How did the aztecs apply their engineering skills to the challenges of living on an island?

The Aztecs had remarkably impressive engineering skills, which helped them solve many of the difficulties of being located in an island.

One of the greatest examples of this, is the canal they built from the capital of Tenochtitlan, to Chapultepec, which helped them transport fresh water from the shores into the city. It was absolutely essential to their sustainability, as even though they had enough water for agriculture, it was salty water that couldn't be drank.

Hope this helps you out!

if interdependence implies a two-way dependence, and if each partner is equally dependent on the other for success, then there is an equal commitment to the making the partnership successful. the advantage is sustainability of the relationship, the disadvantage is that decisions are "democratic" and therefore may take longer to reach and more likely to be a compromise (which is not always the best solution). as the interdependence moves away from equality, the decisions become more influenced by the more independent partner. in the extreme the relationship becomes more dictatorial and more like "master-slave". generally the relationship has less commitment in both directions and is more likely to be temporary.

if one generalizes (and one shouldn't), equity partnerships, which is probably what is implied by interdependence, can be slow to progress or change but durable. the extreme alternative, independent-dependent partnerships tend to be efficient but more fragile.

hope this but you will have to site your own evidence. : )
