Editorial Notes:
I probably have to address a thing that was mentioned a lot in the comments and that is the hypothesis that asteroid impacts have caused flood basalt eruptions. It usually goes something like: a large-body impact can trigger flood basalt volcanism antipodally (on the opposite site of the earth) because the seismic waves caused by the impact are focussed there.
This hypothesis garnered attention in 90s when the mantle plume model wasn’t yet so widely accepted and before we knew much about the formation of these provinces. Since then, however, there wasn’t any major breakthrough or even progress in confirming this hypothesis.
We don’t need an outside force to explain and model LIPs and to this day we haven’t found a single convincing example of a crater that can be linked to the formation of flood volcanism. The 3 most quoted crater from the comments are Bedout - which was originally dated to be around 250 mya and supposed to have caused the Siberian traps. This dating is however controversial and it probably isn’t even an impact crater. The Wilkes Land crater in Antarctica - which was also dated to be some 250 million years old - isn’t any more convincing either and the last serious papers making a connection between this theoretical impact crater and the end Permian extinction is I think from the late 90s. Lastly there is the Chicxulub impact which as we have discussed definitely didn’t cause the Deccan traps. Plus, it wasn’t even antipodal to begin with.
That we havnt found any good examples isnt really surprising since models have shown that is very unlikely that the impact of even a large asteroid would be seismically powerful enough to cause such a phenomenon on its own. That’s why this hypothesis is seen (at best) as controversial today and why I didn’t talk about it in the video. But since this popped up so much in the comments I thought I still address it.
The only hypothesis that is still discussed and backed at least by some evidence is that the Chicxulub impact worsened the Deccan traps volcanism based on the fact that some 70% of the lavas were expelled after the impact. This can of course simply be a coincidence but it’s also not hard to imagine that if there already was an enormous amount of magma trapped close to the surface produced by a mantle plume the seismic waves caused by a large impact could have certainly freed them. So this hypethesis is, I think, far easier to get behind.
The Ends of the World by Peter Brannen (www.goodreads.com/book/show/32075449-the-ends-of-the-world) is a very informative and easy to read book on this subject

Woah
Yes, and it's one persons science, for him to make assumptions on behalf of the global science community is a little presumptuous. Asteroids rarely impact perpendicular to our planet therefore antipodeal points are misleading, and the speed at which the shock wave travels requires some serious maths, I'll sit on the fence until more science is proven with global consensus.

Cyrille Yukimaru And it’s one one guy!
The documentary channels are mostly fluff!
Yep. Even the clipped and ( to some) somewhat pedantic sounding German accent enhances the gravitas, import and exactness of what is conveyed.
Hes done his research too. I research Large Igneous Provinces (primarily the Ontong Java Plateau) and he did a great job of sticking to the facts. These super volcanoes are very easy to sensationalize.
@@KelGangi Are LIPs routinely classified as super volcanoes? I understand that the mantel plumes that create LIPs seem to have some association with super volcanoes, but do they always? For instance, is Toba or Taupo the result of the remnants of mantel plumes, or are they just really large conventional volcanoes?
Simply brilliant: as a now retired scientist intimately interested in LIP events, extinctions and the break-up of gondwana, you have (in my opinion) simply nailed it! Too often earth scientists appear to lose sight of the fundamentals of "cause & effect" and instead tend to support more exotic possibilities! Your breadth of knowledge across quite a number of different (but related) sciences is equally amazing! Cheers from Down Under and keep up the exceptionally great work.
Personally I never quite bought the single asteroid killed the dinos hypothesis. The earth is pretty good at burying, stabilizing and normalizing quickly after single events like that. Particularly when you have the Traps as a viable explanation, it just seems a tad far-fetched. Almost as if someone who has watched too many movies came up with it.
But, to quote Paul Feyerabend: "Change only occurs at funerals". We probably have to wait for the comet people to all die before this particular paradigm can change.
@@politicallycorrectredskin796 I don't think you realize how great an impact it was.
Glass from the impact has been found all the way across the world. It literally rained molten glass.
@@ayushsharma8804 Yes, but in geological terms it was a very short event. Almost literally hide in a cave for a few months and you'll be fine, which every animal that has ever lived has been very good at. I have yet to see any evidence that an impact of this kind, short of the one that possibly made the Moon, would be able to wipe out an entire group of animals.
Meanwhile there is copious evidence that long-lasting basalt flows do cause mass extinctions, and one such basalt flow was open at this exact time in India.
If you find a corpse with a knife in its back, you probably should be looking for someone with a hand, most likely a human of some sort. The killer is unlikely to be the parrot sitting in the cage next to the corpse. Parrots don't have hands, so can't easily wield knives. More importantly, we have no evidence of parrots ever stabbing anyone before. The Impact Hypthesis is a very unpromising angle that I suspect is only relevant because someone somewhere once needed a PhD, and had to cook up some random stuff no one had talked about before because it was ridiculous. This is how mass "science" works now. Anything at all that hasn't been talked about before, which as you can imagine is an ever-shrinking category of increasingly absurd things.
To me, the Impact Hypothesis is people handwaving away reasonable objections by emphasizing the size of the parrot. Polly was very large and aggressive you see, so that's how come she stabbed someone in the back.
@@politicallycorrectredskin796 yes but the temperature reached 400 C, that is know because if that wasn't true it would violate conservation of energy. It would not take millenia to clear out the megafauna this way.
Also maybe you are forgetting that the KT boundary exists.
It is simply too big a coincidence that the large shift in the fossil record coincides with this sharply defined boundary, there also a small period of explosive fungal growth following the KT boundary.
Also there is the fact that it might as well have caused global cooling over a period of tens of thousands of years. It cleared out 60 cubic kilometers of rocks, that's a lot of sulphur dioxide.
The Deccan traps had been going on for 5 million years at this point and there was hardly a bump in biodiversity until the KT boundary, it is simply undeniable that the Chixxulub impact is involved in some way.
@@ayushsharma8804 But it didn't wipe out the fauna. Reptiles, amphibians, mammals, birds, fish, invertebrates and insects survived just fine. It wasn't just big dinosaurs that got wiped out. All of them did including the aquatic ones, while essentially no other group of animals was wiped out.
Evidence from China even suggests that dinosaurs were at least partly covered in feathers, so it can't be the cold either. Feathers are the explanation for why birds survived. If that is the case it should have worked equally well for the dinosaurs.
This hypothesis is full of holes. Repeating it over and over doesn't make a mistake more true or not a mistake. If you have to rely on ad hocs and maybes you don't have a scientific theory. You have the concept of a novel. First of all you have to explain why Chixulub killed ALL of the dinosaurs and ONLY the dinosaurs. And there is no credible way to do that. The more extreme you try to make the impact, the more implausible it becomes that EVERYTHING except the dinosaurs survived. The more you downplay it the less likely it seems that it could have killed anything. Why for example did the pleiosaurs go extinct at the same time? They were fully aquatic and should have been perfectly safe, like turtles and crocodiles apparently were. But they weren't for some reason. All the aquatic dinosaurs died out too.
Meanwhile the Deccan Traps were open, the biggest known killer in geological history. We even know from the bigger Siberian traps that chemistry from those things can take millions of years to build up to a critical level and then everything collapses very quickly as the oceans react to it and acidifies and deoxydizes. Just because it had been open for a long time is no argument. Maybe it reached a critical point that changed the atmospheric chemistry just enough to wipe out the dinosaurs and then close or something. A sort of miniature End-Permian episode that was just big enough to get all the dinosaurs but not everything else. There is no mechanism in a crude impact scenario that can account for the highly targeted extinction. An impact doesn't universally change atmospheric chemistry, just temperature. Very hot then very cold for a few years. Very few in geological time. And you would need a universal change that only affected dinosaurs. That has been the problem all along. I see at least the potential with basalt flows. Not with impacts.
As a geologist, this is really an amazing video.
Despite being fond of science, I always used to think of Geology as a boring topic due to the incredibly long time frames involved. Having learned a little about it, I must confess that you guys quite literally rock ;)
Hellloww fellow colleague :)
@@arthipex8512 the geologic time scale is super interesting. As geologists, we have to think of a million years as almost nothing in the grand scheme.
@@meredithmcmahon6239 Yes, I was underestimating that. As an engineer, I'm used to seeing results within years at worst. Seeing results after millions of years without the option of tinkering with it seems frustrating to me at first. Still, my electrical engineering seems puny in comparison when considering the staggering forces involved in your profession.
I think what makes his videos great is that people like me who doesnt have a degree on science or engineering can comprehend simplified versions of these otherwise complex concepts
It’s finally done ... Had to rewrite some parts a few time that’s why it took longer than usual.
Technically I even have enough material for a third part but given that I’ve now done everything I originally wanted to do with this topic I think I’m going to leave it at that - for now.
Yay, hopefully we won't die from volcanoes, even doe Yellowstone might end our careers of living.
If you have enough for a third episode please make the third!
Excited for part 3
I want a third part! I wanna keep up to date on this science!
What's the gist of that third part material?
“Asteroids certainly had a massive impact on this planet”
Nice pun
And a “heated debate”
Someone explain me the impact of lunar lake meteor so that we could try to relate it with human civilizations.
Only that isn't what he said. ... he said _"important"_ not _"massive"_
see 12:58 for yourself
@PC Random Who says there was only one Theia ?
We're "spinning and spiraling through space" at mind-boggling speeds and yet the impacts never come in at an angle ... they manage to splat straight down every time... science is mind-blowing, isn''t it?
"The exact processes are still up for heated debate."
nice :D
"HEATED" debate~

When i was kid, everytime 'Mass Extinction' mentioned in science show i thought it happens in few weeks/months.
Now i understand it take hundreds or even thousands of years.
Not necessarily lol. Could be in one day. One very, very bad day.
@I'm Still Alive That was a "misunderstanding" blown up in certain mainstream media related to a upcoming close encounter with a Near Earth Asteroid
Yeah though it should be noted that the Asteroid component of the K-Pg extinction was sudden and catastrophic and resulted in a order of magnitude increase in Eruption intensity in the Deccan Traps. There is strong and increasing evidence that mass extinctions occur when a long term ecological stressor coincides with a relatively sudden pulse factor driving the system over the edge.
For the End Permian as was mentioned in Part one the sudden trigger was the rapid release of sequestered carbon from the Carboniferous Period. Though a 9 million year Earlier flood basalt and the continued existence of Pangaea were likely the main stressor.
The PETM likely was similar with multiple flood basalt eruptions one of which brought a heavier blow by erupting underneath oil rich layers, and this video already addressed the End Triassic and Devonian extinctions.
The Ordovician is trickier than other extinctions as we have no direct evidence for the cause aside from increased mercury levels and extreme shifts in sea levels. Though a recent paper in Science Advances may have partially resolved that by providing quite strong evidence that the sudden onset of the Ordovician ice ages and associated extinction was likely driven by a cataclysmic break up of the 150Km L Chondrite parent body in the Asteroid belt around 466 Mya according to shacked quartz dating within L chondrites, abnormal 3 fold increase in fossilized meteorites almost all of which were L Chondrites and isotopic abundances of clearly astrophysical element isotopes namely Helium 3 and Osmium. This impact likely formed a massive cloud of debris which drifted into the inner solar system blocking out enough sunlight to dim the sun for around a few million years.
advances.sciencemag.org/content/5/9/eaax4184 (It is open access) Throw a Flood Basalt on top of that and you have a catastrophic driver for extinction, (Though given that Mercury levels, on top of carbon isotope fluctuations among other things, are usually the hallmark of extinction events comparisons will likely be needed to check whether the mercury spike corresponds with the spike in Helium 3 and Osmium found in the above paper)
Perhaps the most interesting of LIP induced cataclysm was the Franklin Large Igneous Province which coincided with the Break up of the super continent Rodinia and its associated role in at least the onset of the Sturtian phase of the Neoprotozoic Snowball Earth
Teguh Lumban-Gaol I feel bad for our future generations. Hopefully it won’t be too bad. Mother please be kind to thee children for thee I repent their sins.
MaskHero Zo, depending on how old you are, you may still be alive when the shit hits the fan. We’re releasing sequestered ancient carbon stores in a geologic instant, just like the Siberian Traps did when they hit seams of buried coal. It probably won’t start getting really bad for at least another half century, though, unless we actually get our collective acts together and do something about it. Then it won’t be quite as bad.
Getting hit by asteroid, and then smoked by Deccan Traps eruption, bad day for dinosaur.
🦖
Reiterate that over geologic time those two happening simultaneously seems statistically unlikely to a massive degree (sample size problem).
If it has happend before,it can happen again;they don't call it "Armagheddon" the end of all things,for nothing.
@@peterjamesfoote3964 The Deccan traps eruption,lasted for roughly 5 million years;leading up to the asteroid impact 67.5 million years ago;according to
Paeolontologists,geologists,
geophysicists,and astrophysicists.According to scientists;within the scientific community,the cause of the dinosaurs extinction,was the flood basalt eruption;of the Deccan traps igneous province.That would mean that the asteroid impact, occurred long after;the dinosaurs went extinct.Most of the terrestrial and aquatic survivors,of the igneous province eruption;of the Deccan traps,were finished off by the 7.5 mile wide asteroid;as only a few species survived the extinction event.The pattern of history is repetitive;meaning that it rymes,and mirrors itself.
It has happened before,and it will happen again.Only this time,much of life on the planet;as we know it today,will not survive the extiction;that will rival the end Permian extinction,also known as "the great dying".
Devin Russell that is not exactly correct, we are currently evaluating fossils found inside the boundary layer. Clearly showing dinosaurs could still very much alive when the body hit Mexico and survived shortly afterward.
Wow! Never occurred to me that Hawaii is a remnant of a mantle plume! And I was always under the impression Iceland is just a result of the Mid-Atlantic divergent boundary! Learning something new is nice :)
Hawaii is an active mantle plume.
Atlantic? A bit off...
@@shebbs1 Iceland is in the Atlantic Ocean.
@@AtarahDerek True, but you did mention Hawaii.
@@shebbs1 The OP did not say Hawaii was on the Mid-Atlantic Ridge. They said that Iceland is, which is correct. What the OP did say was that Hawaii was on an *old and inactive* mantle plume, which is incorrect. The Hawaiian hotspot is still active, meaning the mantle plume beneath it is as well, albeit not as active as in the past.
Absolutely fascinating. Thank you so much for your hard work.
As a child I wanted to become a vulcanologist, but got tripped-up by something easier to get into (in England) - electronics. I am in my late 50s now, but my interest in the Earth Sciences has never waned. You sir, are keeping my interest alive. I applaud your efforts. 💖
Thanks for that lovely comment.
I wanted to be a volcanologist, too, but I would have had to take physical chemistry with a professor I’m sure was Satan on his spare time.

It’s a shame that this channel doesn’t have at least one million subscribers. Great work mate, can’t wait for the next upload.
this makes me very curious about volcanism on other planets and moons. like mars with its 21km tall olympus mons, or io, the moon made of hellscape
well, mars does not have any volcanoes anymore, but yeah it most surely had some big once, once.
It seems like mars had mantle plume volcanism, but not plate tectonics, which is why Olympus Mons is the tallest mountain in the solar system: it's the result of millions of years of eruptions in one place. Theres lots of evidence of flood basalt across the solar system, the moon's maria for instance, but moving and subduction of plates seems fairly unique to earth.
@@atonal440 exactly this with also factors of there >>probably
They're extinct, and it never eroded down because Mars' atmosphere is too thin to form particularly strong wind, and there's very little liquid water to chemically weather anything.
Io is a very weird case. It's actually best described as external volcanism. Essentially, Io is really close to Jupiter, which has a powerful gravitational field, so Io is endlessly being pushed and pulled around, which through friction is at least partly responsible for its molten interior. The rest then works more or less like earth, but Jupiter also likely warps, bends and breaks Io's crust somewhat, causing more cracks and fractures for magma to seep into.
14:43 - I think you meant to say that "humans and all other animals alive today are the *_descendants_* of..."
But the ending scene at 14:56 was ... thought-provoking.
As a second year Geology student, I can safely say you have done a fantastic job producing this video essay, keep it up!
I really appreciate the level of detail you've included for each geologic boundary event. This is one of the first times I've ever seen the pripyat-dnieper-donets rift or viluy traps mentioned outside of a textbook. You're an excellent science communicator!

Well apparently that changes in a few hundred years when anti-matter weapons become a thing.
Absolutely brilliant! This is not my introduction to the concept of Mantle Plumes and flood basalts but the visual aids really help cement that knowledge. Something I had _not_ come across before and which does give me much pause for thought is the straight-line link between current-day 'hotspots' and flood bassalt provinces of the past. That is fascinating. The inevitable end result of this presentation is the consideration of where the next plume will strike--if it hasn't already and is merely right now making its way through the shockingly thin crust... I think these events are almost certainly a factor present in The Great Filter.
I love smart people who’re able to make complex subjects easy to understand for dummies like me 🤪
Keep up the brilliant work

"You're just wasting time"
"No dude, I NEED to learn about mantle plumes... otherwise, how will I know?"
essentially all i learned is the earth has a giant omni directional lava lamp living in the center of it... and that is cosmically DOPE!
It's an interesting way to look at it, but looking at the full geological process and taking into account smaller pieces of it, such as the carbon cycle or silt depositing, and even the subduction zone process shown, it really is a full cycle lava lamp. Convection is essentially a constant on our planet , which is still dope
Earth has a giant omni directional lava lamp living in the center of it that may someday KILL US ALL
@@Gregbot9000 ALL HAIL THE OMNIDIRECTIONAL LAVA LAMP
@@Gregbot9000 When the Earth's core finally cools and becomes solid, the Earth's magnetic field will go away, effectively leaving our atmosphere naked and completely vulnerable to the sun's destructive solar winds. This will have the result of most of our atmosphere being blown out into space. This is what many scientists think happened to Mars to make it a barren wasteland. So yes, someday the core may kill us all.

Well done, really well made video. I don't really know what to say as creative criticism on this video. I think that this video is VERY informative whilst still being fun to watch.
One of the reasons why this is. Is probably due to the fact that you as you said "this a simplified view of the process, the reality is much more complex. But it gives us at least a basic understaning for why and how these massive eruption have occurred.".
This was a very well made decision due to the fact that it would be VERY "daring" to make a complex video about a topic that(let's be honest here)not a lot of people know much of, including me.

Something about that intro screams Kurzgesagt...
...the visuals, the editing, the script...
You're not the only one who can't get enough of it.
Hands down one of the best videos I've seen on youtube
So what I’ve learned is: don’t throw ice cubes in lava
The flood basalt that covers Brazil, Argentina, Uruguay and two other African countries was missing and was considered a very large spill that was not mentioned in the video.
It's so incredible how our planet is really just a droplet of molten magma in the midde of space, and we are just mold on top of the bubbling slag!
IMO the best presentation of Mantle Plume events over the last 450 million years. Worth watching both parts!
There's an amazing theory out there which is fast gaining evidence that the Chicxulub impact might have actually been directly responsible for the huge scale of the eruptions in the Deccan traps. The eruptions were happening there long before the asteroid impact, but only after that did it become the largest flood basalt in history, second only to the Siberian traps. There seems to be a period of dramatic jumps in eruption rates right at the KT boundary, which if true would rule out coincidence very thoroughly for the two events. When the asteroid hit, it's said to have "rang the earth like a bell" with an earthquake of magnitude 10 or more everywhere on the planet. This would be more than enough set off volcanoes all around the globe, not just in the Deccan traps, and there is indeed some studies that claims of this happening along oceanic ridges at the time.
Either way, it just makes sense that there was some sort of causal connection between the 2 events. Because if it wasn't, then the dinosaurs were just uncannily unlucky to have had 2 catastrophic events line up perfectly for them to experience at the same time. Perhaps if the asteroid never hit then the eruptions would've died down and it would've just been another smaller scale flood basalt that life wouldn't be dented significantly by at all. Maybe if the Asteroid hit at a time when the eruptions weren't happening, then we would only get very small borderline mass extinction that wouldn't have been strong enough to kill off all the non avian dinosaurs. It'll be awesome to see what studies into this actually turn up in the next few years.
There were a few flood basalt eruptions that were significantly larger - not just the Siberian traps. Other than that you're right - this is a discussed hypothesis. I addressed this in the pinned comment.
@@factsinmotion3978 Maybe the asteroid sent a huge shock wave through the core, causing it to well up on the other side
@@everettduncan7543 The hypothesis is that a large impact is something like a M12+ earthquake, that sends shock waves around the Earth's crust (along the outside, not through the interior). They converge at the antipodal point, shattering the crust and enhance or even create a major volcanic zone. Some geologists go so far as to propose that almost all hot spots are the (initial) result of a major impact on the opposite side of the Earth. With millions of years of plate movement and the rapid weathering or subduction of impact craters, though, it's hard to tie together specific craters and hot spots, although Chicxulub and the Deccan traps seem a good bet.
I read the exact same research.....I too, think it’s very very compelling.
This conversation has peaked my interest into that research where can one find it
"This is still a heated debate"
Nice pun
Also "Asteroid impacts certainly had an important impact on the planet"
I've spent the last several weeks learning about magma and the formation of plates, mountains, etc, and this video explains much of what I learned, and then some! An excellent overview of the subject.
I'm convinced that there are people whos soul purpose is to dislike videos, regardless of the content. Awesome video man, thank you!
14:30 - 14:40 - that was a beautiful transition!
"Heated debate" "Deeper Origins" Important impact"
What an incredible video. It's not easy to take such a complex topic and explain it in a way that still retains much of the nuance while remaining accessible to intelligent but non-geologist audiences. Presentation of various hypotheses and theories shed light into the scientific state of the field and what is still left to better understand. Moreover the narrative structure, of starting with the Siberian traps example in Part 1 and then moving on to illustrate their cause, relationship with hotspots, and correlation with extinction events in Part 2, kept me engaged with one "no way!" revelation after another. I can't believe the animation is done by the same person who researches and writes the script!
I would just like to say this: FIM, your channel, over the last 2 years, has become my favorite channel on RUclips, and many of my favorite videos are the ones you've done. I love you, and would like to have your internet babies. Lol
Sidenote: Been telling all my friends and family about you since 2019. Keep up the great work! Please!
Thanks! Very much appriciated it.
"The exact processes are of course still subject to HEATED debate"
No kidding :D
So much for "Death from Above" as well as the concept of "Standing on Solid Ground"!
The visually clearest explanation of this process that I've seen....well done, and thank you!
I stand stunned and in awe. This video is not simply the best one I have seen about this topic. On top of it, it ia done by one person! Dude, whatever you do in "real life" to earn your living - THIS is worth a bundle! Watching this video, for the first time I was not annoyed by commercials, because I think it is worth every cent you gain through them.
Thanks! I appreciate it
12:30 although a lava province no longer exists
"looks at Hawaiian hotspot"
These eruptions give me the same sence of impending horror as H. P. Lovecraft stories, except this is worse because it can and will happen again.
Impending doom approaches…
Thinking that the dinosaurs went extinct 65 million years ago puts into perspective how slow these processes really are.
Makes evolution seem fast.
Another channel that teaches us more in 16 minutes than our school teachers manage to do in years. Thank you so much for this terrific video. Keep up the good work.
I as a geologist approve of this video! Keep up the good work.
I am surprised by the amount and quality of information in the video. This is one of the best on this topic. I live near the Ural mountains and there are sometimes small earthquakes here. A couple of years ago it was near the city of Chelyabinsk (yes, this is the city where the meteorite fell, lol). I could not understand for what reason these earthquakes were. Now it is clear, holy shit..., below us is the remnant of the plume that caused the most massive extinction.
This channel is criminally underrated
I'm definitely a proponent of the idea that the late-Cretaceous extinction was a two-punch event of both the Deccan Traps and the Asteroid impact.
Me too! Tbh until recently I attributed more the cause to the asteroid, but after reading upore on this the Deccan Traps theory as the main contributor makes more sense. But it probably didn't help a lot that half of the planet's surface was superheated briefly and frozen over due to the asteroid's impact, on top of all the other major changes the Deccan Traps were producing with its emissions. Life after all is a system, and like any system there are tipping points, if the traps by themselves weren't enough, adding a cataclysmic asteroid in the mix probably went and did it.
Hello people of the future.
La Palma volcano 🌋 killed us all!
We have a volcano called Mount Paektu where my father was born. It’s beautiful
Beautiful mountain with a beautiful crater lake. Also very much capable of VEI 7 eruptions. Speaking of which does anybody have any good resources of how Mt. Paektu /Changbaishan formed on the border of China and N.Korea? It's not really close enough to be part of the Ring of Fire and no clear rift connection or known hotspots etc.
Thank you Kim, very cool!
@@Arthion This video by Deep Dive addresses that question of how the mountain is connected to the Pacific Plate: ruclips.net/video/3C2HVOB-g5s/видео.html . The mountain is not connected to a hotspot from a mantle plume. At the very end that video suggests that the mountain is not a unique case, but rather the mechanism that created it may share a connection with flood basalts, and implies that continental flood basalts (as opposed to oceanic ones) may have a subduction-related origin rather than arising from mantle plumes. It does not go into any detail at all about this, but just like with the current video, there are some links to scientific papers in the description. If I had more time and knowledge it would be interesting to read these papers to explore how to reconcile the viewpoints in these two videos.
@@damagepatrol Thank you very much. I did stumble upon that video though a month or two ago :)
This taught be more about volcanos in general than school did. *APPRECIATION INTENSIFIES*
I just wanted to add my voice as one of those who appreciate the truly excellent quality of the content on this channel. It’s no exaggeration to say I value this channel more than any other on RUclips, maybe Isaac Arthur is close but he is generally considering the absurd places we can go in our future whereas this channel is talking about the realities of now which I value more. Thank you again, you are truly an under appreciated talent. I hope you get all the subscribers you deserve.
Thanks for this lovely comment
"asteroids certainly had an important impact on this planet"
"pun" intended? lol
Love this planet! Its so amazing complex and beautiful. A jewel in a ocean of darkness.
You really have to appreciate just how interesting the science behind volcanos is.
Confirming several of my thoughts and dispelling others. Into the bargain the presentation is first class.
My thanks squire.
Me: listening to music from my favorite artist
Also me seeing this video: Hold my beer
So... Like... A lava lamp?
I'll see myself out
Your quality is on par with Kurzgezagt, and to be honest as an Irishman I prefer your accent. Seriously amazing stuff bro 10/10
EXQUISITE quality of production, design and writing! I especially appreciated those few hidden puns :-) You deserve all the success you have!
I was actually wondering if this video would ever come, and it just so happens to come out 20 minutes afterwards. Coincidence? Maybe.
Hotel? Trivago.
No, please noo
I'd love to see you make more videos about paleontology and geology in general. There a chance we could get a video on the process of fossilization in the future?
By far the most refreshing educational connect I've seen for a while
In this one video alone I'm very much convinced how mass extinctions have happened. Also the the formation of the country I live in. Thank u.
Imagine if a supervolcano erupted right now, most of us would die and the few thousand people that would have to repopulate the earth would be left with literally too much knowledge to spread again, so much would be lost...
especially all those memes. what a tragedy this would be.
Good.
@@factsinmotion3978 They could be recovered from the Norwegian Global Meme Vault, buried deep within a mountain
Eh, unless more then one supervolcano erupts at the same time things would be rather shitty for a while but nowhere near only a few thousand people left.
@Gary Oak That thing that never happened?
