Which Of The Following Bodies Of Water Are Identified Correctly On The Map Above I Number 3 Is The Amazon River II Number 6 Is The Atlantic Ocean III Number 7 Is The Pacific Ocean?
The Amazon River is one of the most recognizable natural features on Earth. At 4,345 miles long, it's often called the second-longest river in the world after the Nile—though measurement methods still spark debates. Its drainage basin covers about 2.7 million square miles across nine South American countries. Where it meets the Atlantic Ocean, you'll find its mouth at coordinates 0.0000° N, 50.0000° W in northern Brazil.
Quick Fact
The Amazon River stretches 4,345 miles and empties into the Atlantic Ocean at 0.0000° N, 50.0000° W. Its mouth stretches 240 miles wide—making it the widest on Earth as of 2026.
Which bodies of water are correctly identified on the map?
Number 3 is the Amazon River, number 6 is the Atlantic Ocean, and number 7 is the Pacific Ocean.
Geographic Context
This river cuts through the Amazon Rainforest, the largest tropical rainforest globally. The ecosystem spans Brazil, Peru, Colombia, and six other South American countries. The river isn't just water—it's a lifeline for biodiversity and millions of people. Indigenous communities, cities like Manaus, and even global climate patterns depend on it. The basin produces about 20% of the world's oxygen and locks away massive amounts of carbon.

Why is the Amazon River so ecologically important?
The Amazon supports unmatched biodiversity and produces about 20% of the world's oxygen.
Interesting Background
Near Manaus, you can see the “meeting of the waters” where the dark Rio Negro flows alongside the sandy Amazon for about 6 miles without mixing. The river's home to anacondas, pink river dolphins, and over 3,000 fish species. Indigenous groups like the Yanomami have lived along its banks for millennia. Fun fact: Spanish explorer Francisco de Orellana named it in 1541 after claiming female warriors attacked him—comparing them to the Amazons of Greek myth.
Can you visit the Amazon River? What should travelers know?
Yes, but access is mainly by riverboat or small aircraft, with Manaus, Iquitos (Peru), and Leticia (Colombia) as primary gateways.
Practical Information
As of 2026, getting to the Amazon means taking riverboats or small planes. Manaus, Iquitos, and Leticia serve as the main entry points. Here's the thing: water levels change dramatically by season. Floods peak from May to July, while October droughts can leave boats stranded. Swimming in the main river isn't recommended—strong currents and parasites make it risky—but calmer tributaries are safer. The river fuels local economies through fishing and eco-tourism, with guided jungle tours often highlighting conservation work by groups like the National Geographic Society and IUCN.
How do the Amazon, Atlantic, and Pacific compare on a map?
