Which is an example of how the physical environment helped the aztecs, establish an Empire.

The physical environment of the Valley of Mexico helped the Aztecs establish their empire in several ways. One example is the presence of Lake Texcoco, which provided a natural defense barrier against potential enemies. The lake also provided a reliable source of water for irrigation and agriculture, allowing the Aztecs to develop a sophisticated system of terraced farming and increase their food production. Additionally, the fertile soil around the lake supported the cultivation of crops such as maize, beans, and squash, which formed the basis of the Aztec diet. Overall, the favorable physical environment of the Valley of Mexico played a crucial role in the Aztecs' ability to grow and sustain their empire.
