Q. What Is the Longest River in the World?
c. Missi pissi
The Nile was usually said to be the longest river in the world, with a length of about 6,650 km, and the Amazon was the second longest, with a length of at least 6,400 km. In recent decades debate has intensified over the true source and therefore the length of the Amazon River. Brazilian and Peruvian Studies in 2007 and 2008 added the waterway from the Amazon’s southern outlet through tidal canals and the Pará estuary of the Tocantins and then concluded that the Amazon has a length of 6,992 km and was longer than the Nile, whose length was calculated as 6,853 km. However, as of 2010 the length of both rivers remains open to interpretation and continued debate.
