What is the deepest river in the world?

• A. Nile River
• B. Congo River
• C. Amazon River
• D. Yangtze River

Answer: (B)

Deepest refers to how far the riverbed lies below the water surface. The Congo River in Central Africa has the deepest measured points, with the channel reaching roughly 200–220 meters (about 650–720 feet) below the surface in places. This great depth comes from the basin’s geologic setting and the river’s long, powerful erosion, which has carved a very deep, steep-walled channel over time. Other large rivers—like the Nile, Amazon, and Yangtze—can be very deep too, but their maximum depths are generally shallower than the Congo in most sections, often well under 120 meters. So, the Congo River stands out because its deepest sections are deeper than those of the others, making it the deepest river in widely cited measurements.
