A river bed is the bottom channel where water flows! The longest river in the world is the Nile at 4,135 miles, though some argue the Amazon is longer. Rivers have been essential to human civilization - most major cities were built near rivers for water, transportation, and trade. Rivers can carve through rock over millions of years to create canyons!
