ABOUT GREECE | GEOLOGY
Greece is a mountainous country, 80%, only 20% is flat, while 60% of its mountains are over 2000m/6000f high. The highest mountain is Olympus (2917m/9000f) and the two largest plains are located in middle (the region of Thessaly) and north (the region of Macedonia) Greece. Deep gorges (the deepest in Europe), caves, lakes and rivers mould the country`s relief creating so diverse terrains which change so frequently.
The coastline is not monotonous at all, on the contrary. With a coastline of a total length that equals the length of the coastline of the whole continent of Africa, the choices among the baren kilometres/miles long sandy beaches, the small sandy or pebbly coves, pine forests and olive tree forests or tamaris trees on the beach, rocky coast for diving or fishing, white, golden, red, grey, black sand, are so many.
The largest part of the ground is sedimentary, but, as there is a volcanic arrow running through the country from NW to SE, there are a few volcanos, some of which are active, such as the famous island of Santorini.
