Final answer:
The Arctic people lived in igloos during the winter, which were effectively insulated and heated shelters suitable for the extreme cold. Cliff dwellings were associated with the Anasazi people, not the Arctic inhabitants. Shelter types varied among different indigenous peoples, with many adapting to their specific environments.
Step-by-step explanation:
The people of the Arctic lived in igloos during the winter. This is because the Inuit people of northern Alaska, Canada, and Greenland adapted to their extremely cold environment by constructing these dome-shaped homes out of snow and ice. The igloo's design and the insulating properties of the snow allowed for preservation of heat, and the compact space made it an effective shelter against the harsh Arctic climate.
In contrast, cliff dwellings were built by the Anasazi peoples, notable for their still-existing homes carved into cliffs. Tents and huts provided temporary shelters for Paleolithic humans as they did not construct true permanent houses. Prehistoric indigenous cave people typically lived in rock shelters or rock outcrops, while Sub-arctic Algonquin-speaking people led a nomadic lifestyle, relying on the abundance of natural resources for their survival.
