Question

which is the longest river in the world

Answer 1

The Nile in Africa has long been considered the world's longest river, but there is some debate about the definition of the length of a river that leads some to claim that the Amazon in South America is longer.

The claim that the Amazon is longer is reached by measuring the river plus the adjacent Pará estuary and the longest connecting tidal canal.

The approximate length of the rivers with the debated measurements are:

Nile: 4,132 miles, or other sources cite: 4,258 miles

Answer 2

Nile river is the longest river in the world
