Question

Why do you think many cities in Mesopotamia developed near rivers?

Answer 1

River valleys not only have water, they also often have a broad, flat floodplain that is readily adapted to agriculture. Even the earliest, least sophisticated agricultural techniques would have been effective in yielding a significant bounty of crops from the naturally-irrigated and fertile soil of a river valley. :)

Answer 2

They developed near rivers because the rivers had silt (a type of fertilizer) to help there crops grow during their times. Also they would use the rivers to trade their goods with other cities in Mesopotamia.
