How did groups of the south west differ from those in the great plains and why?

Groups in the Southwest, such as the Pueblo and Navajo, typically engaged in agriculture and had more permanent settlements, utilizing irrigation techniques to support farming in arid environments. In contrast, the Great Plains tribes, like the Sioux and Cheyenne, were primarily nomadic, relying on buffalo hunting and following herds across vast grasslands. These differences arose largely due to variations in geography and climate, which influenced their subsistence strategies and social structures. As a result, the cultures and lifestyles of these groups reflected their distinct environments and available resources.
