The document discusses how the Nile River contributed to the development of ancient Egypt civilization through agriculture, trade, travel, and technology. The river's predictable flooding provided fertile soil for agriculture. It also served as a transportation route for goods, services, and resources like gold, wood, and copper to be traded along its 4,160 mile length. Ancient Egyptians developed irrigation systems and tools like the shaduf to make use of the Nile's waters for hydro-powered technology and agriculture.
