Which ocean borders Africa to the south?

The Indian Ocean borders Africa to the south, making it the correct choice for this question. This ocean is notable for its warm waters and is the third-largest ocean, covering a significant area of the Earth's surface. It plays a vital role in maritime trade and has a diverse ecosystem that includes rich marine life and coral reefs.

In geographical terms, the Indian Ocean lies between Africa on the west and Australia on the east, and it extends down to the Southern Ocean, which surrounds Antarctica. Its significance also lies in its economic implications for the countries along its coasts, which often engage in fishing, shipping, and tourism.

While the Atlantic Ocean does border the western part of Africa, it does not extend to the southern tip of the continent. The Pacific Ocean, primarily located to the east of Asia and Australia, is far removed from Africa, and the Arctic Ocean is situated at the northern polar region, also irrelevant to Africa's southern border. Therefore, the Indian Ocean is indeed the correct ocean that borders Africa to the south.
