Gulf of Suez
Where the Sinai Peninsula bifurcates the Red Sea, it divides the waterway into two distinct areas, the Gulf of Suez to the west and the Gulf of Aqaba to the east. The division began relatively recently in geological terms, about 28 million years ago with the formation of the Gulf of Suez Rift basin. Today the Gulf of Suez is about 300 kilometers (186 miles) long, terminating at Suez at the entrance of the Suez Canal. The midline of the gulf represents the boundary between Asia and Africa, and beneath its waters is a rich supply of oil and gas.
