Describe how sumer met the three criteria of a civilization. use specific examples

Surplus food —

After the Sumerians developed irrigation systems, they grew more wheat and barley than they needed at one time.

Division of labor —

Large teams of Sumerian workers cultivated the fields, and irrigated and harvested crops. Some continued to farm, but others became carpenters, metal-workers, potters, weavers, merchants, soldiers, doctors, etc.

Cities —

People clustered together in villages and towns to find work, sell their goods, store their grain, and bargain for food. Villages and towns grew into cities as more and more people came together. Ur, Uruk, Kish, Lagash, and Umma are examples of Sumerian cities.

Hi there, Sumer had writing system called cuneiform. Writing was very rare in Sumer because only boys from wealthy families could do it. One of the inventions Sumerians made was the wheel. They made the wheel because they needed something to help them carry heavy items to different places they traveled to. Their religion, sumerians are polythesists it means they believe or worship more than one god. They made zuggurats for their gods and always tried to make and keep their gods happy.
