Which strait separates the European and African continents at the western entrance to the Mediterranean Sea?

The Strait of Gibraltar separates Europe and Africa at the western entrance to the Mediterranean Sea.

It lies between southern Spain and northern Morocco, connecting the Atlantic Ocean with the Mediterranean Sea. At its narrowest point, the strait is about 14 kilometres wide. The Rock of Gibraltar rises on its northern side and gives the waterway its modern name.

The strait is strategically important because ships using the Atlantic–Mediterranean route pass through it. It also forms a major boundary between different water masses and has strong currents. During the last ice age, lower sea levels may have restricted or temporarily interrupted the connection between the Atlantic and Mediterranean, but today the strait is a permanent maritime passage.
