The River Nile

AFRICA

The River Nile is about 6,670 km (4,160 miles) in length and is the longest river in Africa and in the world. Although it is generally associated with Egypt, only 22% of the Nile’s course runs through Egypt.

In Egypt, the River Nile creates a fertile green valley across the desert. It was by the banks of the river that one of the oldest civilizations in the world began. The ancient Egyptians lived and farmed along the Nile, using the soil to produce food for themselves and their animals.

How many rivers of the world can YOU recognize?

Rivers That Flow North - http://www.worldatlas.com/aatlas/infopage/riversno.htm

(actually downhill) in a northerly direction 

THE FACTS: Unless the land it totally flat, rivers of water run downhill. The vast percentage of rivers on the planet flow in a southerly direction because the source (usually in the mountains) is to the north of the mouth.

If the source of a river is at a higher elevation than the mouth, that river will run from the source to the mouth. However, if that (higher) source is to the south of the mouth, that river will then flow to the north (downhill).

Below is a partial list of rivers (length listed when known) that do just that. We haven't listed rivers that run to the northwest, or rivers that don't meet the exact requirements
