The Aztecs utilized their engineering skills to address island living challenges by constructing chinampas, floating gardens that increased agricultural productivity. They built causeways connecting their island capital to the mainland, facilitating transportation and trade. Additionally, they developed aqueducts and canals to manage water supply and drainage effectively.

The Aztecs also built intricate systems of dikes and levees to control flooding during the rainy season, allowing them to maintain a stable food supply. They used techniques such as terracing to create flat, fertile land for farming on the hilly terrain of their island capital.

In addition to their engineering prowess, the Aztecs were also skilled architects, constructing impressive temples, palaces, and other structures using stone, adobe, and wood. They utilized their knowledge of geometry and astronomy to align their buildings with the movements of the stars and to create accurate calendars.

Overall, the Aztecs' engineering and architectural achievements played a crucial role in their success as a civilization and allowed them to thrive in the challenging environment of their island capital.
