How were Aztecs different from anasazi and mound builder Indians?

The Aztecs were a Mesoamerican civilization known for their advanced urban society, including a powerful empire centered in present-day Mexico, characterized by monumental architecture like temples and a complex political system. In contrast, the Anasazi, located in the Southwest United States, were known for their cliff dwellings and agricultural practices, while the Mound Builders, primarily in the Eastern U.S., created large earthen mounds for ceremonial and burial purposes. While the Aztecs engaged in extensive trade and had a centralized governance, the Anasazi and Mound Builders were more decentralized and focused on regional trade and cooperation among smaller communities. Overall, these cultures varied significantly in their social structures, architectural styles, and geographic locations.
