Example 1: In the Arctic, where it's very cold, Inuit people make igloos to protect themselves from the harsh weather.
Example 2: During the winter in very snowy places, people can build igloos to play in or stay warm while camping.
Example 3: An igloo can be made from hard snow blocks that are shaped and stacked carefully to create a cozy home.
Fun Fact: Igloos are very special because even when it's freezing outside, they can be warm inside due to the way they are built!
