Answer:
Mesopotamia means "land between rivers". It receives this name because it's located between the rivers Tigris and Euphrates, which comes from the mountains and run down in the Persian Gulf. This location is also known as Fertile Crescent.
Step-by-step explanation:
Agriculture was the main economic activity of the region, especially the cultivation of barley, wheat, and vegetables. Water supply for the development of these activities required a great collective effort. The work of controlling the Tigris and Euphrates floods and the construction of a complex irrigation system was fundamental for the survival of the settlements.
