Geographical location, natural conditions and population of Mesopotamia

“Mesopotamia” (“land between rivers”) is located in the valley of the lower reaches of the Tigris and Euphrates rivers.
As a result of the flooding of rivers, the plain turned into fertile soil (alluvial silt), then into a swamp.
Summer lasted 6 months (t + 52 ° С).
Disadvantages of natural conditions: lack of stone, wood and metal.
However, using waterways already in the 4th millennium BC, the Sumerians for the purchase of resources paved trade routes in the Middle East (Turkey, Egypt, Syria).
