Aegean Sea

The two main seas surrounding Italy are the Adriatic Sea (on the eastern coast, represented in orange) which connects Italy with the Slavic countries, and the Tyrrhenian Sea (on the western coast of Italy represented in blue).

The name Ionian comes from the Greek language Ἰόνιον (πέλαγος). Its etymology is unknown. In ancient Greek the adjective Ionios (Ἰόνιος) was used as an epithet for the sea because Io swam across it. According to the Oxford Classical Dictionary, the name may derive from Ionians who sailed to the West.

Why is the Mediterranean so perfectly blue in colour? It is lacking in a number of nutrients that lead to plant growth in other seas and oceans (causing that more familiar green-brown colour that is so unattractive), and as such it retains its wonderful blue hue.

The Aegean Sea Plate (also called the Hellenic Plate or Aegean Plate) is a small tectonic plate located in the eastern Mediterranean Sea under southern Greece and far western Turkey….

For millions of years the African plate, which contains part of the Mediterranean seabed, has been moving northward toward the Eurasian Plate at a rate of about an inch every 2.5 years (a centimeter a year).

Because of the narrow connection to the Atlantic Ocean the tides in the Mediterranean are limited. The water in the Mediterranean Sea is slightly saltier than the Atlantic Ocean because of the narrow connection and evaporation.

From ancient times the Mediterranean Sea served as a great highway, linking the lands around its shores. It played an important role in the Roman Empire, in the rise of Italy’s maritime* cities, and in the expansion of the Islamic world across northern Africa to Spain.

Due to the high temperatures in the Mediterranean region, evaporation of the Mediterranean Sea occurs more rapidly than in other bodies of water, therefore more salt is left behind. The warm, dense, salty water in the Mediterranean is replaced by less salty and dense Atlantic water in the Strait of Gibraltar.

The Mediterranean nearly dried up. A cataclysmic flood revived it. The Mediterranean Sea’s only connection to the world’s oceans is through a narrow strip of water between Europe and Africa known as the Strait of Gibraltar, as shown here in a image taken from the International Space Station.

Ocean salt primarily comes from rocks on land and openings in the seafloor. Rocks on land are the major source of salts dissolved in seawater. Rainwater that falls on land is slightly acidic, so it erodes rocks. This releases ions that are carried away to streams and rivers that eventually feed into the ocean.

Salt is obtained from seawater by the process of Evaporation.

To separate salt from sea water evaporation is carried out. Evaporation is better method than crystallisation because it can be performed at the large scale with less cost in purification process and also the salt is obtained in more purified state than through crystallisation.

Desalination is a process that removes dissolved minerals (including but not limited to salt) from seawater, brackish water, or treated wastewater. A number of technologies have been developed for desalination, including reverse osmosis (RO), distillation, electrodialysis, and vacuum freezing.

You can use any piece of cloth—even the shirt on your back—or a non-poisonous grass mesh to slowly filter solid particles from your salt water. Catch the filtered water with a plastic bottle so you can better see if there are improvements in the clarity of your water.

Why can’t people drink sea water? Seawater is toxic to humans because your body is unable to get rid of the salt that comes from seawater. Your body’s kidneys normally remove excess salt by producing urine, but the body needs freshwater to dilute the salt in your body for the kidneys to work properly.
