The Amazon Basin is a large area in South America drained by the Amazon River and its many tributaries. This basin is mostly in the tropical region, very close to the equator, which lies between 10° North and 10° South latitude. Because it's so close to the equator, this area is called the equatorial region.
The Amazon River flows from the mountains in the west towards the east and finally empties into the Atlantic Ocean. The function of a river’s mouth is where it flows into another body of water, such as an ocean.
The Amazon Basin covers parts of several countries, including Brazil, Peru, Bolivia, Ecuador, Colombia, and a small part of Venezuela.
Countries of the Amazon Basin through which the equator passes:
- Brazil – The equator passes through the northern part of Brazil, and much of the Amazon Basin lies in this country.
- Ecuador – As the name suggests, Ecuador is located on the equator, meaning the equator passes right through it, and part of the Amazon Basin lies here.
- Colombia – The equator crosses the southern part of Colombia, which is also part of the Amazon Basin.
So, the equator passes through the Amazon Basin in the countries of Brazil, Ecuador, and Colombia.
