Inuit build igloos where there is a lot of snow. First, they dig a large hole. The hole is the bottom of the igloo. Then they squeeze snow together. This forms blocks of ice. The blocks are stacked on one another. Igloos have a small hole on the top of the dome. Air moves in and out of the hole. This keeps the air inside safe to breathe.
