It was too hot to grow food

There is too much water on the equator that all the plants get overwatered

It was too isolated, so they did not encounter enough people to get ideas from

It's harder to tell when to plant without changes in daylight and temperature

There were not many sources of drinkable water

There was little change in temperature or daylight hours to indicate seasonal change

Living on an island in the middle of large lake made it hard to have much farmland

The land was full of dense forests, mountains, and swamps

copying the examples of the earlier people of Teotihuacan

coming up with innovative solutions and changing their landscape

moving further north where they no longer had to worry about water scarcity

not doing anything, which backfired and led to the end of their civilization

the way parts of buildings were made to line up with the sun to tell farmers when to plant or harvest

the way in which they built with extra smooth marble and included double staircases

the way that they never included any 90 degree angles, keeping all shapes very organic

the way they built tall towers at the corners with large bells inside to call everyone to important ceremonies
