Do rivers always flow from the north to the south?While some oblivious people think that rivers always flow from the north to the south (a term some even call downhill!) but rivers always flow with gravity (unless modified by humans). There are countless examples of rivers that flow from the south to the north (in both hemispheres), such as the Ob in Russia and the Mackenzie in Canada.
An interesting analogy was brough up in the Geography Forum - would you fly to Seattle, rent a car, and coast all the way to Los Angeles? Just because south is at the bottom of the map, doesn't mean it's lower in elevation.
