Post-Ice Age Flooding: Mediterranean and Black Seas

you would like robert samast`s theory

Wrong, the Med was flooded about 5 milion years ago. There are some who say it was then resealed and flooded again 34.000 years ago, but that IMHO is crock.

Another theory comes to mind when considering the knowledge of plate tectonics and the changes it might've brought to the geography of this planet over the period of millions of years.   There used to be a similar body of water known to modern geologists as Tethys.   At least until after the era following the great extinction of the dinosaurs, this larger sea existed where much of the Sahara Desert now exists and included what is now the Mediterranean and the Indian Ocean, which was but part of a even broader ocean at the time.  Then the continents began to drift into their current positions, and the sea floor which became northern Africa elevated until it became exposed.  Evidence of the ancient Tethys's existence is borne out by fossils of ancestors of the modern whale and porpoise dug out of the Sahara in Egypt, as well as a fish-eating dinosaur found in even older rocks in Algeria.  Some have seen the Mediterranean as being a remnant of that ancient sea now open to the oceans by that narrow strait in the west.

And yet, the whale and dinosaur fossils were found in the interior of north Africa, far from the shores of the Mediterranean.  As the sea level has also risen and fallen dramatically over periods of several millions of years, parts of the continents were submerged at one time or another.  During the last Ice Age, the floors of the Bering Sea, the English Channel and much of the sea bed surrounding the Indonesian archepelago were exposed.  Geologists are finding evidence of the Arctic Sea being landlocked and being mostly freshwater 55 million years ago during a period of warm temperatures which promoted the growth of water lilies there.  Only 15 million years before then, an inland sea existed on North America where the states of Texas, Oklahoma and Louisiana are today.

In fact, much of the continents as we know them today might have originally been undersea bedrock laid down by the same volcanic activity which continues around today's rift zones.   These are among the oldest rocks, often found at continental "cores" such as northern Canada and Siberia.  In the Himilayas, the impact of the Indian subcontinental plate literally squeezed oceanic bedrock upwards as part of the mountain range.  Ultimately, the processes of volcanism, erosion and sedimentation have added to the continent-building process, giving us the sizable landlmasses that we know in the present day.
