1. Temperate Highland (Mesa Central): This zone encompasses the Valley of Mexico where Tenochtitlan, the Aztec capital, was located. It is characterized by moderate temperatures, distinct seasons, and relatively abundant rainfall. This zone was ideal for agriculture, allowing the Aztecs to cultivate maize, beans, squash, and other crops.

2. Tropical Lowland (Coastal Plain): This zone is located along the Gulf Coast and Pacific Coast of Mexico. It experiences hot and humid temperatures year-round with heavy rainfall. The Aztecs had settlements in this region, which was important for trade routes and access to resources like cacao and tropical fruits.

3. Arid and Semi-Arid (Northern Mexico): While not as heavily populated by the Aztecs as the other two zones, this region was still important for trade and resource extraction. It is characterized by hot summers, cool winters, and low rainfall. The Aztecs obtained obsidian, a volcanic glass used for tools and weaponry, from this region.

It's important to note that the Aztecs also had settlements in other climate zones, but these three were the most significant for their cultural and economic development.
