Which of the following is the world's widest river?
Flowing some 6,992 km (4,345 miles), one of the world’s longest rivers is also the widest.
At its thinnest section, the Amazon stretches a “mere” 1 km (0.62 miles) across. However, on average the Amazon is quite a bit wider - between 3.2 to 8 km (2 to 5 miles) wide - and that is just during the dry season. The wet season sees the river grow substantially, to a width of up to 100 km (62 miles) in some areas.
Just for comparison, the Nile is about 6,650 km (4,130 miles) long, with a maximum width of 2.8 km (1.7 miles) at its widest point.
The Yangtze is the longest river in both China and Asia, and third longest river in the world, at 6,300 km (3,900 miles) long. Although it is extremely deep in places, the width varies, from 30 meters (98 feet) at its narrowest point to 650 meters (2,130 feet) at its widest.
At its source the “Mighty Mississippi” is only 6-9 meters (20-30 feet) wide, while at the widest point, Lake Winnibigoshish, the river sprawls some 17 km (11 miles) wide.
As if being (disputably) the longest and (definitely) the widest river were not enough, the Amazon is also the world’s largest river by volume.
