An igloo is a type of shelter made from blocks of compressed snow, traditionally associated with the Inuit people of the Arctic regions. These structures are designed to provide warmth and protection from harsh weather conditions. The dome shape helps to distribute weight and resist strong winds, making igloos surprisingly sturdy. Igloos can vary in size, from small structures for a single person to larger ones that can accommodate families. The interior is often lined with animal skins or other materials to enhance insulation. Despite being made of snow, igloos can maintain a temperature that is warmer than the outside environment.
