Think of mountain creeks cascading into a lower pond, which then drains into a stream that might become a tributary flowing into a lake that spills its contents into a river that eventually reaches the ocean.
Each step of the way is lower in elevation than the previous one, but also closer to the center of the Earth. Either direction we care to go, if we travel a mile or 10, miles, we will still be influenced by the same universal gravitational field. The same holds true for the Nile or Mississippi River. It then flows 4, miles northward to its terminus in Alexandria, Egypt, at an elevation of 16 feet, or about 3, miles to the center of the Earth. The total decent from start to finish, 3, feet — slightly less than three-fourths of a mile with approximately 0.

Why does the Nile flow north from Lake Victoria into the Mediterranean? Michael L. Moravitz, Fairfax, Virginia. Besides using the river's natural resources for themselves and trading them with others, early Egyptians also used the river for bathing, drinking, recreation, and transportation.
Today, 95 percent of Egyptians live within a few kilometers of the Nile. Canals bring water from the Nile to irrigate farms and support cities. The Nile supports agriculture and fishing. The Nile also has served as an important transportation route for thousands of years.
However, the silt and sediment that used to flow north, enriching the soil and building the delta, is now building up behind the dam instead. Instead of growing in size through the soil deposits, the delta is now shrinking due to erosion along the Mediterranean Sea.
In addition, routine annual flooding no longer occurs along parts of the Nile. These floods were necessary to flush and clean the water of human and agricultural waste. As a result, the water is becoming more polluted. The Nile River also continues to be an important trade route, connecting Africa with markets in Europe and beyond.
