What is the name of the ocean on the East coast of South America?

The Atlantic Ocean is located on the east coast of South America, making it the correct answer. This ocean is the second-largest in the world and stretches from the Arctic Ocean in the north down to the Southern Ocean in the south, bordering numerous countries, including Brazil, Argentina, and others along the eastern coastline of South America. The Atlantic Ocean plays a crucial role in global trade and climate, and its waters significantly influence the weather patterns of the continent.

In contrast, the Indian Ocean lies to the southeast of Africa and between Africa and Australia, the Arctic Ocean is located to the north of the mainland Arctic regions, and the Pacific Ocean is situated on the western side of North and South America. Understanding the geographical positioning of these oceans helps to clarify why the Atlantic is specifically associated with the eastern coast of South America.
