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

The ocean located on the West coast of South America is the Pacific Ocean. This vast body of water is the largest and deepest ocean on Earth, extending from the Arctic Ocean in the north to the Southern Ocean in the south. Countries like Peru, Chile, and Ecuador all have coastlines along the Pacific, which plays a significant role in their climate and marine biodiversity.

The other oceans mentioned do not border South America on the West coast. The Indian Ocean lies to the east of Africa and to the south of Asia, while the Arctic Ocean is situated around the North Polar region and far removed from the Pacific shores of South America. The Atlantic Ocean, although it borders the eastern coast of South America, does not affect the western coastline where the Pacific Ocean is found. Therefore, the correct identification of the Pacific Ocean accurately represents the geography of South America.
