctic. These unique structures are built in a dome shape, which helps them stay warm inside despite the freezing temperatures outside. The snow blocks are carefully cut and stacked, creating a strong and insulated home. Inside an igloo, the temperature can be surprisingly comfortable, often just a few degrees above freezing. The design allows for heat from a small fire or body warmth to be trapped inside. Igloos are not only practical but also showcase the incredible skills and knowledge of the Inuit in adapting to their harsh environment.
