Why do you think the Mayans built their cities in the rainforest?
Please provide an explanation.

For the water, and to avoid droughts/dry climates

Their ability to create a great civilization in a tropical rainforest environment was one of the many interesting things about the Maya. Ancient cultures have historically flourished in drier climates, where the foundation of civilization was the centralized control of water supplies (through irrigation and other techniques).

the geography of greece

led to limited interactions with other cultures in the mediterranean

was rich in natural resources and led to repeated invasions from the macedonians

encouraged greater contact with peoples on the southern and eastern mediterranean coasts

caused the greeks to eventually relocate eastward under alexander the great
