Explanation

The Nile River, traditionally considered the longest river in the world at approximately 6,650 km, flows through northeastern Africa. However, this is debated - some measurements place the Amazon River as longer. The answer depends on measurement methodology and source selection. For most educational purposes, the Nile is accepted as longest, but recent studies suggest the Amazon may be longer.
