Nothing really happens in a million years in plate tectonics. Yeah some continents may move a kilometre or two, or existing rifts may deepen and what not. The fastest plates only go a few cm per year, in a million years that's only 10-20 km. There a few interesting spots, like the closing of the Strait of Gibraltar which will wreck havoc in the Mediterranean, causing a new Salinity Crisis. Or the closing of the Red Sea. But on a global scale it doesn't really matter if the Atlantic is 10 km's wider or Australia has move 15 km's to the north(apart form becoming even hotter). It's in the tens of millions of years that really interesting things start to happen, like a new mountain range like the Himalayas where the Mediterranean Sea is now, due to Africa moving north. The split of North and South America. Australia & Guinea ramming into the Philipines or the break-off of the eastern part of Russia to melt with Alaska.

This is a huge project: the entire earth in half a billion years. Thanks Chris. I hope one day you get a bunch of grad students, each concentrating on just one of the continental pieces, and then you assemble the results. that way, this would be not only accurate in generalities, but also in specificities. For example, the entire history of the Urals is fudged over, while the Asian-European collession should be somewhat the center stage at some point, the creation of the Tethys. The opening and closing of the Gulf of Mexico, the Eranic micro plates and gulfs, MacKenzie-Missouri sea, as well as the Mediterranean, leading to so much removal of salt from the earth's oceans to create a "Salt" crisis never mind the oil beds creations, and dozens of microplate moving about.... Remember, EVERYTIME you have huge salt deposits, that tells of the place having been a trap for the sea water, meaning it keep getting flooded, then evaporated, then flooded, then evaporated over and over again, leaving behind, miles deep salt deposits. So, just follow the salt foot print, and it tells you where the sea/salt traps were: Gulf of Mexico, Iran, Canada-Colorado, Baltics, Mediterranean, central Asia..... All the same, thank you for your time and the great film.

With all that geological mystery going on near Gibraltar, one might think Atlantis might have been involved, if it existed.

[@vasilisiatropoulos3474]

@@RodMartinJr From what I understand, the Messinian Salinity Crisis lasted from about 7 to 5 mya. Some marshlands & large lakes persisted though in the deeper areas, thanks to river flows (some speak of an impressive waterfall at the mouth of the Nile !), throughout that period and that is the source of significant hydrocarbon deposits today. There's compeling evidence that there are also Jurrasic deposits from the long gone Tethys sea even deeper .However, the Med is destined to disappear in a few tens of millions of years, and give way to a large mountain range similar to the Himalayas as Africa will eventualy collide with Eurasia. It's a fascinating story in all.

[@RodMartinJr]

@@vasilisiatropoulos3474 yes it is a fascinating story. Kenneth Hsü's original thesis had the earlier date, but the latest figures I've seen peg it at between 5.9 and 5.33 Mya -- right at the end of the Miocene Epoch, during the Messinian stage or age. There is some evidence that as the northeast corner of the Africa plate collided with Eurasia some 40-50 Mya, the event triggered temporary stoppage at the triple junction at the MAR. This may have resulted in folded crust at the new crust east of the MAR -- enough of an impediment so that subduction was blocked locally, though it continued all along the Africa-Eurasia boundary, except where it had collided with what is now Persia. This resulted in the Africa losing part of its mass, giving birth to the Arabia plate, and starting the shearing which continues even today as the Rift Valley and the as yet incomplete formation of the Somalia sub-plate. With a persisting impediment to subduction, the Africa plate boundary became increasingly folded, as evidenced by the jumbled nature of the ocean floor in the region, today. But back then, as the folding continued, the northward thrust of the Africa was converted, locally, into an upward thrust, forming an island. This plate boundary damage continued until the upward growth could no longer be sustained. This effectively stopped the northward movement of the Africa plate, locally, while subduction continued along most of the Africa-Eurasia plate boundary. This west-side impediment resulted in the Africa shifting its Euler pole of rotation with respect to the Eurasia to near where it is today, about 1,600 km SSE of Terceira Island. About 35 Mya, this rotation began, as evidenced by the sudden bend in the Africa-Eurasia boundary at the eastern edge of the Azores underwater plateau. The young spreading center (ridge) from that bend and up to the MAR also support this thesis. Plate fractures across the Sahara date to the same period as the Africa underwent the stresses of the change in plate movement. Like a paper jam in a printer or fax machine, damaged plate boundary next to continuing subduction forced the creep of boundary damage eastward, enlarging the island. After about 30 million years, the folded crust reached Gibraltar, blocking the entrance to the relatively new Mediterranean. I discuss some of these details in my book, *_Proof of Atlantis?_* including evidence from 3 different scientific disciplines that correspond to Plato's date for the demise of that island

[@marclinquist5558]

Part 1 Hello Dr. Scotese, this was absolutely breathtaking to watch. Thank you!!! I found it far too important to not stop and comment on this subject. And more specifically, to allow me an opportunity to express an opinion as to the true and accurate description of the mechanism involved in plate tectonics. It’s interesting when you consider how much the standard model is dependent on the mantle having a convection regime. The great Arthur Holmes is credited to its acceptance in geology and the suggestion it could be the missing energy source to drive the tectonic plates. But, he also readily admitted it could be wrong. To date there is no direct observable evidence of the mantle having an up welling of lower density material resembling a convective cell or even a conveyor belt type of mantle movement beneath the tectonic plates. The standard model is only speculative in these regards. But even more importantly, the surface observations over the years have continually presented evidence of a mechanism of plate movement far different than what convection could provide. The mantle appears instead to be a solid state material that is 2,900 km thick, with pressures so great that at only 100 to 250 kilometers carbon can be squeezed into a diamond matrix. There are now a growing number of researchers who are skeptical of the standard model’s over-dependence on such an overly simplistic idea. Carlo Doglioni, the geophysicist and former president of the Italian Geological Society, and since April 2016, the president of the National Institute of Geophysics and Volcanology has published some very remarkable papers in regard to mantle dynamics and plate tectonics. www.dst.uniro...antle_Dynamics_ MANTLE DYNAMICS AND PLATE KINEMATICS Carlo Doglioni, La Sapienza University, Rome, Italy Roberto Sabadini, University of Milan, Italy ". . . . . none of the proposed models of mantle convection can account for the simpler pattern in plate motion we observe at the surface, nor has a unique solution been proposed for how material in the mantle convects. At the moment there is no way to link mantle dynamics and plate kinematics at the surface, considering that the mantle and lithosphere are detached. The Atlantic and Indian ridges are in fact moving apart with respect to Africa, proving not to be fixed both relative to each other and relative to any fixed point in the mantle. This evidence confirms that ocean ridges are decoupled from the underlying mantle." This remarkable observation above expresses the reality of the situation. Geologists need convection to be a viable solution to plate movement, but after 90 years, its existence, let alone its functionality, remains unanswered in the standard model. Taking the following to heart; “nor has a unique solution been proposed for how material in the mantle convects” Reading what is being said in general publications; you would never suspect that there was a problem. A great deal of faith is involved in the idea that the Earth’s mantle has some sort of fluid like behavior that could provide a drive mechanism. Then there is the problem with subduction initiation and the general idea that the oceanic plates can just founder and sink to the bottom. This is expressed repeatedly without even contemplation of the difficulties involved. None of this plate behavior has been observed. What should be trusted is hypotheses’ based on predictions that are supported by observations, and the observation by Doglioni above falsifies much of the supposed credibility that the mantle convection hypothesis has been given. Consider the planet’s internal heat budget; blogs.scientificamerican.com/observations/nuclear-fission-confirmed-as-source-of-more-than-half-of-earths-heat/ ”The new measurements suggest radioactive decay provides more than half of Earth's total heat, estimated at roughly 44 terawatts based on temperatures found at the bottom of deep boreholes into the planet's crust. The rest is left over from Earth's formation or other causes yet unknown, according to the scientists involved.” There is however another way for the Earth to dissipate energy, and a new model that can make an unprecedented number of predictions of observations of it. If we were to instead consider the mantle as an extremely dense and in-compressible solid under extreme temperature and pressure, a strain energy cycle could be imposed on it as the planet’s magnetic field generator slowly changes amplitude over million year time scales. This mechanism is not directly derived from the Earth’s magnetic field energy, but from the kinetic energy that occurs when the inner core and outer core thermally expands or contracts against the mantle’s density and viscosity. In what is simply a strain energy displacement, the mantle’s 2,900 km thickness creates a massive strain energy differential between the inside and outside surfaces of the mantle as it is forced to slowly expand outward, and then contract again over million year time periods. The strain energy increases proportionally with the distance from the core by way of the inverse square law, resulting at the crust/mantle boundary with maximum expansionary movement and thermal release. This BTW would result in exactly what Dr. Doglioni described above; “At the moment there is no way to link mantle dynamics and plate kinematics at the surface, considering that the mantle and lithosphere are detached. The Atlantic and Indian ridges are in act moving apart with respect to Africa, proving not to be fixed both relative to each other and relative to any fixed point in the mantle. This evidence confirms that ocean ridges are decoupled from the underlying mantle." As the mantle is slowly displaced the mantle’s outer surface area would be slowly stretched out and torn. These oscillation cycles would take millions of years to complete. Yes, John Joly was on to something that was close to the same idea. And one could wonder if Hannes Alfvén’s magnetohydrodynamics had preceded convection, that Joly’s idea may have been all the more obvious. So, what predictions can this model make? Well, there should be direct observational evidence in the solar magnetic proxies that there is a clear correlation between solar magnetic energy levels and past climate variability; increased solar activity will correlate to increased strain energy at the crust/mantle boundary leading to seismic and volcanic responses timed to deep oceanic and climate warming. Then when the solar magnetic energy levels fall the planet will begin a period of cooler climate. The strain energy displacement of the mantle will be marked in the solar magnetic proxies with specific occurrences of earthquakes timed to rapid changes in solar magnetic energy. This new model presents a very simple process for the development and initiation of plate tectonics and also how divergent and convergent boundaries develop and change over time. The many unanswered problems of the standard model are explained with remarkable ease. The processes leading to subduction initiation and its continuance are explained in a most understandable and likely order of events that are not explained very well at all by any other model. Occam’s Razor is very much at home in this model. Let me quote directly from the model; “The Himalayas are currently rising and that would seem to be counter-intuitive to any idea claiming that you could have a period of increased Solar magnetic energy (as we currently do) producing a slowly outward displacing mantle that could be separating the mid-ocean ridges in the currently observed manner.” www.electroplatetectonics.com/

Nikolay Andreev they're still growing so possibly.

[@DieFlabbergast]

No way to know, but quite possibly. The northward march of India was probably one of the fastest tectonic processes in geological history. By comparison, every other "collision" of plates was just a sort of slow oozing together. What is unique about the Himalayan orogeny is not really the height of the mountain chain, but the enormous Tibetan plateau beyond it.

[@raverdeath100]

as others have already pointed out, it's hard to tell if the Himalayas are the highest mountains to have existed but you may be unaware of the subsidence effects currently happening. as the crust crumples, the rock doesn't only rise but it "falls" as well, sending massive mountain roots into the magma region. the southeast region of the Himalayas is already subsiding as the roots there are eroded by the magma and are no longer able to support the weight. Death Valley (in the US) is a good example of where this effect has already happened.

[@mosquitobight]

I think the Trans-Hudson Orogeny in the Canadian Shield was considered to be higher than the Himalayas. And 100 million years from now, the ongoing collision between Europe and Africa will probably turn central Europe into a mountain belt higher than the Himalayas.

Even though my sister, brother and I picked out all the rocks before planting, there were more the next year! That's when my dad introduced me to the "stacking plate" theory. Just like dinner plates that rise to the top at a buffet, our rocks were doing the same thing. Take one out and another will take its place over the course of a year. At 8 years old, I did not find that amusing. Five cents a bucket didn't cut it. 😡

[@Dragrath1]

I recommend looking up granular segregation as that seems to be the effect you are describing www.annualreviews.org/doi/full/10.1146/annurev-fluid-122316-045201 Basically in a system with granular particles of various sizes disturbances can enable smaller particles such as dirt and gravel to fall between larger particles such as rocks over time effectively pushing rocks upwards. Erosion and sedimentation help counteract this by producing new small particles but alas it is a never ending process. Also depending on where in Washington you were it may have been glacial dam burst floods instead being carried down the Snake and Columbia river systems and carving the scab lands.

All of the observed tectonic plate domains that are semi-rigid and separating are matched by other domains which are converging. It would then be most critical to any plate movement model to incorporate these facts into its description of operation. This model is dependent on a tremendous shear resistance between the crust and mantle that moderates the distribution of the compression that slowly moves away from its source at divergent boundaries to its final disposition at a convergent boundary. This is in part due to the isostatic equilibrium that is distributed at much lower values due to the compression that is now present in the global plate matrix. For example, the Himalayas should not be anywhere close to the height that they are at. They should be sinking into the mantle at this moment. But, this model can explain this paradox by explaining that the Earth's entire plate matrix is, to some degree, being held in a compressive load state by its shear resistance to the mantle. Imagine how compression alone can hold a long series of un-mortared bricks in suspension without falling. Now if these were instead massively wide plates lying over a planetary sphere we have an idea how the immense shear resistance could hold a compressive bias in the entire planetary plate matrix. In this model the compression that resides in the crust at this moment is much older than the mantle displacement period that is currently taking place. The compression that is in the crust right now could be referred to as fossil compression, being that it is supplied by residual or "fossil" gravitational potential energy in the crust that was produced over the last several million years as the mantle subsided during the Pleistocene and Pliocene periods and produced in the crust many of the massive mountain ranges around the world that rose up so quickly during that time period. This process then, that produces this residual and periodic supply of compression in the crust, could be described in the mechanical terms of a reciprocal compressive engine, or even terms describing a mechanically driven gravity actuated drive. This mechanism allows the newest divergent boundary infill to supply a means to periodically advance the plate into a state of compression that ultimately will end in a convergent trench. The plate first being loaded at the divergent boundary when the mantle moves down, and then during the following period of low activity this very laterally concentrated load of compressive energy will slowly redistribute across the plate, and will be largely distributed into, and added with, the overall crustal matrix when the mantle will once again slowly displace outward and again adds another boundary infill for the next round of compression. This process has thus supplied the crust with a net plus of compression, which currently allows us to observe the divergent boundary metrics to be in balance with the convergent boundary metrics, as is shown in the geodetic measurements, all the while holding and keeping the world's mountain ranges from sinking into the mantle. I would ask those in the geologic community to reconsider the standard model once again. Old paradigms must fall for science to progress. I would very much like to discuss this Idea with anyone who is interested. The model can be viewed here; www.electroplatetectonics.com/ Best regards, Marc linquist [e-mail]

Hello pyropulse, thank you for commenting. Well, gravitational potential energy (GPE) is, as you know, a real thing. And as shown in those two references I posted, the oceanic crust is under a massive compressive load. Ghosh et. al gives a revised estimate of it and it does not appear to have a viable source available at our current time and place. Interestingly though, the Himalayas had a surge of rapid growth during a short period beginning several million years ago. citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.728.6975&rep=rep1&type=pdf MOUNTAIN UPLIFT AND THE NEOTECTONIC PERIOD " This uplift of mountains appears to be a global phenomenon. It affects so-called Alpine mountains, mountains on passive continental margins, and those in deep continental interiors. The period of uplift is known as the Neotectonic Period (Morner, 1993; Ollier and Pain, 2000, 2001)." "As an example, consider the timing of uplift in Tibet and its bordering mountains. Gansser (1991) wrote: «... we must realize that the morphogenic phase is not only restricted to the Himalayas but involves the whole Tibetan block. This surprising fact shows that an area of 2500000 km2 has been uplifted 3000-4000 m during Pleistocene time and that this uplift is still going on.» In places the uplift rate is 4.5 mm/yr (five times the maximum in the European Alps). According to Wu et al. (2001) from the Pliocene to the Early Quaternary (5-1.1 Myr) the Kunlun Pass area of the Tibetan Plateau was no more than 1500 m high and was warm and humid. They write: «The extreme geomorphic changes in the Kunlun Pass area reflect an abrupt uplift of the Tibet Plateau during the Early and Middle Pleistocene. The Kunlun-Yellow River tectonic movement occurred 1.1-0.6 Myr.» Zheng et al. (2000) concluded from sediments at the foot of the Kunlun Mountains that uplift began around 4.5 Myr. As you can see Pyropulse, there was a massive expenditure of energy several million years ago "1.1-0.6 Myr.» Zheng et al. (2000)" "Kunlun Mountains that uplift began around 4.5 Myr. " It is my model's contention that the current level of GPE, as noted by Ghosh et. al, and Zuber is simply the residual, or remaining quantity, of that massive expenditure of energy noted above as the Neotectonic Period. "This uplift of mountains appears to be a global phenomenon." It is not easy to distill a 56,519 word hypothesis down to a 1500 word post and maintain its congruity. The model is actually very robust and quite consistent in its abilities to make predictions of observations. Thank you again for your response.

Well done....a different perspective

[@kemitamenophis3221]

With this animation you really get a good picture of how mammals such as Primates and Marsupials spread out from their place of origin and then became separated.

Very very good, and like the time scale below following the evolution... studied this for the last 3 years.. make the IPCC campaign the joke of the centuary ... love the music you added ❤

[@alanjones5639]

This is very nice. Is there a more detailed animation (of larger scale maps) that shows the formation of the Ouachita Mountains, their erosion, and the separation of the Yucatan block? From the last Snowball Earth to Chicxulub impact? Among other things, it would show the source of the Cambrian sandstones that lie on the eroded Grenville at the Llano uplift.

I kept staring at what was to become the place I live in, simultaneously terrified and comforted.

Hi Dr. Scotese, very cool video! Love it. We are using G-Plate for our videos as well. Thanks!

One of my guilty pleasure,,watching our living jewel of a planet wax and wane and listening to classical music!!!!!

[@GumbootZone]

Random trivia: On most maps, the viewpoint or cropping is set so New Zealand is barely visible and in many cases, not there at all.

[@alaneon6456]

I'd like this smooth animation being implemented in Ancient Earth apps soon.

[@abhiramAUS]

Nova Scotia and Scotland were also connencted, neat.

[@ryancormack6934]

Amazing! Thanks for posting this. Would love to see the asteroid that killed the dinosaurs added in a future video.

[@rodgercoman4933]

Amazing. Tells us how insignificant we are in the relative time we currently exist. What will it look like in another 100m years. We float on a sea of magma that will forever define our planet.

Thank you! The land is colored green/brown/white. I thought it was for elevation, or is that based on plant fossil record? Would it be possible that the land was colored differently in the early part of the video? Boy, sure wish I could go back in a time machine and see the earth so long ago.

What strikes me is that virtually the entire continent of Asia has been built up over the last 500 million years. Only Siberia was around in the beginning, about as big as Australia, but now Asia is the largest of the continents!

Marvelous work

[@petergibson2318]

Watching the Iapetus Ocean slam shut to bring together the British isles archipelago is fascinating. Even today the Trilobite fossils in the northern and southern halves of Ireland and Britain are very different. The Trilobites lived on opposite sides of the vast Iapetus Ocean and only the Continental collision which created the Scandinavian and Scottish and Irish and Appellation Mountains brought the fossils together. The Atlantic Ocean opened up many millions of years later. (Iapetus was the father of Atlas after whom the Atlantic Ocean gets its name.)

I have a question. I studied Biodiversity. The age of the rainforest in Malaysia (Malay peninsular) was dated to 130 MYA to 242 MYA. But from.this map why does it show the malay peninsular completely submerged. Or were mountain peak islands /small islands not included in this animation due to lack of data ? Example the Langkawi islands (500MYA) Eastern Johore Basaltic zone (300MYA) Buaya Sangkut Waterfall Basalt / lavaflows (242 MYA)

[@jwilliams221]

Sometimes the data is limited due to area. Some countries have extensive geologic coverage, others don't. I think the lack of complexity of Asia compared to the Americas is due to the scientific capacity of the area. In US, our state GSA have extensive studies. And of course petroleum studies...

[@niueanlaho]

That was just Awesome....be interesting to see the model carry on like another 100,000 years or so into the future after the Neogene period.....
