Amazon River – The Eight Most Important Things to Know About the Amazon River

The Amazon River in South America is an amazing and important river for the planet and therefore, you need to know about it. Here are the eight most important things you need to know about the Amazon River:


The Rio Negro tributary of the Amazon River in Brazil.

1. The Amazon River carries more water than any other river in the world. In fact, the Amazon River is responsible for about one-fifth (twenty percent) of the fresh water that flows into the world’s oceans.

2. The Amazon River is the second longest river in the world (The Nile River in Africa is the longest) and is about 4,000 miles (6400 km) long. [In July 2007 a group of scientists reportedly determined that the Amazon River might just be the longest river in the world, taking that title from the Nile River. It will take further studies to substantiate the claim and for the Amazon River to be recognized as the longest.]

3. The Amazon River has the largest watershed (area of land that flows into the river) and more tributaries (streams that flow into it) than any other river in the world. The Amazon River has more than 200 tributaries.

4. Streams that begin in the Andes Mountains are the starting sources for the Amazon River.

5. Most of the run-off of Brazil flows into the Amazon River along with run-off from four other countries: Peru, Bolivia, Colombia, and Ecuador.

6. Due to the vast amount of water as well as sediment that are deposited where the Amazon River meets the Atlantic Ocean, the colour and salinity of the Atlantic Ocean are modified for nearly 200 miles (320 km) from the delta.

7. For much of its path, the Amazon River can be as much as one to six miles wide! During flood seasons, the Amazon River can be much, much wider; some report it is more than 20 miles wide (32 km) in certain places.

8. The Amazon River taken different routes since it began to carry water. Some scientists have determined that the Amazon River even flowed west at one time or more, into the Pacific Ocean.
