- đ Six continents separated by vast expanses of water - this is the familiar image of our planet that we have all shared since childhood. But the Earth hasn't always looked like this. Over the past 4.6 billion years, our planet has gone through many geological eras. During some of these eras, almost the entire surface was covered with ice, while in other periods, on the contrary, the polar caps melted completely.
In the distant past, the continents were not arranged as they are today. Land blocks moved relative to each other, which led to movement, collision of continents and the emergence of supercontinents that united almost all the landmasses.
đ„ As a reminder, videos are published on SUNDAYS at 6:00 PM.
-------------------------
đ„ Pangea:
- The word "Pangea" comes from the Greek words Pan (meaning "all") and Gaia (meaning "earth"), which means "all the lands". This name perfectly refers to the supercontinent, as Pangea was once one land, since all the lands were then gathered in one place.
A supercontinent is a continent composed of most or all of the Earth's land mass. The most recent supercontinent to include all of Earth's major landmasses and arguably the most famous was Pangea. Supercontinents have sporadically joined and broken up over the course of Earth's geologic history.
Recall that the geologic history of the Earth is a sequence of events in the development of the Earth as a planet. Among these events are the formation of rocks, the emergence and destruction of landforms, the advance and retreat of the seas, ice ages, and the appearance and disappearance of species of living beings.
The most modern definition emphasizes that the supercontinent is a geological formation that, with its structure, affects the distribution of heat flows, air masses of the Earth, etc. It is a large structure, but it does not necessarily unite all the continental blocks.
In the distant past, all the continents formed a single whole, the supercontinent Pangea. This huge continent began to form about 335 million years ago, during the Paleozoic period.
During the process of formation of Pangea from older continents, mountain systems appeared on the places of their collision, some of them still exist today, for example the Urals or the Appalachians.
These early mountains are much older than the relatively young mountain systems such as the Alps in Europe, the Cordillera in North America, the Andes in South America or the Himalayas in Asia. Due to erosion over millions of years, the Urals and the Appalachians are now low mountains.
Most of this supercontinent was concentrated in the southern hemisphere. The only ocean that surrounded it was called "Panthalassa".
Life during Pangea was different from today. The climate was warmer and the fauna and flora were completely different.
Pangea split about 150 to 220 million years ago into two continents. The northern continent of Laurasia then split into Eurasia and North America, while the southern continent of Gondwana then gave rise to Africa, South America, India, Australia and Antarctica.
Supercontinents existed earlier, for example Rodinia, which disintegrated about 750 million years ago, and according to some predictions, in the future, the continents will reunite into a supercontinent called "Pangea Ultima" in about 250 million years, when Africa, America and Eurasia will collide.

Logical choice. The cameraman never dies. đ

Imagine how many animal species have existed through time. So many creatures that didn't get to be preserved and discovered, forever unknown to us.

That's why planet earth has so much fossil fuel.
@@justinc4924 I concur
@@maryjeanjones7569 ummmmm you are dumb
@@maryjeanjones7569 Actually, most of the earths fossil fuel supply is from the carcasses of ancient swamp trees that would die and just sink into the swamps instead of decaying. I just recently learned that the dinosaur thing is mostly a myth because in order for coal to form it has to have an absence of oxygen and most dinos died in the open air and decayed.

I hope they left the light on for him!
I was a member of the crew on the Lamont Obserivatory's R/V Robert D Conrad-AGOR3, in 1967. We spent months at a time collecting ocean core samples, collecting sea floor densities using recorders that picked up sonar type blast signals from the ship to a series of trailing microphones that plotted the information on a continuous roll of special paper. It was a experience that I was so lucky to have been part of as a 21 year old.
We researched the whole globe usualy 30c days at sea and a brief time in port. I spent 10 days in Tahiti on that leg of the trip. I photographed so much, and could write a book about my own personal experience of the adventure. I'm in my late 70's now, sometimes it's hard to believe that the journey ever happened.
Great experience! Thank for Sharing! What was your favorite discovery?
@@SnarlaRae It took a long time to drop core tubes to the ocean bottom and hours to wench them on deck. During this time some of got to swim in clean clear pristine water miles deep. We drop special cameras(primitive to what is used today) They had no shutter they would load a hundred foot roll of black and white film with a very slow winder, there was a strobe flasher to record the what was happening. We would sometimes see different life pass in front of the view and then when it reached the bottom it would rest for a while, flashing before being raised up to the ship. Twice we saw human related debris, one was some kind of can and the other what appeared to be a beer or soda bottle. We had a small clamshell bucket that would take samples from the ocean floor, when brought aboard would almost always have manganese nodules, they were everywhere. We had what looked like an old water heater that had a flapper system top and bottom that we drop into the sea to a prescribed depth to collect a sample of the water which we checked for radiation. The system worked by letting water flow through easly and then would close up and seal that desired water to stay trapped for study.
I bought a copy of Kon Tiki before boarding the ship. (I read 2 to 4 books a week when I was aboard ships) There is so much to talk about. Every minute I felt like I was in a movie.
In 1973 I was on another ship in the Pacific, you would find trash and plastic every where, we watched on piece of plastic float by and before it was out of sight another would come into view. While back in 1967 we very seldom found trash floating by.
Sorry for so much talking but when I get started i could talk all day about it. Most people and my friends hardly even know anything about this time in my life.
@@lancebon2931 No need to be sorry. â„ïž I like reading your experience. Thanx for sharing. I had no idea about Kon Tiki so thank you for that tidbit. I will be looking for the Documentary.

Yall are pathetic.
We probably all learned this stuff at school. It's just nice to play it back again years later,
knowing that, for our planet, no time has passed at all.
You obviously didn't go to a very good school ! The "Pangea" is only one of many THEORIES, taught when I was at a very expensive school (1960's). A Theory which fails to take into account the Mechanics of the shape of the Worlds Tectonic Plates !!! Certainly planet Earth went through a "Cataclysmic" period not long ago (6000-10,000 years ago), which mainstream science is only now just beginning to wake up to. For that however you need to read Prof Velikovsky's mind boggling work "Worlds in Collision" published by MacMillan in 1950 !!!

@@kimmmm8587 same. I always just play one and set my phone down and just listen
I like these types of videos because they remind me just how short our lives really are.
Statistically, based on the views and time since posting, 13 people who watched this video has since died.
Assuming the elderly are less likely to use CZcams, that number is much, much lower.
Specks in a spark.
You LIKE to be reminded how short your life is??
Agreed!
Especially this one, since I found the narrator to be speaking slower than most, so it definitely reminded me of that fact lmao
Same, I find it comforting somehow to be reminded I am just a small speck in the universe.
I bet taking a time machine back to those days would feel like youâre on a completely different planet
Biggest difference: it was clean and pristine, no humans polluting it!
Humans couldn't survive long back then. The atmospheric oxygen content at sea level was only 15%, which is like breathing on top of a 15,000-foot mountain.
@You're Wrong Since "the beginning of time?" So you believe humans have been around over 12 billion years? Or are you referring to the beginning of our planet? That's 4.5 billion years. Please enlighten me.
@You're Wrong Nothing magical about it. Biological evolution.
â@user-md5ko4et9q do u think aliens probed humans you know where
I believe the reason Pangia broke up is because, all that mass on on one area on the surface is because it made the planet wabble, so the plates moved around until the wabble stopped
Actually it's probably the convection currents in the mantle combined with rifts. But who knows really.
Well.. I the first seven minutes you have told me about fifteen times that there was a âsupercontinent called pangĂ€aâ ⊠I think I got it now -
Miles Davis wrote an improvisation called 'Pangiea'.
Such a gorgeous planet, being a geologist, I am so fascinated by its existence.
like an alien world used to be here
How wonderful! Geology is one of my favourite subjects, though admittedly I'm a layperson . Our earth and the processes which formed it fascinate me as well.
â@@harrietharlow9929
I think we came before with 3D printers; put all these lovely life forms here, borrowed from a doomed former home, got snowed in, our lifespans brutally shortened, and forgot all about our origins; except every religion on Earth has an instinctual memory (we never truly forget) of celestial origins and somebody churning out life forms out of "clay".
I think the "WORD" that supposedly started it all is code for DNA; and it wasn't magic, it was science, the same that we're using now to create esophaguses and bladders and soon hearts and the rest of it. Give us time, we can play God as good as the next guy.
Jesus also seemed to be saying that for Life to be "Everlasting, Amen", we're going to have to do it again and head to "Heaven", the next planet, when the Sun we now live by goes wonky, which it's predicted to do. We're the "chosen" critters to take it all upstairs when the time is right. "Made in His Image". And we're going to pull it off with War Toys, go figure !
I"m a gynecologist and I'm fascinated by you.
@@harrietharlow9929 me too. It's utterly amazing what is in the land around us when you know how better to see it.
I recall in second grade looking at a globe and thinking how the pieces fit like a puzzle.
As usual, the cameraman is immortal and untouchable
Itâs god didnât you know?
immortal? really??
this joke is overused
Ik right haha I even witnessed the camera man filming the universe just right after the big bang
Immortal? really! You forgot the artists that promote the agenda.
It blows the mind. Just how much time has passed. So much change and yet we seem to perceive things as always being there entrenched in stability against time when all around us is changing all the time
Love this comment †very true. Time is a massive illusion as is reality. We donât understand these things at all. The world and existence is not what it seems.
That is a problem for humans and their relatively short linear lives, with one exception, the ability to appreciate the ephemeral!
Makes you wonder what mysteries were destroyed by all the change over such a long period of time.
He meant to say 335 years ago not 335 million so really pangea wasn't too long ago
This was just amazing, thank you! It is hard to wrap your head around and yet so integral to what we now identify as our world! I used to work at the Grand Canyon, which is 2.5 billion years old and it always just boggled my mind with it's ancient beauty! What a truly beautiful planet, Earth!

The Earth's history of life is incredibly. Grateful for the people who were able to uncover some of it's history, but we are only able to find out the things that have left evidence behind, I can only imagine the things that we are unable to discover. Who knows what kind of life forms and geological marvels that once were. I am at awe of life and existence.
Correct itâs been here before humans itâs gonna be here after humans
Pangea is an interesting myth at best or rather a hypothesis yet to be proven by actual verifiable evidence. to many limiting factors in the way of this being a real earth millions of years ago

This is very true. I used to live in Pangaea. But back then we called it Piklu

The i-diz in this video are so fascinating! Love hearing different i-diz and maybe even coming up with i-diz of my own.
Thanks for this upload. First timer to your channel. I enjoyed this very much. Thanks for your work đ
I mean...Pangaea was around for a long long time: 90% of the Permian and at least 70% of the Triassic. And Permian Pangaea was VERY different from Triassic Pangaea.
Great documentary.
What if during that time, there was a hyper advanced pangean civilization beyond our imagination that vanished beneath the craters of earth due to a global catastrophe after they have left this planet? This could explain the various unresolved mysteries in histories. They have returned to this planet, visiting us which triggers our imagination about UFOs
you mean assassin's creed 1 scenario ?
Yesss
We have fossils ten times older that the continent of Pangea (3.5 billion years old Cyanobacteria) yet the oldest "advanced" civilization is the sumerian roughly speaking 5000 BC. Just to put things into perspective
Awesome documentary â€

Maaaan⊠can you imagine how long it must feel to live day in day out for 300 hundred million years.. seeing the the sun rise and fall for an eternity and the sediments recede and the landscape ever slowly form new terrain day by day for three hundred million years.

"...of all the continents coming together like a puzzle, is incredible."
Some guy: forcing two puzzle pieces together that don't match so theres all kinds of deformities
"Incredible"
I love to have your brain for a day. Must be very relaxing.
âDeformitiesâ as opposed to the only reference youâve had in your short life? You realize thereâs more science to it than âhuh these fit like puzzle.â Right? They are portraying this for laypeople who couldnât even begin to understand the intricacies of geological, paleontological, and archeological sciences. Or in a more simple way of putting it, itâs made for the dumber people on the subject. And so we are clear thatâs ok, itâs ok to trust someone whoâs done the research and taken to time to learn about something so well that neither You or I couldnât hope to match them unless we did the same, rather than base my beliefs on my own presuppositions like most animals do. And you want to know the best part since I bother to actually listen and try to learn and understand the topic I actually learn something and Iâm able to explore and delve somewhat into the topic on my own now that I have a set of bearings to work with. You should try it some time itâs rather fun and educational.
When you work in a foundry setting, the stuff on top of the hot liquid metal is called "slag" (in my experience) To me it seems that the continents are a type of slag on the top of cooling liquid. Hot spots are convection currents. I just watched my eggs coagulate in the frying pan as I cooked them and I can imagine similarities between it and Pangea's reaction to heat too, IMO.
Exactly. I've always thought of it that way too
Oceanic crust is made up of basalt, a much more dense type of rock than the continents, which are comprised of lighter granitic type rocks. Not necessarily granite itself, but assorted rock types made up of lighter minerals derived from granite. This is why ocean basins dive beneath the continents during tectonic collisions. Both oceanic (basalt) and continental rock (granitic) are lighter than the underlying rock layer and so "float" upon it. "Hot spots" are plumes of molten magma that has risen from deep below. It is different but somewhat related phenomenon than the molten uprisings that drives tectonic plates apart, either continental or oceanic. There are areas of the earth where plates are being pulled apart on the continent, one such area is the Great Rift Valley in Africa. However, most plate separations occur in the ocean basins.
Slag has such a different meaning in the UK. đ€Ł
@@mahelaniarektbb no, what the commentator describes has always been called slag in the UK too. It just has a second crude connotation
You got it right. Basalt, the dense glassy rock from volcanos is at the bottom of the sea, coming from the Mid atlantic ridge. What we are standing on right now is anthracite. This gets made in the subduction zones, which is what we call the Ring of Fire. as the plate edge gets pushed down into the mantle, it melts and mixes with seawater, which lowers the melting point and density. Very weird to think of granite and anthracite... you know, "bedrock," as if it were pumice stone, but that's how it is. The continental crust floats on top of the plates, we walk around on it, until the plates get subducted again millions of years from now, and more crust is added.
Absolutely beautiful videođđ

Does anyone know where the narrator's accent is from? He says the word 'idea' in a way I've never heard before, and now that I've noticed it, I'm realizing how often he needs to say it for a video about scientific theory, haha
I had to stop watching cause the way he says "ideh" was so out of place and jarring it was actually kind of infuriating. I've done some accent and dialect study and the narrator sounds like a mishmash of midwestern american sports announcer and recieved pronunciation british, but only on the word "ideh". Makes me think they're either a british VA doing an american accent or an american VA who studied for their narrating voice from watching old black and white films with transatlantic accents. Weird af
@@Reticulating-Splines Same! It was fucking awful, I think it's an AI voice to be honest.
It's so weird! Only one word different from the rest of his accent. Perhaps he's a human from Pangea days who came to the future just to tell us about his supercontinent. And by chance they spoke exactly like Americans apart from the word "idea."
I was scanning the comments for 10 minutes looking to see if anyone else was as bothered by this as me. Thank you for confirming lmao
Omg I really thought i was the only one. Came looking for the comment and had to scroll way too much

This is amazing
There is a land mass recently covered with water only 3-6 meters above it's surface and is located just east of the Polynesian Islands!
Theia also caused a recoil, like when a drop of water falls into a body of water, then when the moon coalesced it too would act upon that very area which the recoil would have raised allowing a falling motion to begin and would continue as a fluid would on a sphere of liquid suspended weightless in space. Internal convection currents would also play a part after the strike from Theia had set up the crust for such movement!
what or who is the Theia
Theia was a planet from the very early days of earth, when it was just a ball of lava. Theia orbited very close to earth, and at one point crashed into it. The space debree formed the moon.
Narrator's voice is amazing.

You had me until the horseshoe crabs. They are not only found in the Gulf of Mexico and around Florida, but they are also found all over the Eastern North American coastline. Using the hypothosis that the ones in the UK are connected to the Gulf of Mexico because they can only be found there is preposterous. I have lived in Maine, Rhode Island, Norfolk VA, and have visited and vacationed in every state down to Florida. In years past they were EVERYWHERE on the east coast, but they have started capturing and killing them for their rare blood, so you really don't see them anymore. Neither do you see the shells on the beach you used to see. Damn us all for taking other things into extinction just because we can.
This is a fatal flaw in this work.

I love the eerie soundtrack. Hate love these videos cuz it reminds me of our mortality and how we will all die eventually in a quiet peaceful way or l in a catastrophic natural event and suffer horribly.
I'm confused regarding the comments about how horseshoe crabs can "only" be caught near Florida and the Gulf of Mexico.
Anyone from New England should be very familiar with these ancient and interesting fellows. They're all over the shores that are sandy and (relatively) calm in places around New York City, Long Island, Martha's Vineyard, Nantucket, and Cape Cod. One can find, literally, PILES of them during their mating season. One on its own is big, 7 clinging to each other is totally impossible to miss.
If it wasn't for the piles of mating Horseshoe Crabs, I'd never get laid. Also: I call 7 of them an orgy.

I'm going to say no..
Actually we have plenty of room now. Over crowded planet is not at all true. The reality is that we are just compacted into dense urban areas. If we went back to more spread out living forget city living and think town, village, and hamlet things would not only be better for us but also far better for nature and environment. Sadly its unlikely we will ever go back this style of living due to ploitics which is the core problem we need to solve before we can focus on all the other issues.
Sad but true.

@Justin C Sorry my friend but its u who have spelt it wrong. Mike Young has the correct spelling. I am in no way being an asshole just giving u a "friendly heads up!!"
uhhh not its not LMAOOO@@justinc4924
Uh, horseshoe crabs also live in the Chesapeake Bay area and along the US east coast. Most of them seem to be in the bay these days.
The best documentary is nature documentary.
I'm hooked. Following with interest
Horseshoe crabs aren't only fount in those two places. They are also found all up and down the coast of North America. I lived in Delaware growing up and we learned all about them and how they are used in makeup production. Check your facts.
You should do something about the music volume.
So well made ! So glad I found it.
Horse shoe crabs are also found in New Jersey. They are so amazing to see in person. They are quite large and look dangerous, though they are not. They donât bother humans when theyâre ashore.
Imagine having a beach house and you end up in the middle of a continent
About 335 Mya there was only one continent. This continent" was" called Pangaea . The continent IS called Pangaea . There was nothing then to call it such .
I am almost sure this presentation was translated from another language. There are many mistakes (like Bay of Mexico rather than Gulf of Mexico) that show the translator did not have a background in geography or science and the narrator was not terribly educated in the subject matter.
My high school guidance counselor in the mid-1980s told me i should become a computer programmer or a wildlife officer. I realize now she had no conception of how I should become a natural historian. I did make good money running a satellite TV repair business for decades, but my favorite part of that job was the rock layers my work took me across. And being self-employed, i was always free to stop and study any rock outcrops I traveled by.
Loved the captions for this...supercontinence instead of super continents đźđ
Interesting that even at the time of Pangaea, the US had its state borders, but all other countries were national borders
That is interesting, especially considering today it seems the US doesn't have a national border unless you are a citizen trying to fly back in.
Literally identical to earth today but the animals and trees were bigger. The thumbnail would have you believe Pangea looked like the shivering isles from Oblivion
PangÀa
I need to unlearn the word "idea" and relearn it after this đđ seriously though, awesome video.
I learned this in Grade 5 from a National Geographic article in 1973. I did my speech on it and my poor teacher did not have a clue what I was talking about. Knowing this was handy in highschool; there was always a question about plate tectonics on geography exams.
I really enjoyed this explanation, it was chock full facts and answers to questions I've always wondered about, thank you very much for the research and being so thorough! I am looking forward to your next video. The effort you put into trying to get this video perfect is very apparent. I think you should spend more time writing and rehearsing, it will save you time when you edit. You should not be routinely cutting and splicing mid-sentence, or adjusting the volume of the music.
NOT FACTS ! It's full of Suppositions, & "best guesses" by those with "tunnel vision" !!! As the NEW STATESMAN called it Quote "The Post truth World" Unquote, in reference to the increasing "dumbing down" damage the Internet is responsible for !!!!!!!!!!!
what's that got to do with the explanation of this crucial information
It's going to be cool when AI will be able to make it seem like it was shot on actual video.
AI WILL KILL all Humans!
Unreal engine?
The way the narrator says the word' "idea" is hysterical. "Idaaaea"
Great video
I remember being four and looking at a globe and thinking wow itâs like a jigsaw puzzle that spread out I honestly canât imagine how forhundreds of years people looked at the map of the continents and did not ever think well these probably started out and moved the scientific credit goes for proving it through the fossil layer with the concept that the continents were once all together and like a dinner plate shattering on the kitchen floor were spread apart now I just donât know how anybody could look at a globe and not think these things were once together
Simple because we didnât have detailed maps of all the continents until recently.
You're not alone in noticing this. When I was around six or seven, I noticed the fit between South America and Africa. Being young I described it as "South America goes out where Africa goes in". It being the late 1950s, I was told that it was merely a coincidence. I was blown away when in my 20s I first heard of plate tectonics, proving that I was right, And not only one supercontinent, but a series of continents, reaching back billions of years.
People thinking that masses of lands having once been massed together, goes back to at least the time of Francis Bacon. That's when the first reasonably accurate maps began to be produced and, like us, Bacon noticed how the continents seemed to fit like a puzzle.
Interestingly, some scientists think that the process of plate tectonics has (just barely) begun to reverse, since they found what appears to be an infant subduction zone forming of fthe coast of Portugal and Spain, meaning we may be seeing the very first stirrings of the closure of the Atlantic. Already, Africa and Europe are being brought together since the Mediterranean Sea is closing. but all of this will happen over the next250 million years.
You are not alone, and my third grade teacher, in 1950, said, "Oh no, Margaret, it's just a coincidence!!" I knew she was wrong, and thus began my deepseated doubt in "received wisdom."
I was told in gradeschool that "everyone notices that but it doesn't mean anything."
By the time I got to college, plate tectonics were gaining ground, but it was considered kind of cutting edge to believe it.
Until a mechanism for the movement was figured out, it was hard to imagine how it could work ...
@@melodiefrances3898 The mechanism for movement was definitely what tripped up contonental drift.
@19.30...Florida did not exist up to 50 million years ago but Spain and Portugal did although not part of mainland Europe. One cannot speculate what fits into what until one reverses all Continental Plate movements back in time to a specif time. Its about the World Coastlines then, not now. Also, subducting plates do not completely melt as stated, see work done by Karin Sigloch that also includes Slab Rollback.
This video is so full of storyline holes that the comment about it being written by a high school student may be exactly right.
@@ffrost8353 Yes, it's a very odd combination of things that are correct and things that are, well, whacky. Which might be worse than something that is just 100% , as the correct information may trick people into believing the whacky stuff.
Glad i was able to read this comment, i was questioning my own knowledge like how the hell did he came up the Florida and Gulf of Mexico hypothesis when the distance between the plates, time of rocks, and position of existing coastlines did not jive together based on his narrations
Awesome documentary! Honestly kept thinking Chris Dâelia was the narrator though đ. âThe horseshoe crab, nicknamed, horseshoe crabâ
Watching from Greece.hi everybody.
Great documentary.
Great video! Only thing that threw me off was that you said â6 continentsâ. Are we not differentiating North and South America or is Antarctica not a thing anymore?
I noticed that, too đ
Some people have insisted that "The Americas" are a single continent because they are not separated by water - so there are only six continents. To which I reply that there are only four since Afraisiurope must be a single continent as well.
Europe and Asia are technically one continent, not two. Ppl have also debated whether austrailia is a continent or a large island
@@haleyjj1998 Hold on let me look out of my window, yes Australia in an island continent. Actually, given the fact Western Australia has some of the oldest ancient continental craton crust, it has to be viewed as a continent.
Considering how little land connection they have, it seems pretty crazy to me that anybody would treat the Americas as a single content, unless they were already joining Africa, Europe and Asia into Afro-Eurasia, anyway. I think the best case could be made for joining Europe and Asia, given the breadth of their connection and the fact that they're on the same major tectonic plate. Of course, there are historical / political / cultural reasons to treat them as different entities, as well as sheer stubborn habit, I suppose.
Maybe turn the music down a little so we can hear the speech better? Right now the balance is a bit off, the music is too loud and the voice is too quiet.
Mind blowing
Nice video, đœđ
Funny, as a small child, the first time I looked at a map of the world, I noticed how the land masses fit together like a jigsaw puzzle. I would think people would have noticed that centuries ago.
They did, they couldnât prove it.
Cheers youâre average!
To think, even if you had a time machine, you would be dead within minutes if you were to go back to that time as Earth's atmosphere was very different.
I only realized I had already seen a video from this channel after I recognized the narratorâs unique way of pronouncing certain words and his intonation. âIdeahsâ
I would so like to know where your photographs were taken. They are marvelous. Can you annotate the pictures? It would be so interesting to me and perhaps others too. ps So many of them appear to be sedimentary rocks. hmm
