An isthmus
The largest isthmus in Central Africa is the Isthmus of Zaire, which connects the main body of the African continent to the enclave of Cabinda, an exclave of Angola. It is a narrow strip of land that separates the Democratic Republic of the Congo from the Atlantic Ocean.
The geographical formation that separates the Americas is the Isthmus of Panama. This narrow strip of land connects North America and South America, forming a natural barrier between the Atlantic and Pacific Oceans. The Panama Canal, constructed through the isthmus, allows ships to traverse between the two oceans, significantly facilitating maritime trade.
The Isthmus that connects Europe and Asia is the Turkish Straits, which include the Bosporus, the Sea of Marmara, and the Dardanelles. These waterways divide the continents of Europe and Asia in Turkey.
