Oceans' bottom is crossed by a huge mountain range, the oceanic ridge. Most of the time invisible, hidden by miles-deep dark waters, it is therefore our planet's

Major Geological Characteristic

With an average height of 4,900 yards above ocean's bottom - that means about Mont-Blanc height - this range is spreading all over the world, zigzagging between continents. It is about 44.000 miles long on an average width of 500 miles or so; that makes the earth's longest mountain range. But since it is under water, we normally don't pay attention. However it does deserve a careful attention,  for many incredible achievements happen years after years, well hidden under the sea.

Part of ridge may appear here and there, emerging its mountaintops: they make pelagic islands, that is to say open sea islands in the geology and navy language. Concerning the Atlantic Ridge, emerging tops are Azores IslandsOne of the locations mentionned fot Atlantis or Iceland.  A land of ice and fire with its glaciers and volcanoes, Iceland is the most significant example of oceanic ridge emerging. Its numerous volcanoes, like the one with a tricky name that is still poisoning european, american and african sky, are ridge's activity spots all right.

So researchers may observe the ridge without leaving dry land.

Key of Tectonic Plates, the ridge is the matrix where magma from the deep is added to existing crust. The further away from ridge, the older are the rocks. Like a travelator,  the ocean's bottom is constantly recycling. This curious phenomenon evokes a biological process, as snake's sloughing. Why wondering about earth's moulting ? Is it not a living being?See Barefoot French geologist Claude Allègre and other scientists have develop this theory called Tectonic Plates. And it was accepted very quickly by the word scientific community.

Continental Drift

Another consequence is: oceanic ridge's activity leads a phenomenon called continental drift. It started 250 million yearsMan was it on earth at that time? May be. See La vérité sur notre âge. ago, or even earlier. Before that process was on, all emerged lands formed an only continent called Pangea, that means the whole earth.  This monocentinental theory was imaginated by Alfred Wegener, who dated his Pangea 300 million years old.Some sighted persons think it is more recent. See La recherche du temps perdu As for Allègre's Tectonic Plates, today the Wegener's hypothesis has became a scientific truth.

And it clearly shows that geology is more dynamic and open-minded than archeology,See Antarctic 2016 which has became kind of a sect. At the end of this paper, we are enven more embarassed to locate Atlantis IslandSee L'Atlantide retrouvée as Plato seemed to do, right in the middle of Atlantic Ocean. The ridge growing for million years forbids a large island's presence. Probably we must pay more attention to the Plato's Timaeus, not only generally, but to the letter of the text.
