An igloo is a type of ice structure traditionally built by the Inuit people of the Arctic region. It is constructed from blocks of snow and is designed to provide shelter from the cold temperatures and harsh winds of the Arctic. The word 'igloo' comes from the Inuit language and means 'HOUSE'. Igloos are typically dome-shaped and can range in size from small, single-person dwellings to large, multi-room structures. They are still used today by the Inuit people for temporary housing during hunting trips and other activities.
