Settings of Early Civilizations
The three settings or environments in which early civilizations developed were b. Rivers, valleys, and coastal areas. These locations provided fertile soil for agriculture, stable water sources, and other resources needed for sustaining large, settled populations and developing cultures. Early societies like those in ancient Mesopotamia and Egypt flourished along major river valleys such as the Nile and the Tigris and Euphrates. The access to fertile lands led to agricultural surpluses, which in turn allowed the specialization of labor and the formation of complex social structures.
Settlements like Jericho and Uruk in Mesopotamia are examples of early urban centers. The advancement in technology, agriculture, and organized governance in these areas laid the foundation for future development. It is in these environments that we see the rise of significant human civilization, market by the appearance of written languages, the building of elaborate structures, and the establishment of distinct cultures.
