geography

The structural formation of Greece reveals a young relief, formed in the Alpine orogeny, and abundance of limestone karst and subsequent relief. The general set descends from west to east, where the structures are immersed in the sea, leaving only the peaks emerged, forming the countless islands. The proximity to faults that separate the plates African, Eurasian and Arabian makes the region prone to earthquakes and volcanoes. The folded and fractured system, framed by faults is very complex. Fault lines into the sea, and the high block and sunken island status are responsible for much of the country. This fragmentation occurs in multiple directions, however, highlights a dominant structural direction from northwest to southeast, which is marked by mountains Olympus, Pindus and its extension in the Peloponnese.Regarding the geological substrate can differentiate two blocks, each consisting of metamorphic rocks northeastern, old and stiff, fractured by the Alpine orogeny and wherein lies the Rhodope massif, the region of Thrace and Macedonia. This set is completed with some metamorphic southern islands. The rest of the country is mostly limestone fold assembly. He is responsible for the numerous coves along the coast Hellenic cliff and character of much of the coastline.The character cut from the coast, and the many islands that individualize infinite sets in the interior gives a stamp eminently marine Greece. All within the Mediterranean Sea, we can distinguish four seas, the Ionian, the Aegean, Thrace and Crete.The main gulfs in Greece are: the Gulf of Thessaloniki, the Corinthian Gulf, the Gulf of Patras, the Strymonas Gulf, the Gulf of Volos, and the Gulf of Evia
