25 Longest Rivers In The World

Posted by , Updated on April 23, 2024

Interestingly, establishing the length of the world’s longest rivers has sparked extensive debate! Rivers are essential to our survival, facilitating commerce, agriculture and human livelihood. However, their accurate length estimation still poses a challenge and is mostly approximate. Over time, a notable dispute has arisen about whether the Amazon or the Nile takes the crown for the world’s longest river. We have compiled this list respecting the overall agreement among a majority of scientists. Therefore, we bring you the list of the 25 Longest Rivers In The World.
