Mediterranean Sea

The Mediterranean Sea lies between Europe, Africa and Asia. Its name comes from Latin and means “in the middle of the land”, because land surrounds it almost completely.

Where is Mediterranean Sea?

Part of: Atlantic Ocean.

Countries on its coasts: Spain, France, Monaco, Italy, Malta, Slovenia, Croatia, Bosnia and Herzegovina, Montenegro, Albania, Greece, Türkiye, Cyprus, Syria, Lebanon, Israel, Egypt, Libya, Tunisia, Algeria, Morocco.

The story behind it

The Mediterranean is almost a closed sea. In the west, the Strait of Gibraltar is only 14 km wide and links it to the Atlantic Ocean. In the south-east, the Suez Canal, dug by people, leads to the Red Sea. The hot sun makes much more water evaporate than rivers and rain bring in, so the Mediterranean is saltier than the Atlantic. About six million years ago it almost dried up completely! About 5.3 million years ago the Atlantic poured back in and filled it again in less than two years. Today more than 17 000 kinds of sea creatures live here, from fin whales and dolphins to rare monk seals in the Aegean Sea off Greece. The biggest islands are Sicily and Sardinia, and port cities such as Naples, Alexandria and Trieste have traded by ship for thousands of years.

Questions children ask

How big is the Mediterranean Sea?

The Mediterranean Sea covers about 2.5 million km². At its deepest point, the Calypso Deep in the Ionian Sea, it goes down 5 109 m.

Why is the Mediterranean so salty?

In the warm sunshine, more water evaporates than rivers and rain bring in. The salt stays behind, so the water is saltier than in the Atlantic.

How is the Mediterranean connected to other seas?

The narrow Strait of Gibraltar links it to the Atlantic, and the Suez Canal links it to the Red Sea. In the north-east, the Dardanelles and the Bosporus lead to the Black Sea.
