Genius thankyou!!!
"Out of sequence thrusting." I hate that part. 😂
It is only a theory , correct? The Indian sub continent, lot larger than what we see over ocean, has been traveling for over 40 m years,. Don't know when it contacted Asian plate. One thin sure, when it gets taller the winds and snow above will wear it down just as fast as it grows up, like the alps.
I still can't justify plates moving! The energy required is just not available! And on top of that, every diagram illustrating the movement shows a gradual curve as the plate subducts and the last time I checked, Rock are not elastic! If you bend it, it breaks and therefore is no longer a part of a plate and if one end is being pulled down.... Well it isn't going to be pulling on the rest of the plate! Same goes for what appears to be folded land.... What you should be seeing is shattered rock which should have been happening during the folding process.... But that's not what we see! Everyone always mentions that some mountains are still rising but I have yet to see evidence that they were actually measured by GPS which clearly demonstrates that they are in fact still rising! It's almost like someone somewhere said openly without any evidence that some mountains are possibly still rising and it was just repeated from there even though no one has bothered to take an actual measurement! Maybe a measurement exists? But I'm not aware of it as no one seems to talk about it! Same goes for continental plates! They are supposed to be constantly moving and this is constantly being repeated but no one seems to mention that going by equipment that has been installed between two plates has been checked and found that they are actually either getting closer or further away! I would really love to know the answers to these questions but until I get the answers, I'm going with mountain building being a part and process of volcanism! It's the only process that can be seen that builds mountain's and island's and extended shorelines.... Why earth would need a secondary procedure for mountain building is beyond me!
Florida just banned CWT.
Excellent presentation..
Thanks for the good video. This offers nice clarification of what I learned in my Structural Geology studies about himalyan channel flow
This video was thrust onto me by YT. No resistance to watching was experienced. Thank you. I live next to the Andes where similar processes are at play.
When I was a kid I just knew that there's something called faults and it's somehow related to earthquakes, it wasn't until I watched the movie San Andreas that I had any idea of what faults are. But I had a very basic understanding. Now I know a lot more thanks to your awesome video. Insta subbed!
Very interesting! Well done algorithm, I wasn’t expecting to learn this today.
Thx for the wonderful explanation of how our earth evolves. A full gamet of understanding for young grade schoolers all the way to collegiate studies. Salute for an inspirational job. danke
Посмотрел по диагонали. Моя тема - перикратонные пояса Сибирской платформы. Верхоянье, Саяны, Байкало-Патом. Не увидел у вас обратных надвигов Их роль огромна и сильно недооценена. Поэтому и клин... И надклинный бассейн...
Great review!
Gneiss video, very informative.👍👍
I got your thrust belt, RIGHT HERE!
I've got your critical wedge, right here!
You shot the sea plate moving east at 65 Mm per year with west. Edge of contenant moving at 40 down to almost 0 east ofbthe andies. But is not the south american plate moving west opening the atlantic ocean?
It looks like you’re no longer uploading. Do you have another channel?
I really like your analogy of icebergs. That a bigger/thicker chunk of ice will float higher above the water as appeared to a smaller chunk.
Very well, excellent, and simple way explained
No discussion of the Walker lane? It is going to be the next major fault. As a matter of fact that area yielded the biggest earthquake california has seen In twenty plus years. 7.1m
I live on los andes, this is a perfect paradise for geologists and me. 😎
Great contribution. Very simple and comprehensive way of explaining
Very interesting. If viewers want to understand this in more detail, I suggest they read “Colliding Continents” by Professor Mike Searle. Lots of great diagrams explaining this process
very well explained. thank you!
Thank you so much Sir .U explained it in very easy way.
Would you make a video for new zealand where we Can apply the wedge ?
Very good...
What would this mean for the Houston Magnetic Anamoly?
Geologists only talk and think in millions of years. They have different methods for determining the age of rock layers. However, there is one small problem. Ancient books tell us that a cycle of natural disasters threatens the earth and all living things. The cause of this cycle of disasters is a ninth planet in our solar system orbiting the sun in an eccentric orbit. Features of the natural disaster include a massive tidal wave, flooding, storms, rain, volcanic eruptions, earthquakes, and a fiery asteroid bombardment. That planet is surrounded by a gigantic twisting cloud of dust and meteorites. That cloud obscures the atmosphere, pollutes the water and covers the whole planet Earth with that dust. At the end of the crossing of this planet 9, the earth is covered with a horizontal layer of wet mud, a mixture of sand, clay, lime, fossils of sea and land animals, shells and the deposit of that dust cloud and asteroids. So every layer on our planet contains material with the same antiquity, perhaps many millions of years old: the deposit of extraterrestrial clay. If you don't know about this cycle, you have no idea how our history has evolved. To learn much more about planet 9, the recurring flood cycle and its timeline, the re-creation of civilizations and ancient high technology, read the e-book: "Planet 9 = Nibiru". It can be read on any computer, tablet or smartphone. Search: invisible nibiru 9

Thank you sir for your crystal clear explanation. Many a times, a concept suddenly clicks and everything suddenly makes sense, and that's what happened to me here, so again thank you very much !
I have dealt with convection a fair amount. It is a MINUSCULE force.. That red and blue convection at about 2 minutes - has anyone at ANY time ever tried to quantify the actual forces delivered to the underside of the lithosphere? Vertically? Horizontally? As an engineer I occasionally dealt with convection, and I tell you convection is a VERY WEAK force. In addition, as it rises, it has big time drag with the surrounding fluid. Maybe some people think convection is powerful. I sure as heck don't. In mantle plumes, the convection is a vertical vector. Taking that vertical vector and making a right-angle turn, that is a REALLY inefficient turn, losing MASSIVE mounts of energy. And it takes a unidirectional weak vertical force and spreads it out over 360°. And every time the distance from the plume is doubled, the horizontal force is reduced by D^2. Talk about low psi in the horizontal direction -especially out at a few thousand kms. And THEN they can only apply force by the little boundary layer and the tiny bit of residual drag force there. Every part of this entire hypothesis just screams "INADEQUATE!!". Just from an engineering POV, I have never bought into this. I have always thought they dreamed this up because they didn't have anything better - and they didn't think it through. I just disagree on this entire principle. I worked with forces for 40 years, so I have SOME appreciation for forces. Convection is about the weakest one I know. And they have right-turned convection moving continents. Ay yi yi.
Wegener had a decent glimpse, but what geologists have done with his glimpse is an insult to Wegener. I am of the opinion that he is only possibly 35% possibly right in the first place, though. And the projections back in time to Pangaea? Hey, anyone can make a model do anything they want it to. It's all in the constants, the code and the assumptions.
At 10:00 he mentions the density increase of the descending slab as a "driver of convection". It isn't denser just because of the temperature difference. As it descends and the pressure increases, it undergoes a metamorphic reaction and transforms to denser minerals. It's the descending slab that does the work, not the upwelling mantle.
my brain just shut down
Very well explained, the part on critical taper wedge is really helpful!
Very interesting, although I don't understand how the metamorphic rocks form such thick sequences, when the sand box suggested that they would be repetitive layers.
Thanks tout for the présentation,where Can i find the answser of thé questions
peh
you have no idea how thankful I am to you
It's not Him laya It's Himalaya!
Best is this only.thnx.
I'm so happy I found this video😃❤❤❤Thanks man
Thanks sir for explaining so beautifully....I have learned a lot from this.....Please make some more videos on different models of formation of Himalaya or please suggest me; which videos or books I can follow.... Thank you!!!!
Totally sucks
This video was immensely helpful! Thanks so much and keep up the great geology content :)
14He are not daughter isotopes, only alpha decay particles.
Subbed, exactly what I was looking for!
I love this channel
Oh gad yes 💦
Plz make vedio of other thermochronology tools I’m waiting
