Which of the following river basins is the largest in the world by total water discharge and drains the extensive tropical rainforests of South America?

💡 Solution & Explanation

The Amazon River basin in South America covers an immense area of tropical rainforest and discharges more water into the Atlantic Ocean than the next seven largest rivers combined. The Nile is renowned as the longest river in geographical length, flowing through northeastern Africa into the Mediterranean Sea. The Congo River drains central African rainforests with the second-highest discharge volume, while the Mississippi-Missouri system drains central North America. Tropical drainage basins are vital regulators of global hydrological cycles and carbon sequestration.
