The Mediterranean Sea is an inland sea (from the Latin medius and land); is what remains of the vast and ancient sea Tethys, which in the Oligocene (about 30 million years ago) was compressed by the collision of two tectonic plates that still converge on each other determining the activity of the volcanoes Etna, Vesuvius, Stromboli and they cause earthquakes in Italy, Greece and Turkey.
The Mediterranean is between Europe, Asia and Africa and is connected to the Atlantic Ocean in the west via the Strait of Gibraltar; the Strait of the Dardanelles, the sea of Marmora and the Bosporus connect it to the Black Sea. To the southeast, through the Suez canal (opened during the 19th century) it is connected to the Red Sea and the Indian Ocean.
