Hello, I want to learn about Mesopotamia.
Sure. Are you interested in the geography?
Of course, please tell me about the geography of Mesopotamia.
Mesopotamia is located between the rivers Tigris and Euphrates. Both have their head waters in the the Taurus mountains.
Good to know. can you tell me something else about the geography of that place?
Irrigation in Mesopotamia is helped by the high water table and by melting snow from the high peaks of the northern Zagros Mountains and Armenian Highlands
Some other fact that you want to add about geography?
It's a historic region in the middle east. It now includes most of today's Iraq, and parts of modern day Syria, Turkey, and Iran.
What about the economy and agriculture?
Over time the most southern parts of Sumerian Mesopotamia suffered from increased salinity of the soils. This actually lead to slow urban decline and centering the powers of Akkad further north.
Interesting, please tell me more about this.
The Euphrates was important for the establishment of major cities such as Ur and Uruk, which took root on its tributaries. Others, like Lagash, were built on the branches of the Tirgris.
Thank you very much for you time. All this information was very helpful. I learned a lot.
Happy to help!
