According to the United States Geological Survey (USGS), the longest river in the world is traditionally considered to be the Nile River, which measures about 4,132 miles (6,650 km) in length
. However, there is scientific debate regarding whether the Amazon River might actually be longer. Some recent measurements suggest the Amazon could be longer by about 100 km, depending on the measurement methods and definitions of the river's source and mouth
. The USGS acknowledges the Amazon as the world's largest river by discharge volume, highlighting its immense size and significance
. In summary:
- The Nile River is officially recognized as the longest river in the world at approximately 4,132 miles
- The Amazon River is the largest by water discharge and may be longer than the Nile according to some recent studies, but this is still debated
Thus, the USGS generally lists the Nile as the longest river, with the Amazon as a close contender depending on measurement criteria.
