Fascinating fact: They reckon the very rapid drying of the Med left the Nile "hanging" with rapids or even a waterfall where it met the Med, and the much more rapid waters cut a deep canyon which moved south into Egypt in only a few millennia. When the Med filled again and the Nile slowed, that canyon quickly filled with the sediment that the Nile is famous for. If you look at the Nile Valley in northern Egypt today, you see that much of it is a flat, fertile floodplain with a rocky "lip" on each side before transitioning almost immediately into desert. Some reckon the relatively small cliffs that make that lip are in fact the top of a pair of canyon walls that would dwarf the Grand Canyon.....
One of the Cosmos episode explains how the Mediterranean Sea being refilled played a big part in the evolution of humans. The Mediterranean sea filling lowered the ocean level so that North and South America connected. This new connection shifted the ocean flow which make Africa much hotter and less of a forest. African primates in trees who'd become humans lost a lot of forest density to protect themselves from predators, and subsequently had to adapt to walk and run and use their hands for holding and using tools as weapons instead of hiding. Pretty fascinating.
I think this is a bit of an oversimplification. I don't remember Cosmos saying this specifically but if they did they are overselling (they did this a lot to ease story flow from one topic to the next). The Mediterranean closed about 5.9 million years ago and reopened about 5.3 million years ago. The closing of Americas took much longer, the South American plate beginning to subduct under North America about 24 million years ago and forming one contiguous land mass about 3 million years ago. The thing that disputes the 'Cosmos theory' is forests in East Africa began to be replaced by grassland about 10 million years ago and had switched completely around 3 million years ago. Another is that current scientific belief is the water transfer between the Pacific and Atlantic stopped between 7-11 million years ago, long before the Mediterranean closed and reopened. I do think it is accurate to say both events had various effects which in turn affected us. It seems likely to me that the linking of North/South America was the root cause for the formation of the African grasslands as it fits the timeline. It would be another 4 million years before the Mediterranean closed. I'm sure the closing of the Mediterranean 5.9 million years ago had its own effect as local heat patterns, blowing dust, and salinity and certainly would have changed climate all over the world. However, the forests in East Africa had already started disappearing long before this happened. Frankly, it is probably a good thing the grasslands took millions of years to appear. If it took less time humans would have been less able to adjust the new environment. At the very least, we would have evolved differently.
@Adam Vanderhoofven: All you've managed to do here is to prove -- 1) that you have no earthly clue how the processes of biological evolution work, and 2) that you have no clue what sort of fossil evidence for primate evolution actually exists. All in all, good job looking like a completely ignorant @55clown.
@lmb nasri: No one said that the primates in question "suddenly became incapable of climbing trees." The steady reduction in tree coverage reduced the protective advantage provided by the trees. Long-term survival in that context required adaptation. At least one, perhaps more, groups of these primates did adapt to a different preferred form of locomotion. Others probably did not (meaning they either died out or they adapted in some other way, leading to a different species line). See what happens when you actually do "switch on your brain" instead of just shooting your mouth off?

It would be great to do a video and description of the changing shoreline starting at the end of the last ice age and mapping out how the shoreline moved "inland" as the ocean levels rose from the ice melting. Now that would be interesting and would explain how so many ruins of towns and cities are now under water.
Did the Mediterranean Sea dry up because of an ice age? This would explain why ocean levels were lower at that time. As the polar regions melted, ocean levels would rise and eventually, the area between what is now Spain and Gibraltar would flood.
The one way for that to happen, I.E. dropping sea level is by having a freezing period where more water gets lock up in ice again. Aka another Ice Age.

There was a proposed geoengineering project a few decades back to build a gibralter damn to create a large energy supply plus tons of new land in the mediterranean. It was abandoned for several reasons. First, the massive terraforming would have changed the envoronment of a great deal of the world in ways that were not always predictable and often would have been disasterous, like the massively higher water levels flooding every coastal city on the world's oceans. And also because there wasn't enough concrete in the world to actually build it nor the technology to get it done. Plus, if it broke, everyone would die. So it was kind of a bad idea.
Stuff like this was the most interesting part of my Geology 101 class at university. Rocks for jocks! Or in my case science for a liberal arts degree.

Strangely, the video omitted mentioning the feedback that the desiccation of the Mediterranean Sea would have created beyond stating the quick drop in sea level when what we today call 'Gibraltar' opened up to flood the Mediterranean basin. When the Mediterranean dried up not only did all that water get redistributed to the rest of the world but it captured huge volumes of salt, making the world's oceans less salty. This could've led to an increase of ice buildup in the oceans and create surfaces reflecting more incoming sun light which in turn could lower temperatures and create major climatic changes to include ice age conditions. The amount of salt deposits around the Mediterranean indicates that there may have been multiple drying and flooding of the the Mediterranean basin. This whole picture hints at how the development of human populations and civilizations managed to squeeze itself between geological changes in the dynamic history of the planet. And that our fragile existence can't be taken for granted, especially if we ignore our own impact.
Imagine what kinds of life forms lived in the basin before Gibraltar opened back up. We could be on the surface of a series of great scientific discoveries. There could be creatures similar to that of the Atacama Desert in Chile, which is the current driest place on Earth. There could be so much buried down there, albeit the amount of fossils would be slim, due to likely not having the best conditions for fossilization, they it is possible, we have fossils from the Gobi Desert, and pretty good ones at that.
Hunting fossils would be extremely difficult. Remember that the inrushing Atlantic filled the Med in (at most) a couple of years...so we are talking water flows of trillions of gallons per hour. This would have scoured the surface away and dumped debris into the deepest portions where it might have had a chance to settle to the bottom over time. Any fossils that did survive being pulverised, would now be in the deepest parts of the Med...and under thousands of feet of silt. Now as for the gold and other treasures...it would include Roman, Greek, Egyptian cultural trophies among many others. So...who's got a boat? :-)
Cataclysmic inundations are ALWAYS "game changers"! Thank you for this marvelous compendium that succinctly explains what has been ambiguously told, before. The story of this "Middle Earth" Sea warrants attention by those who are tethered to Jedeo-Christian explanations on the origins of Western Civilization, if not humanity itself. Ditto, the Black Sea's inundation, at Bosporus. That recent catastrophe was dramatized by two scientists who wrote "Noah's Flood"; Bob Ballard (of Titanic fame) subsequently searched that Sea's bottom, and found nothing resembling ancient human habitats, however.
There's such an enormous current lowing through the Straits of Gibraltar that it would make a wonderful electricity generation project, and you could have a railway bridge across, linking Europe with Africa.
I've often wondered if Gibraltar breaking contributed to the legend of the Flood, but if it happened 5.5 million years ago there would have been no humans around to witness it.
A more likely candidate is the Black Sea flooding that occurred when sea levels began to rise after the last ice age. It is estimated that sea levels dropped about 130 meters at the last glacial maximum which is a problem when you consider the shallowest part of the Bosporus (which links the Black Sea to the Mediterranean) is about 13 meters deep. The rivers feeding the Black Sea don't have enough flow to fill that body of water completely so during the ice age it would have shrunk to about half its current size. At some point, estimated to be about 10,000 years ago, the waters of the Mediterranean sea rose enough to again top the Bosporus and its waters flooded the Black Sea. Scientists argue how quickly it filled but there is no doubt that whole communities were flooded and cultures had to relocate. Considering that the area north of the Caspian and Black sea is also a probable source of Indo-European language it it isn't too much of a leap of faith to link this event to the many of the stories as its people moved beyond this area. en.wikipedia.org/wiki/Black_Sea_deluge_hypothesis en.wikipedia.org/wiki/Indo-European_languages#Evolution
Agreed. The timing of the Black Sea flooding makes it much more likely, but the sheer scale of the Mediterranean has always fascinated me, so I guess it was some wishful thinking on my part.
First watch, i liked the pacing and delivery of the content, and the content itself. I got interested from fall of civ talking about the zanclean floods
535M years ago, a camera enthusiast was standing close to the Strait of gibraltar, when he saw a flood gate of water rush into the dry bed of mediterranean sea and he started filming. Indeed it was once in a lifetime opportunety.
And there is evidence that in HISTORICAL times (like flooded coastlines containing evidence of ancient civilization) that a similar event happened in which the Mediterranean itself broke through a land bridge in the Bosporous and flooded the basin of the Black Sea (which previously was probably a large freshwater lake.)
@Thomas Headley Shipwreck in the underworld and dinosaur somebody here for ghost sea Hunter is nightmarish the living creatures on the earth was kind of extinct things that island about fossils and bones at the field museum
Fascinating. I bet if there were any civilisations of any description around 5.3 million years ago, those in charge would be blaming the sins of the peasants for the change to what they were used to and demanding they mend their ways.
A lot of this is speculation. Ive heard it described differently in several places. It's possible the Mediterranean basin was habitable. Remember, the Sahara has undergone shifts in climate as well - frequently greening with abundant rivers that might also have fed the basin.
there's an interesting theory that states that this flood is what caused the mythos of the biblical flood. early humans experienced this and it morphed and changed as stories of it were told through the generations
At least two similar events have occurred in human history. The breaking of Niagara10,000 BC (coincidentally the beginning of the Neolithic Era) and the Bosporus around 6,000 BC. In fact, there have been archaeological dives in the Black Sea to underwater civilizations for many years.
During the glaciations the Mediterranean opened and closed many times, not because of tectonics, but because raise and fall of sea levels. The last one might have occured 10k-12k years ago.
fun fact gibraltar derived from the arabic word "jabal tarik" which literally translates to the mountain of tarik referring to the muslim umayyad general tarik ibin ziyad who conqured spain in 8th centuary and formed andalus
Maybe we would, but our culture would look different, or even not at all. The Mediterranean sea is the cradle of our western civilization. Not only that most civs lived alongside the shore but euphrat and tigris are also (partly) fed by evaporated water from the sea With that gone no civs would have formed alongside the Mediterranean, maybe only egyptian, but that would be isolated as no other civ would have formed around it in a desert bigger than the Gobi. Migration routs would have shifted, maybe we would never have left africa....and formed no civilization at all as all plants and animals used (most) came from eurasia and not africa The impact of that would have changed our evolution completely because it would have had effects on the climate in africa as well
Something like that happened to the inland sea of USA. That sea poured into the Snake River. in I have been there. It was road trip to Wyoming where and it has a rest stop there.
The continents are shifting a little today. To clarify, because we know this is happening constantly, we are witnessing the exact point of slight continental shift. Geological activity has increased in the pacific ocean recently. This has caused islands to raise and volcanoes to erupt. It's not over yet. Keep watching. Stay tuned and watch what happens next.
Thank you for you very informative and well presented video. I am not sure about one thing you said. What was the mechanism that reduced the salinity of the rest of the oceans when the catastrophic refilling of the Mediterranean basin happened?
Let's talk about Snowball Earth. If the entire world was covered in ice and snow, where did all the water which formed the ice and snow come from, and where had it gone? I mean If the ice sheet was thick enough to cover the tallest mountains, granted Mt. Everest hasn't been formed yet, there must be a hell of a lot more water on earth than there is now!!
I would leave a like if youtube wouldn't create a pointless playlist of my liked videos which I do not want, or if at least there would be an option to delete it.
The Mediterranian was populated by species from the relatively cooler Atlantic. Since there is the Suez Canal, other species from warmer seas have the opportunity to enter the Mediterranean Sea. Because they are better adapted to the warm water, they are more successful, especially since the Mediterranean is getting warmer, too, because of climate change. This would not be such a big problem was it not for the irrigation water taken from the Nile. Back when the Nile had enough water, it laid a sweetwater curtain around its delta which also covered the northern end of the Suez Canal keeping back the invasive species. But meanwhile so much water from the Nile is taken for irrigation that not enough sweet water reaches the Mediterranean to keep up the curtain effect to shield the Mediterranean from invasive species immigrating through the Canal.
In the deep parts would be like the Petronus towers standing with 3 more top of each other. Did not realise some parts in the Mediterranean sea got that deep wow .
4:21 it would be fun to know what could live there. It's about as extreme as Antarctica just the other way around. A super hot basin several km bellow sea level. I wonder how the air pressure affected birds. What kind of weather anomalies would it have? How would it's "shore" be?
Because the Med dried for so long it took a lot of salt out of the Earth's seas permanently. Much of that salt is burred under sand and rock deep below the water. The changes in salinity have interesting consequences for the ocean's, their ice formation, and sea life.
I did calculations. For ocean water bringing the Mediterranean Sea level back to normal... for that to had caused the global sea level to lower by 10 meters, the Mediterranean Sea level would only had risen by 1,924 ft. 3,000 ft shallower than the average depth of the Mediterranean Sea. So for that to had happened, the average depth of the shallower Mediterranean Sea before the spill, was 3,000 ft. Then the remaining 1,924 ft increase in the Mediterranean Sea level by the spill would had lowered the global sea level by 10 meters. By the way, if all the Mediterranean were evaporated, not including the Black Sea and Sea of Marmara, the global sea level would be 1,000 ft higher. Or 1,002.7 ft to be exact, based on my calculations from other measurements I found @ Google.
I don't believe your calculations are reliable. Just think - what is the ratio of Mediterranean Sea area to all of the oceans? I find just under 1 million square miles vs. 138 million square miles, so a change in Mediterranean level would be 138 times the greater ocean level change. 10m = 34' +-, 34 X 138 = 4692'. Pretty much what was claimed.
I can't see how the salinity of the rest of the world oceans would decrease with the re-formation of the Med (6:07). I would have thought, if anything, salinity would go up, due to the re-dissolving of the salts that remained in the dry Med basin from previous sea water. When the "old" Med dried up, the salinity of the rest of the world's oceans, it seems to me, would go down as the Med's water evaporated, because the water that came out of the Med would fall as rainwater in the oceans... Thefore diluting it. The overall water volume on the planet would roughly be the same, but the level of dissolved salt changes, depending on the existence, or not of the Med. I am no expert (in anything), can someone please explain. Thanks.
Good information but, your background music is in the foreground making it had to hear for those of us with hearing impairments. It would be a boon if your audio editor kept that in mind for future videos. Thanks. Keep up the good work.
If we were to build a hydroelectric dam at the Gibraltar and another at the Suez Canal and then allow the Mediterranean Sea to evaporate only a little, like 5-10 cm or even less : we would have so much electric energy !
this is going to be a dumb question, but lets say the earth closes the strait again and it starts to dry the Mediterranean. do you think humanity will realize the consequences and try to open it, and if so how much effort would that actually take without really screwing up nature?
It is somewhat of a 'dumb question' (..well you said it...lol). This video upload is an excellent explanation of how the Med was formed. And to give 'ZorakGoesOn' his dues, he did say that no-one really knows how the tectonics will 'pan-out'. But here is the current theory (via computer modelling of the ongoing global tectonic shift): As Zorak mentioned, the African plate continues to subduct (push beneath) the Anatolian and Eurasian plates. The Alps are therefor still being thrust up (a process known as 'orogeny' - or crust deformation - mountain building). Eventually the Mediterranean will be effectively narrowed until it becomes a narrow sea-way and eventually close altogether. the Atlas mountains (Northern Africa) will eventually 'meld' with the Alps. But that is not all... The Indian plate and the Indian sub-continent is also continuing to thrust northwards, in so doing, continuing the Himalayan orogeny. Deformation of the crust along these fault lines will cause a massive chain of mountains ranging from The Iberian peninsular (Spain) to roughly Sichuan in Western China. The Australasian and Antarctic plates are also continuing to march roughly north-eastward and will close up the Island chain of Indonesia/Sumatra/Borneo/ Philippines, in so doing closing the eastern Indian Ocean, which will become a vast inland sea. Bigger than the current Med. Now in the Atlantic, which is currently regarded as a 'constructive plate margin' is widening; that is to say, it is creating land along the mid-Atlantic ridge. However, the Pacific plate, the largest and most powerful plate on the earth's crust, is subducting beneath the North/South American plates. This action is what has formed the Coastal, Rockies and Andes mountain ranges. With the ongoing tectonic action creating the volcanic chain evident in those ranges. The San Andreas fault being a small part of that subduction zone along with the Peruvian/Chilean trench just off the South American Pacific coast. It is believed, that the power of the Pacific plates (there is the main Northern plate, but a complex of smaller plates to the south - Nazcan plate etc...) will actually start to push the North and South American plates against the forces of the Atlantic's constructive plate margin, effectively closing the Atlantic. The upshot of this in some 250 million years time, will be the formation of a new super-continent. This is not unusual. These tectonic plates have been doing this dance for the entire life of this planet and in fact several 'super-continents' have been formed in the past, the last and most noteworthy being Pangaea, which was home to the dinosaurs... Which broke up to form Laurasia and Gondwana (forming the Tethys Ocean/Sea and the Iapetus Sea, then 'Proto-Atalantic...), which in turn broke up to form the main continental masses of today... We thus arrive back at where the video started. BTW, all this info and excellent animated footage can be found right here on UA-cam or elsewhere on the www. :-D So, we are talking millions of years in the future. Given the exponential increase in human populace of this planet, our unlikely chance to survive the next 100 years (note, we are in the Sixth Mass Extinction Event, brought on by our own industrial hubris...), let alone the next million, then I would say, yes, very dumb question indeed. Remember, the forces at play inherent in the earth's crust are THE most powerful forces on this planet. They are extremely slow acting (approx the same as the growth of a fingernail in a year...), but NOTHING stops the movement of a tectonic plate. Our chances? Not good, unless the Anunnaki put in a late appearance by returning to save us... But you have my sympathies....
Depends on what you call screwing up nature. I'd say causing a see as big as the mediterranean to disappear or to appear would be an instance of screwing up nature 'bigly'...
Quite doable, but they are actually thinking of closing the strait to control Mediterranean sea rise due to global warming. Similar things are being discussed for the US around San Francisco as otherwise the food belt will go go under water.
If the Gibralta Straits were to seal up again I guarantee that we would dig a channel to keep it open. There's too much investment in the Mediterranean for humans to let it dry up. As long as there are humans there will be a Mediterranean.
I don't underestimate Human but really none human can fight the FORCE OF MOTHER FUCKING TECTONIC PLATE !

Now as for the gold and other treasures...it would include Roman, Greek, Egyptian cultural trophies among many others.
So...who's got a boat? :-)
I don't reckon they find much life in the deepest parts. The Atacama is a picnic compared to what the Med Desert would have been like.
imagine being alive at the time the mediterranean opened up, that would probably be one the fastest changes to the earths surface ever
Mage craft There have been a few near equivalents. The formation of the Black Sea occurred somewhere around 7000-9000 years ago if I recall correctly.
@@GrahamCStrouse That would have been but a mere trickle compared to the Med filling up.
There should be more geological stories like this one. I trevealed to me something I was not aware of about the beautiful Mediteranean.
It would be fun and go back in time to see the Gibraltar straight break and watch the biggest flood ever happen. Would be fun with popcorn
Cataclysmic inundations are ALWAYS "game changers"! Thank you for this marvelous compendium that succinctly explains what has been ambiguously told, before. The story of this "Middle Earth" Sea warrants attention by those who are tethered to Jedeo-Christian explanations on the origins of Western Civilization, if not humanity itself. Ditto, the Black Sea's inundation, at Bosporus. That recent catastrophe was dramatized by two scientists who wrote "Noah's Flood"; Bob Ballard (of Titanic fame) subsequently searched that Sea's bottom, and found nothing resembling ancient human habitats, however.
There's such an enormous current lowing through the Straits of Gibraltar that it would make a wonderful electricity generation project, and you could have a railway bridge across, linking Europe with Africa.
I've often wondered if Gibraltar breaking contributed to the legend of the Flood, but if it happened 5.5 million years ago there would have been no humans around to witness it.
A more likely candidate is the Black Sea flooding that occurred when sea levels began to rise after the last ice age. It is estimated that sea levels dropped about 130 meters at the last glacial maximum which is a problem when you consider the shallowest part of the Bosporus (which links the Black Sea to the Mediterranean) is about 13 meters deep. The rivers feeding the Black Sea don't have enough flow to fill that body of water completely so during the ice age it would have shrunk to about half its current size. At some point, estimated to be about 10,000 years ago, the waters of the Mediterranean sea rose enough to again top the Bosporus and its waters flooded the Black Sea. Scientists argue how quickly it filled but there is no doubt that whole communities were flooded and cultures had to relocate. Considering that the area north of the Caspian and Black sea is also a probable source of Indo-European language it it isn't too much of a leap of faith to link this event to the many of the stories as its people moved beyond this area.

Agreed. The timing of the Black Sea flooding makes it much more likely, but the sheer scale of the Mediterranean has always fascinated me, so I guess it was some wishful thinking on my part.
Hello, what is the background music? I like it very much!
You must be the only one.
BFDT Maybe some Vaughan Williams? I'd also like to know what it is
I'm curious myself too!

Thank you!
I'm looking forward to seeing the Mediterranean seals featured here.
So the Mediterranean was once Mordor, who knew ! ... The hobbitssss did....
Mediteranean means the midle of earths actually
Well, in German it's simply Middle Ocean. We deny the existence of Mordor!
that would have been Beleriand which has been sunk Mordor is still standing XD
THIS IS WHY THEY SAY ... THE MORE YOU EXPLAIN THE BETTER YOUR EXPLANATION ..... GRAT LESSON FOR ALL
First watch, i liked the pacing and delivery of the content, and the content itself. I got interested from fall of civ talking about the zanclean floods
535M years ago, a camera enthusiast was standing close to the Strait of gibraltar, when he saw a flood gate of water rush into the dry bed of mediterranean sea and he started filming. Indeed it was once in a lifetime opportunety.
Interesting! I always thought that GIbraltar, rising so dramatically, wouldn't/couldn't stay that way.
The Great Basin of Nevada is basically an inland sea that dried up, permanently. Our state fossil is the Ichthyosaur.
This was very interesting and I am surprised and a little sad to see this hasn't gotten more views.
And there is evidence that in HISTORICAL times (like flooded coastlines containing evidence of ancient civilization) that a similar event happened in which the Mediterranean itself broke through a land bridge in the Bosporous and flooded the basin of the Black Sea (which previously was probably a large freshwater lake.)
At 4:18 the temperature of 40 degrees Celsius is definitely NOT 72 degrees Fahrenheit !
40 deg C = 104 deg F !
Why are there so many dumb comments??
I don't know man I was wondering the same thing. A bunch of fucking retards here, even by normal UA-cam standards.
Idk
@Thomas Headley
Shipwreck in the underworld and dinosaur somebody here for ghost sea Hunter is nightmarish the living creatures on the earth was kind of extinct things that island about fossils and bones at the field museum
@@caseypilarczyk9312Yes.
Many years ago I read Julian May, The Saga of the Exiles, this brings me back. 🤗
Fascinating. I bet if there were any civilisations of any description around 5.3 million years ago, those in charge would be blaming the sins of the peasants for the change to what they were used to and demanding they mend their ways.
A lot of this is speculation. Ive heard it described differently in several places. It's possible the Mediterranean basin was habitable. Remember, the Sahara has undergone shifts in climate as well - frequently greening with abundant rivers that might also have fed the basin.
Thats insane! Imagine being there, seeing the flood with your own eyes.
there's an interesting theory that states that this flood is what caused the mythos of the biblical flood. early humans experienced this and it morphed and changed as stories of it were told through the generations
@@Trash_Boat007 What humans were in Europe 5.3 million years ago though?
@@Trash_Boat007 Far more likely that would be the Black Sea flood.
At least two similar events have occurred in human history. The breaking of Niagara10,000 BC (coincidentally the beginning of the Neolithic Era) and the Bosporus around 6,000 BC. In fact, there have been archaeological dives in the Black Sea to underwater civilizations for many years.
Mare nostrum.
During the glaciations the Mediterranean opened and closed many times, not because of tectonics, but because raise and fall of sea levels. The last one might have occured 10k-12k years ago.
Why is it that the Mediterranean is less salty than the ocean if it is ocean water that flooded into collosal salt flats and hypersaline seas?
You have just earned a subscriber. Great presentation.
Great little lecture bud... And nice music too... xxx ;-)
Im from Slovakia.. dam! we had a sea couple millions years ago... "wish i could turn back time.."
I my country was the see too. I seen once the relicts of that world.
fun fact gibraltar derived from the arabic word "jabal tarik" which literally translates to the mountain of tarik referring to the muslim umayyad general tarik ibin ziyad who conqured spain in 8th centuary and formed andalus
Omar Almalouhi It doesn't even sound close to that. It's like saying that the word macadamia nuts are derived from Macedonia.
thank the gods for Gibralter
Good video. Geological history is always so interesting
The Mediterranean sea regulates the sea level of the earth.
Thank you for your factual videos...they stand out.
thanks for the so accurate information ,we still find a fossils at 600 meters about the sea level all around Mediterranean sea
Need to talk about Atlantropa / Panropa like Herman Sörgel planned. He wanted a hydroelectric dam to be built across the Strait of Gibraltar...
From Spain, very interesting.
reading the comments everyone seems to like your work, me too
If this never happend we wouldn't be here today
I´ll think we would..
Maybe we would, but our culture would look different, or even not at all. The Mediterranean sea is the cradle of our western civilization. Not only that most civs lived alongside the shore but euphrat and tigris are also (partly) fed by evaporated water from the sea
With that gone no civs would have formed alongside the Mediterranean, maybe only egyptian, but that would be isolated as no other civ would have formed around it in a desert bigger than the Gobi.
Migration routs would have shifted, maybe we would never have left africa....and formed no civilization at all as all plants and animals used (most) came from eurasia and not africa
The impact of that would have changed our evolution completely because it would have had effects on the climate in africa as well
What about Black sea during this event with sea of Marmara ?
now I want to see an animation of that.
Something like that happened to the inland sea of USA. That sea poured into the Snake River. in I have been there. It was road trip to Wyoming where and it has a rest stop there.
the best video about Gibaltrar, thanks 👏🏼👏🏼🙌🏼
GREAT Documentary!
The continents are shifting a little today. To clarify, because we know this is happening constantly, we are witnessing the exact point of slight continental shift. Geological activity has increased in the pacific ocean recently. This has caused islands to raise and volcanoes to erupt. It's not over yet. Keep watching. Stay tuned and watch what happens next.
Thank you for you very informative and well presented video. I am not sure about one thing you said. What was the mechanism that reduced the salinity of the rest of the oceans when the catastrophic refilling of the Mediterranean basin happened?
amazing ! thank u for posting .
I’m far more fascinated by the background music.
why is the temperature at the dried out Mediterranean sea hotter?
Greetings from the BIG SKY. The Straits of Heracles to the rescue.
Let's talk about Snowball Earth. If the entire world was covered in ice and snow, where did all the water which formed the ice and snow come from, and where had it gone? I mean If the ice sheet was thick enough to cover the tallest mountains, granted Mt. Everest hasn't been formed yet, there must be a hell of a lot more water on earth than there is now!!
That is not it it was just that ice expands way more than water and the seas weren't as deep and the mountains weren't as tall
That ice and snow was ocean, and became ocean again afterwards. Sea level was MUCH lower during the snowball earth period.
12K people watched, around 75 people liked...
You people are mean...
No we're not. 75 people were overly generous.
I would leave a like if youtube wouldn't create a pointless playlist of my liked videos which I do not want, or if at least there would be an option to delete it.
@Ruslan Zarifov Exactly
The odd part is it was a well done educational as well as entertaining video.
I use my like playlist for listening music B) I liked your comment tho
The rain in Spain falls mainly on the plain
...background music greatly detracts from the documentary...
It really doesn't, it's noticably quieter than the voiceover.
The Mediterranian was populated by species from the relatively cooler Atlantic. Since there is the Suez Canal, other species from warmer seas have the opportunity to enter the Mediterranean Sea. Because they are better adapted to the warm water, they are more successful, especially since the Mediterranean is getting warmer, too, because of climate change.
This would not be such a big problem was it not for the irrigation water taken from the Nile. Back when the Nile had enough water, it laid a sweetwater curtain around its delta which also covered the northern end of the Suez Canal keeping back the invasive species. But meanwhile so much water from the Nile is taken for irrigation that not enough sweet water reaches the Mediterranean to keep up the curtain effect to shield the Mediterranean from invasive species immigrating through the Canal.
In the deep parts would be like the Petronus towers standing with 3 more top of each other. Did not realise some parts in the Mediterranean sea got that deep wow .
I know I'm late to the party, but 40C is 104F, not 72F!
This video was done very well
May 2021 Gibraltar shakes to be on topic
excellent video I was just wondering how the Gibraltar Straight closed up?
4:21 it would be fun to know what could live there. It's about as extreme as Antarctica just the other way around. A super hot basin several km bellow sea level. I wonder how the air pressure affected birds. What kind of weather anomalies would it have? How would it's "shore" be?
Because the Med dried for so long it took a lot of salt out of the Earth's seas permanently. Much of that salt is burred under sand and rock deep below the water. The changes in salinity have interesting consequences for the ocean's, their ice formation, and sea life.
When will you do a video about the Paratethys megalake?
I love how you coordinated yourself with the music. Coincidence or careful planning?
I did calculations. For ocean water bringing the Mediterranean Sea level back to normal... for that to had caused the global sea level to lower by 10 meters, the Mediterranean Sea level would only had risen by 1,924 ft. 3,000 ft shallower than the average depth of the Mediterranean Sea. So for that to had happened, the average depth of the shallower Mediterranean Sea before the spill, was 3,000 ft. Then the remaining 1,924 ft increase in the Mediterranean Sea level by the spill would had lowered the global sea level by 10 meters. By the way, if all the Mediterranean were evaporated, not including the Black Sea and Sea of Marmara, the global sea level would be 1,000 ft higher. Or 1,002.7 ft to be exact, based on my calculations from other measurements I found @ Google.
I don't believe your calculations are reliable. Just think - what is the ratio of Mediterranean Sea area to all of the oceans? I find just under 1 million square miles vs. 138 million square miles, so a change in Mediterranean level would be 138 times the greater ocean level change. 10m = 34' +-, 34 X 138 = 4692'. Pretty much what was claimed.
I can't see how the salinity of the rest of the world oceans would decrease with the re-formation of the Med (6:07). I would have thought, if anything, salinity would go up, due to the re-dissolving of the salts that remained in the dry Med basin from previous sea water. When the "old" Med dried up, the salinity of the rest of the world's oceans, it seems to me, would go down as the Med's water evaporated, because the water that came out of the Med would fall as rainwater in the oceans... Thefore diluting it. The overall water volume on the planet would roughly be the same, but the level of dissolved salt changes, depending on the existence, or not of the Med. I am no expert (in anything), can someone please explain. Thanks.
Rapid descent of Oceans due to Gibraltar straight breakout explains Tamaranset basin drain
MIND BLOWN!
Can you imagine standing nearbywhen the whole landmass around Gibraltar broke free?
Good information but, your background music is in the foreground making it had to hear for those of us with hearing impairments. It would be a boon if your audio editor kept that in mind for future videos. Thanks. Keep up the good work.
Thank you for saying this. I couldn't agree more
Amazing video
If we were to build a hydroelectric dam at the Gibraltar and another at the Suez Canal and then allow the Mediterranean Sea to evaporate only a little, like 5-10 cm or even less : we would have so much electric energy !
Can you imagine seeing that flood coming in...
this is going to be a dumb question, but lets say the earth closes the strait again and it starts to dry the Mediterranean. do you think humanity will realize the consequences and try to open it, and if so how much effort would that actually take without really screwing up nature?
Would probably takes some low-yield nukes to blast open Gibralter enough to return to normal.
It is somewhat of a 'dumb question' (..well you said it...lol). This video upload is an excellent explanation of how the Med was formed. And to give 'ZorakGoesOn' his dues, he did say that no-one really knows how the tectonics will 'pan-out'. But here is the current theory (via computer modelling of the ongoing global tectonic shift): As Zorak mentioned, the African plate continues to subduct (push beneath) the Anatolian and Eurasian plates. The Alps are therefor still being thrust up (a process known as 'orogeny' - or crust deformation - mountain building). Eventually the Mediterranean will be effectively narrowed until it becomes a narrow sea-way and eventually close altogether. the Atlas mountains (Northern Africa) will eventually 'meld' with the Alps.
But that is not all... The Indian plate and the Indian sub-continent is also continuing to thrust northwards, in so doing, continuing the Himalayan orogeny. Deformation of the crust along these fault lines will cause a massive chain of mountains ranging from The Iberian peninsular (Spain) to roughly Sichuan in Western China. The Australasian and Antarctic plates are also continuing to march roughly north-eastward and will close up the Island chain of Indonesia/Sumatra/Borneo/ Philippines, in so doing closing the eastern Indian Ocean, which will become a vast inland sea. Bigger than the current Med.
Now in the Atlantic, which is currently regarded as a 'constructive plate margin' is widening; that is to say, it is creating land along the mid-Atlantic ridge. However, the Pacific plate, the largest and most powerful plate on the earth's crust, is subducting beneath the North/South American plates. This action is what has formed the Coastal, Rockies and Andes mountain ranges. With the ongoing tectonic action creating the volcanic chain evident in those ranges. The San Andreas fault being a small part of that subduction zone along with the Peruvian/Chilean trench just off the South American Pacific coast. It is believed, that the power of the Pacific plates (there is the main Northern plate, but a complex of smaller plates to the south - Nazcan plate etc...) will actually start to push the North and South American plates against the forces of the Atlantic's constructive plate margin, effectively closing the Atlantic.
The upshot of this in some 250 million years time, will be the formation of a new super-continent. This is not unusual. These tectonic plates have been doing this dance for the entire life of this planet and in fact several 'super-continents' have been formed in the past, the last and most noteworthy being Pangaea, which was home to the dinosaurs... Which broke up to form Laurasia and Gondwana (forming the Tethys Ocean/Sea and the Iapetus Sea, then 'Proto-Atalantic...), which in turn broke up to form the main continental masses of today... We thus arrive back at where the video started. BTW, all this info and excellent animated footage can be found right here on UA-cam or elsewhere on the www. :-D
So, we are talking millions of years in the future. Given the exponential increase in human populace of this planet, our unlikely chance to survive the next 100 years (note, we are in the Sixth Mass Extinction Event, brought on by our own industrial hubris...), let alone the next million, then I would say, yes, very dumb question indeed. Remember, the forces at play inherent in the earth's crust are THE most powerful forces on this planet. They are extremely slow acting (approx the same as the growth of a fingernail in a year...), but NOTHING stops the movement of a tectonic plate.
Our chances? Not good, unless the Anunnaki put in a late appearance by returning to save us... But you have my sympathies....
Human already built a canal to connect red sea with the Med (Suez Canal) in Eygpt.
Depends on what you call screwing up nature. I'd say causing a see as big as the mediterranean to disappear or to appear would be an instance of screwing up nature 'bigly'...
Quite doable, but they are actually thinking of closing the strait to control Mediterranean sea rise due to global warming. Similar things are being discussed for the US around San Francisco as otherwise the food belt will go go under water.
