List of 20 Longest Rivers in the World


Rivers have been a source of water for human lives. The first human civilizations were all near a river as these provided humans with water. With the advent of technology, water transport systems have developed and we no longer need to settle on the river banks. Rivers have now become a lot more than just sources of water. They have become recreational spots, being hosts to many activities such as kayaking, boating, and fishing.

The topic of the longest river in the world has been a much-debated issue for the past two decades. The technique of the length measurements varies from one group to another, and therefore we have a range of lengths in which the river’s length lies. Also taken into consideration is the furthest water source which drains into the river. Therefore, it is a much-debated topic.

In 2007, scientists on an expedition discovered that Amazon was much longer than the Nile, which made Amazon the longest river in the world. In 2009, a study published in the International Journal of Digital Earth showed that the Nile is much longer than the length it was previously measured, and if this length is taken into account, Nile remains the longest.

In this list of rivers, we have taken the longest lengths of the rivers from all the lengths provided. Happy Reading and Discovering some facts about the longest water bodies in the world.
