Name the body of water that separates Saudi Arabia from Africa.

The body of water that separates Saudi Arabia from Africa is the Red Sea. This sea is a crucial geographical feature located between northeastern Africa and the Arabian Peninsula. It runs approximately 1,400 miles (2,300 kilometers) from the Gulf of Suez in the north to the Bab el Mandeb strait in the south, where it connects to the Gulf of Aden and the Arabian Sea.

The Red Sea has significant historical and economic importance, serving as a vital shipping route for trade between Europe and Asia. The waters of the Red Sea are also notable for their diverse marine life and coral reefs, making it a popular destination for tourism and scientific research.

The Persian Gulf, while located near Saudi Arabia, is situated to the east of the country and does not separate it from Africa. The Atlantic Ocean lies far to the west of both Saudi Arabia and Africa. The Arabian Sea is located to the south of the Arabian Peninsula, also not serving as a boundary between Saudi Arabia and Africa.
