The Aztec empire was located in and around
the Vally of Mexico, a 7, 000 foot mountain basin with plenty of natural resources and fertile soil, which attracted many
newcomers. In addition, the climate was hot and humid and numerous lakes and mountains covered the area. The empire of the
Aztecs at its height reached 80,000 square miles and stretched from the Pacific Ocean to the Gulf Coast. To add to this,
the empire was populated by 15 million people living in more than 500 cities, one of these cities being Teotihuacan. Teotihuacan,
was then the capital of the Aztec Empire, and is now modern day Mexico City. To understand the topography better, look at
