Which ocean touches both South America and Africa?

The Atlantic Ocean touches both South America and Africa.

The Atlantic occupies an elongated, S-shaped basin between the Americas to the west and Europe and Africa to the east. Its southern section, the South Atlantic, directly separates the eastern coast of South America from the western coast of Africa.

This ocean took shape when the ancient supercontinent Gondwana began breaking apart during the Early Cretaceous. As the South American and African plates moved away from each other, new crust formed along the Mid-Atlantic Ridge, gradually widening the basin. The apparent fit between the two continental coastlines helped inspire early ideas about continental drift.

The Atlantic is the world's second-largest oceanic division and connects with the Arctic, Pacific, Indian, and Southern Oceans. A common mix-up is the Southern Ocean: it surrounds Antarctica and meets the Atlantic, but it does not directly touch both South America and Africa in the usual quiz-geography sense.
