Question

Which is the world’s largest drainage basin?

Answer 1

Hint: A basin is a depression in Earth’s surface which is usually shaped like a bowl. Some of them are empty while others have water. The largest drainage basin covers an area of 6300000 km and is located in the countries of Bolivia, Brazil, Colombia, Ecuador,(France), Guyana, Peru, Suriname, and Venezuela.

Complete Answer:
The Amazon basin is a large area of land which drains into the river of Amazon and its tributaries. The Amazon River is about 48 kilometers in terms of the span. Both the River and basin are abode to various kinds of flairs and fauna. It is estimated that one-fifth of all water on Earth is carried by the Amazon River. It has more than 1,100 tributaries, 17 of which are over 930 miles (1,497 km) long. Hence, it has the largest drainage system in the world.
According to the U.S. Geological Survey, it occupies about 38 percent of the total area of South America and covers a total of 2.67 million square miles. It’s lowlands to enrich the surrounding soil. Most of the basin and two-thirds of the river are located in the country of Brazil. Indigenous people include a population of 9 percent out of the total, including 350 different ethnic groups and more than 60 of those remaining essentially isolated.
Based on the aforementioned information, the correct answer is the Amazon Basin.

Note: A group of international scientists recently discovered a coral reef system in the river's plume, the area where the river empties into the ocean.
They are situated well below any incoming sunlight or a few hundred feet below the Amazon's turbid plume which is about 65 feet (20 m) thick.
