The statement that accurately describes the Mississippian people and the Ancestral Puebloans is:
The Mississippian people lived in a region with a wet climate, whereas the Ancestral Puebloans lived in a dry climate.
The Mississippian culture was primarily located in the southeastern United States, featuring river valleys with fertile land, while the Ancestral Puebloans (formerly known as the Anasazi) inhabited the arid regions of the Southwest, including present-day Utah, Colorado, Arizona, and New Mexico.
