Food, shelter, fertile land, and trade were essential for early river-valley civilizations. Without food, shelter, fertile land, and trade early river-valleys where doomed for any future success in the land. Egypt, Mesopotamia, and the Indus Valley are examples of some early river-valley civilizations that relied heavily on its geographies and Mother Nature.
For early river-valley civilizations in Egypt the Nile River played a crucial role. Without the Nile, Egypt would be a bleak and hospitable desert filled with mountains, and rocks. The Nile provided water for the people of Egypt. With the Nile being really the only source of water for all of Egypt, I would imagine that these civilizations cherished the Nile heavily. The Nile also, helped the farming in Egypt improve. Every September, the Nile, overflowed its banks, spreading water out into the bordering depressed basins. When the waters receded, they left behind a fertile layer of mineral-rich silt, and the farmers could easily plant their crops in the moist soil.
The early river-valley civilizations of Mesopotamia relied greatly on the Tigris, and the Euphrates Rivers. Mesopotamia means, "Land between the rivers."
Mesopotamian civilization developed in the plain alongside and between the Tigris and Euphrates, which originate in the mountains of eastern Anatolia and empty into the Persian Gulf. Without the rivers, the civilizations would have struggled greatly to survive. Reed plants, which grew on the riverbanks and in the marshy southern delta, could easily be woven into mats, baskets, huts, and boats. Also, fish from the rivers and marshes were an important part of the people's diet [http://search.targetwords.com/u.search?x=5977%7C1%7C%7C%7C%7Cdiet%7CAA1VDw]. Another benefit that the rivers gave to the early civilizations was that, herds of sheep, and goat which grazed on the fallow land provided...
