The correct answer is Brazil, Colombia, Bolivia. These three countries are among the nine nations that are covered by the vast Amazon rainforest. The Amazon basin spans approximately 6.7 million square kilometers, with the majority of the rainforest located within Brazil's borders.
Understanding the Geographic Spread of the Amazon Rainforest
The Amazon rainforest is the world's largest tropical rainforest, covering a significant portion of the South American continent. The nine countries that share the Amazon basin are:
- Brazil – hosts the largest portion, approximately 60% of the entire rainforest.
- Peru – holds the second-largest share of the Amazon.
- Colombia – contains a substantial portion of the northwestern Amazon.
- Bolivia – covers the southwestern part of the basin.
- Ecuador – includes a small but ecologically significant area.
- Guyana – lies on the northern edge of the rainforest.
- Suriname – also located in the northeastern Amazon.
- French Guiana – an overseas department of France, located on the northeastern coast.
- Venezuela – includes the Amazonas state in its southern region.
The Amazon rainforest is often referred to as the "lungs of the Earth" because of its immense capacity to absorb carbon dioxide and produce oxygen. It is home to an unparalleled diversity of plant and animal species, many of which are found nowhere else on the planet. The river system, particularly the Amazon River itself, is the largest by volume of water in the world and plays a crucial role in the region's climate and ecology.
Why the Other Options Are Incorrect
- Indonesia, Cambodia, Malaysia: These countries are located in Southeast Asia. While they do contain tropical rainforests (such as the Borneo rainforest), these are not part of the Amazon basin, which is exclusively in South America.
- South Africa, Zambia, South Sudan: These countries are in Africa. The African continent has its own rainforests (such as the Congo Basin), but they are entirely separate from the Amazon. None of these countries are covered by the Amazon rainforest.
- Canada, Mexico, USA: These countries are in North America. While they have forests, including temperate rainforests like the Pacific Northwest, they are not part of the Amazon biome.
Therefore, the only correct answer is Brazil, Colombia, and Bolivia, as these are the three valid South American countries covered by the Amazon rainforest.
