Just as an idea, you might follow up with the very spiffy physics and engineering that let us establish the velocity of convection currents in the mantle using seismographic equipment. As long as I'm bothering Henry about it, I may as well bother you, too. Loving your most recent material!
That does nothing to explain the more than 100 million cubic miles of consecutive layers of water deposited sediments over a mile deep around the world that buried samples of everything that was living on earth at the time. You people are fed a bunch of garbage and you eat it up.
You kind of made it seem as if the ocean crust dives under continental crust because continental crust is thicker. It would have been nice to hear that the ocean crust is far denser, and when it pushes up against continental crust, the denser material is forced under. Nitpicking point, and a great video overall.
He didn't really comment on it so I doubt many people even thought about it (myself included ;) ). I think it's just a relevant thing that could have been said but it probably didn't mislead anyone.
Too add as well, usually you'd find more volatile volcanic activity at these subduction zones due to the crust displacing magma and forcing it upwards to eventually for composite volcanoes.
Eemeli Bergström you wouldnt notice, this would happen over 250 million years not a day. the map printers would simply move how the map looks by like 1 cm every million years or something of the sort
I heard that super-continents are actually bad news for life. Seas and oceans act as climate moderators, so we experience moderate climate. Super continents on the other hand will bring in extreme weather (i.e. extremely cold winters and scorching hot summers). But this is stock knowledge, so I'm not so sure. :/
I really love how you explained all of this :) and the drawing/animation is really creative xD! (like how the plate tectonics are "moving itself") I really hope your channels get alot of supports and subscribers!
this changed my life, when i watched it on full volume i didnt hear my dad screaming in the other room if i wasnt watching this he could still be alive :_:
I did not expect to learn something new here as I thought I had a pretty solid handle on how this all worked. I was (as is often the case with videos produced by Henry Reich) wrong. You should watch this, I'm sure you'll learn SOMETHING
Man, I searched about this in about 3~ 4 books, It was all getting over my head. I couldn't understand that if tectonic plates moves then how the hell continents can merge and devide, But a simple example of conveyer belt solved it all in second ❤️ thanks a lot
The thinner plate doesn't sink. it's the denser plate that sinks. The oceanic crust is denser than the continental crust and that is why we see trenches only underwater.
This is a really really well explained video, thank you so much!! the way you described the mechanics of how it all works is the best that I have ever heard.
This is just an average of all movement. But if it really moves, it moves really fast. In some worst cases many metres in a split second. This is what we call earthquake.
*This is completely false.* Plate tectonics are a secondary effect of expert teams of geologists going into the mantle using nuclear powered trains made out of a material that converts heat energy into structural strength, headed by a laser/vibration generator that will liquefy and blast away rock in front of the train. Once the train is deep enough, a series of thermonuclear bombs are released and timed precisely as to cause a massive wave that keeps the core spinning at precisely the right speed. Please next time don't spread ignorance around, every serious geologist knows this. In fact its even hidden in most books about this: "most of the energy in the earth's core is generated through nuclear fission". Next time do your research and do it right.
Jacob Furrow Well really for a Hollywood movie it had a good bit of physics, I mean the fundamental idea of generating a spin flow of the core with precisely timed warheads isn't completely out of town if you believe in the current most widely accepted theory on the nature of the earth's inner structure which is sadly taught as a fact while really it's just a theory much like a lot of other things in today's scientific community. I watched the movie when I was about 12 or 13 and haven't watched it since so I can't tell you for the corniness, but at least its a good Hollywood movie for children interested in science. I just found a really good movie on youtube by the way on crime and gangs, its quite beautiful, sort of like American history X for black gangs (which if you haven't watched, you should, it will really move you), just type South Central 1992 HD 1080P FULL on youtube, and give feedback if you do check it out.
shist thats gneis Geologists yay! I just like to mention, cause its easily misunderstood when talking about "flowing" plates etc. The mantel is not liquid, only the outer core is liquid, the rest is solid. Tho every medium has some viscosity to it wich makes the "flow" possible.
I haven’t paid attention in science class for the past month (the teacher is boring and I’m sitting next to my best friend). I now know practically everything I missed from a two minute video.
Can you please please do about tectonic boundaries, an example of where they can be found in the world and what land formations and events can be found there? Love your videos ^_^
Was looking for a video about tectonics. Didnt find anyone especially good... except for this one! Very pedagogic, awesome. I only wish it was longer. :) Cheers!
Yes, once the dinosaurs died out and stopped pooping into volcano craters, there wasn't enough matter being deposited to sustain the earth-swelling process. But TH-cam comments may be a promising new source of shit.
Fun Fact: The oil that we drill out of the ground is actually what causes the tectonic plates to move smoothly otherwise there would be too much friction and the plates would not move.
You're partly right The earth is a cube, so while it may seem flat at any given part, there are 5 other "flat" parts as well. God lives inside of it, hell is in space.
I literally just learned about this in school and already took extensive notes on it and only missed one question on a 30 or so question test, but I want to write really fancy aesthetic notes on the topic because I'm bored, so I'm watching this to do it because I don't have my binder with all of my papers and stuff in it
I spent too much of my life understanding the process, but unable to visualize. Thank you! This knowledge feels much more grounded in reality now. (No pun intended)
two points: 1. oceanic crust (basaltic) goes under the continental crust (granitic) because it's denser, not because it's thinner. 2. Google Earth is either upside down according to its rotational direction OR it's spinning in the wrong direction if the orientation of its axis was intentionally placed with the South Pole in the "up" position.
super job. A bit fast, but really liked it. I will show this to my 7th grade science students. :) My favorite part was the crust breaking off.. and the suction.. and the continents ARE baggage. Do more!
Great video!!!!! I am in school and learning science, I am definitely going to start watching these. Very cute and helpful!!!!! 💖🥰 Grabs my attention very well.
Correction 1:20 it is not the thinner of the two plates, it is the denser of the two. Continental rocks are made up of felsic and intermediate rocks (High Silicate%, low Fe+Mg content), which are less dense than the Ultramafic mantle (very high Fe+Mg content). That's why continents are ontop of the mantle. Oceanic plates are made up of mafic material (high Fe+Mg content, less than the mantle, more than continental crust). So when an Oceanic plate and a Continetal plate collide, the Oceanic plate subducts (goes under) the continent, because it is more dense. When it is an Oceanic-Oceanic setting. It is still the denser of the two plates. When something cools, the material becomes more dense. The same applies to oceans. So the older therefore colder therefore denser oceanic plate subducts. So it becomes a matter of how far the plate is from the Ocean Ridge, so if plate x and y collide, and plate x is further from the ocean ridge than plate y, plate x will subduct under plate y. ------------------------------------------------------------------------------------------------------------------------------ Also the main reason for plate movement is Ecolgite formation. This forms at 45km depth, and is much denser than the surrounding mantle. This is what pulls the slab down the most. ------------------------------------------------------------------------------------------------------------------------------ The general idea is correct, but it isn't for the exact reasons you stated. (I'm studying geology at University, we do not know all the answers and hypotheses are always being improved, but the above is the recent info on it)
What happens to the pieces that break off? Does it mean that the earth is constantly becoming smaller? Or is there some way the plates "grow" and thus keeping everything balanced? Thanks in advance
I may be a little late, but the ocean crusts that sink, sink so low that they eventually melt by the heat. Then, when plates move away from eachother, there is a "gap" in between the two plates, as you saw in the video. Then a vulcano can appear or magma just flows to the surface. That lava eventually hardens which creates a new piece to the ocean crust. It's basically a recycling cycle :D (This was pretty hard to explain in English😅 I hope it's clear/correct)
The Lower 48 U.S. States are not considered by most a continent. However some definitions do agree that Australia is a continent of which I disagree. But overall a great video!
What happens if a plate completely sinks and breaks off under another plate into the mantle? Is there just a big gaping hole where you can see mantle? Or are there new plates that form?
I think the subducting plate is going under at an angle less than 90 degrees so you wouldn't see what is underneath entirely, jus deep trenches (still part of the earth's crust). And yeah, once a plate had completely subducted, new material would've been created on the other side. :)
Amanda Cheng As others have said, younger crustal material is generated on the divergent side of the subducting plate. Assuming rifting is occurring at a greater or equal rate to subduction, the plate will not be completely consumed. On the convergent side, the subducting slab can extend hundreds of kilometers below the surface and ocean sediments are compressed into an accretionary prism filling the basin created by the continental and oceanic plate convergence. So no, there is no place were you can view the mantle. There are places were you can view crystallized mantle material. shaenhyun Yes, the subduction angle is less than 90 degrees. The angle is controlled by the relative rate of subduction, which is usually associated with the process occurring in the backarc (the basin on the opposite side of subduction). Slower subduction produces a shallower angle. Compression (causing slower relative subjection rates) in the backarc produces a shallower angle than extension (causing faster relative subduction rates).
Studying for an exam using old tests, one of the questions was about plate boundaries. Hilariously, I tried to remember 8th grade science before trying to remember freshman year geology. Still, this was a nice refresher.
Does the oceanic plate subduct because it is thinner than the continental plate, or is it more to do with density? The video seemed to suggest the former rather than the later.
Great video! Very cute drawing. I wish you made this video in my freshman year taking intro to geology. I would've appreciated the subject more. And also I would've loved it if you added something more about how converging plates can create mountains and volcanoes, and how diverging plates create new crust material on the ocean floor. Other than that this video is awesomely cute.
thanks for teaching me something in 2 minutes my teacher took 2 weeks to teach
This is so true it's funny.
👍
Lmao
Tooo truu
ya and he explained it better
A Wilk lol true
Great video! I definitely learned something here.
Just as an idea, you might follow up with the very spiffy physics and engineering that let us establish the velocity of convection currents in the mantle using seismographic equipment. As long as I'm bothering Henry about it, I may as well bother you, too.
Loving your most recent material!
So the mantle is like a lava lamp. Hmmm....
That does nothing to explain the more than 100 million cubic miles of consecutive layers of water deposited sediments over a mile deep around the world that buried samples of everything that was living on earth at the time. You people are fed a bunch of garbage and you eat it up.
Jungle Jargon Was this meant to explain that? The composition of the crust seems a little beside the point here.
Elliott Collins Yes, plate tectonics is used to try to explain away the evidence of the global flood and that argument fails miserably.
As a geologist, I approve of this very correct piece of information.
As an anthropologist who studies specifically geologists, i can confirm
As a physicist and a nuclear chemist I can confirm

yeah, only mistake I caught (which makes a nice change for video on internet about geology).

and this, my friends, is what I call “studying for a quiz”
the real question is, how long till the next pangea
***** Wow found that really interesting, thanks
Eemeli Bergström you wouldnt notice, this would happen over 250 million years not a day. the map printers would simply move how the map looks by like 1 cm every million years or something of the sort
Next Monday. I'll let you know when my earthquake doomsday device is ready.
I heard that super-continents are actually bad news for life. Seas and oceans act as climate moderators, so we experience moderate climate. Super continents on the other hand will bring in extreme weather (i.e. extremely cold winters and scorching hot summers). But this is stock knowledge, so I'm not so sure. :/
space would implode before that happens.

I'm going to fail that Geography test tomorrow.
How did your test go?
Rien B. Bad... Got one of the worst results in the class...
le tiggo lol
le tiggo I got a 96
Lmfao R.I.P
I really love how you explained all of this :)
and the drawing/animation is really creative xD!
(like how the plate tectonics are "moving itself")
I really hope your channels get alot of supports and subscribers!
okay, so we use satellites to work out the speed on the plates, how do we calculate the mantle's speed?
This is done via seismology.
v=s/t
so we get the speed of the mantle from slight vibrations in the crust? Or am I missing the nail here?
derLPMaxe - Generischer Name, Generischer Kanal. Much explanation, wow
kedwardsTWO v (speed) equals s (length) devided by t (time).
Your little knowledge snippets are great at making something one already kind of knows much clearer.
this changed my life, when i watched it on full volume i didnt hear my dad screaming in the other room if i wasnt watching this he could still be alive :_:
A whole month of my geography classes explained in 2 minutes, damn!
geographgdsioy is fake you mouth breather
@Maxwell Sherman no badd
We spent 2 weeks on this in school. This 2 minute video has made me learn more than those 2 weeks ever did.
I did not expect to learn something new here as I thought I had a pretty solid handle on how this all worked. I was (as is often the case with videos produced by Henry Reich) wrong. You should watch this, I'm sure you'll learn SOMETHING
You know what is the weirdest feeling? When you watch a video in school, then watch it at home. That is what I did with this.
oooh..... so thats why i didnt pass geography. youre a better teacher than my teacher.
Not me being here because the link on my school’s assignment doesn’t work so I had to search it up 👁👄👁
great video
How did no one see this
Oh u play pubg?
@@rnbwgamer9595 yes
Man, I searched about this in about 3~ 4 books, It was all getting over my head. I couldn't understand that if tectonic plates moves then how the hell continents can merge and devide, But a simple example of conveyer belt solved it all in second ❤️ thanks a lot
i learnt more by watching this video than what my teacher taught in 3 lessons XD
same
Botdfandbfmv Fan You must have a terrible English teacher as well with that spelling.
Yeah agreed Music dork
Thought I was gonna bomb a quiz before this thanks boo 💓💓
Edit: um I watched this 87 times 😂😂
I’m using this vid for a science report but I’m home schooled:)
I literally can't even begin to explain how much I love these videos
The thinner plate doesn't sink. it's the denser plate that sinks. The oceanic crust is denser than the continental crust and that is why we see trenches only underwater.
This is a really really well explained video, thank you so much!! the way you described the mechanics of how it all works is the best that I have ever heard.
10cm per year? Is it me, or is that really fucking fast?
Well, human hair grows at about 15cm/year, so it's kinda fast relative to some stuff, but still slow relative to other stuff.
But for the movement of the face of the earth.... fast!
This is just an average of all movement. But if it really moves, it moves really fast. In some worst cases many metres in a split second. This is what we call earthquake.
Compared to how fast Iceland gets wider (about 2 cm a year), it's fast.
it's faster than my internet. took me fifteen minutes to watch this video. thanks obama
That tectonic plate moving itself with their little arms made me laugh so hard idk why it was just too cute.
0:15 what is this drawing of south America dude. Sorry but I had to point it out
Really informative! Thank you for putting this simple but very educational video together.
Finally. It's about damn time my country became a whole continent.
What country?
Thanks @MinuteEarth, helped me out on some last minute geography revision
Anyone here for a school assignment?
Yeh all tho im 3 years late 🤣
Just did this in class today and makes much more sense now!!! Thank you !!
Tell me Im not the only one doing this for one of those stupid online lab thingsn in science class ._.
I really appreciate what you're doing. Please keep the videos coming.
Could I get my foot stuck in that crease if I tried?
You'd need a diving suit and some time to waste as it would take a while and you'd be miles/kilometers below the ocean.
no becuas ut not realy
If you were immortal yes because you would be miles beneath the ocean and the pressure would make you implode.
warms my heart when i see this video i watch it all day and it feels nice

Should be saying fluid, if anything.
I haven’t paid attention in science class for the past month (the teacher is boring and I’m sitting next to my best friend). I now know practically everything I missed from a two minute video.
What happened to stop motion marker animation? Cool video nonetheless.
That was one of the cutest little videos I've ever watched. I definitely understand plate tectonics now
I don’t understand a thing he said
real
facts
Yeah
He's trying to summarise everything and not explain so ya, this is useful for people who learnt the topic long ago
It means your dumb cant understand science
Can you please please do about tectonic boundaries, an example of where they can be found in the world and what land formations and events can be found there? Love your videos ^_^
1:10 laughed my ass off
We were learning plate tectonics in class and I remembered this and sent it to her. She said that she loved the explanation
can you be my new teacher please, i dont want the one i have. please give me a refund fast
Was looking for a video about tectonics. Didnt find anyone especially good... except for this one! Very pedagogic, awesome. I only wish it was longer. :) Cheers!
Thx
My teacher would have taken 3 weeks just to explain that
And I’m in a honors class
bro i learned nothing from this i just drifted off in space while the video played and i do not want to watch it again lol.
Wow! This video did a amazing job 2xplaining tectonic plates! Thanks minute earth!!!!!
The earth grew in the past, plate tectonics is the same as flat earth theory, incorrect.
Yes, once the dinosaurs died out and stopped pooping into volcano craters, there wasn't enough matter being deposited to sustain the earth-swelling process. But TH-cam comments may be a promising new source of shit.
Fun Fact: The oil that we drill out of the ground is actually what causes the tectonic plates to move smoothly otherwise there would be too much friction and the plates would not move.
I guarantee you there are no oil slicks between plates.
Fun fact: The moon does indeed have the texture of cheese.
Meh, the USA is not a continent. It was a good video though - as it is anytime on this channel.
Had to look pretty closely to find where this was implied. Nicely spotted :D
Yes!
***** One thing is sure. Continents are about large land masses. And the US is a country, a political formation not a topographical.
***** Australia is a country which owns most of the area of the main land mass (continent) Australia. It sounds weird, but it's like that!
Neither is a lava lamp, why aren't you complaining about that?
I can’t belive that you have translated this videos in arabic, we need that , thank you so much
Who’s here for science homework 📚!! 🙄📚😆😫😭
The opposite Sisters me 😪
I understood this better than my teacher’s lecture, thank you so much!
All BS. God moves the continents, and by the way, the earth is flat.
No.
Aliens did it
Look their minute physic and vsauce's video
No, the surface of the Earth is actually on the inside of a sphere. You can use a telescope to spy on the other side of the world from above.
But is it a flat square or a flat circle?
You're partly right
The earth is a cube, so while it may seem flat at any given part, there are 5 other "flat" parts as well. God lives inside of it, hell is in space.
I literally just learned about this in school and already took extensive notes on it and only missed one question on a 30 or so question test, but I want to write really fancy aesthetic notes on the topic because I'm bored, so I'm watching this to do it because I don't have my binder with all of my papers and stuff in it
i dont like it becuz he talk to fast :(
there's a speed changer
You're right. I slowed down the speed and had talk almost like a drunk.
I spent too much of my life understanding the process, but unable to visualize.
Thank you! This knowledge feels much more grounded in reality now. (No pun intended)
idk if the music has been the same in some other videos but i really enjoyed the music in this one! :)
The continents are baggage. Classic! Love it. And great job of explaining slab pull. It’s something I wish was taught much earlier in school science.
Thank you for teaching me something in 2 minutes I've been learning about for a month and will still continue to learn about it ._.
You explain it so simply, thanks.
Just showed my students this! (year 6) They've learnt a lot!!
My teacher showed us this channel now I am addicted.
two points: 1. oceanic crust (basaltic) goes under the continental crust (granitic) because it's denser, not because it's thinner. 2. Google Earth is either upside down according to its rotational direction OR it's spinning in the wrong direction if the orientation of its axis was intentionally placed with the South Pole in the "up" position.
my geography test is tmr and this really helped me :)
super job. A bit fast, but really liked it. I will show this to my 7th grade science students. :) My favorite part was the crust breaking off.. and the suction.. and the continents ARE baggage. Do more!
In a nutshell in plain English! Great video! It clarifies it and gets right to the point.
Pov:
It's two minutes before the test and you know NOTHING.
Thank you so much i have a school project and this really helped on it.
This video got me an A+ on my science test
THANKS FOR THE GRADE
Great video!!!!! I am in school and learning science, I am definitely going to start watching these. Very cute and helpful!!!!! 💖🥰 Grabs my attention very well.
So short but so helpful! This is great for the test I have soon!
Look forward to this every time, beautiful, informative and entertaining, please keep it up.
This should be enough studying for my test tomorrow. Wish me luck!
I LOVE IT WHEN I LEARN MORE FROM THESE VIDEOS THAN I LEARNT AT SCHOOL THAT DAY XD
Great video!!! Helped me on my geology exam!
Plain and simple. Love it.
That's so cool!
There's a lot of interesting information here to build what we already know (or think we know) about tectonic plates!
this is my work for school
Thank you for teaching me this because we had a big test in the morning and I got a good grade thank you
Correction 1:20
it is not the thinner of the two plates, it is the denser of the two.
Continental rocks are made up of felsic and intermediate rocks (High Silicate%, low Fe+Mg content), which are less dense than the Ultramafic mantle (very high Fe+Mg content). That's why continents are ontop of the mantle.
Oceanic plates are made up of mafic material (high Fe+Mg content, less than the mantle, more than continental crust). So when an Oceanic plate and a Continetal plate collide, the Oceanic plate subducts (goes under) the continent, because it is more dense.

The general idea is correct, but it isn't for the exact reasons you stated.
(I'm studying geology at University, we do not know all the answers and hypotheses are always being improved, but the above is the recent info on it)
Not reading all that
What happens to the pieces that break off? Does it mean that the earth is constantly becoming smaller? Or is there some way the plates "grow" and thus keeping everything balanced? Thanks in advance

This video is from 2015 and Im here from 2020 watching this for class
1:12 to 1:14 is such a beautiful animation =D
thank you, i understand what plate tectonics are now thanks to you
The Lower 48 U.S. States are not considered by most a continent. However some definitions do agree that Australia is a continent of which I disagree. But overall a great video!
Great video. Also, loved the end music. It was kinda relaxing. Very nice. :)
This was pretty cracked, Tectonics are top tier. would smash
What happens if a plate completely sinks and breaks off under another plate into the mantle? Is there just a big gaping hole where you can see mantle? Or are there new plates that form?
That's what I'm wondering too.
This sinking process is extreamly slow and as it happens new rock forms.
I think the subducting plate is going under at an angle less than 90 degrees so you wouldn't see what is underneath entirely, jus deep trenches (still part of the earth's crust). And yeah, once a plate had completely subducted, new material would've been created on the other side. :)

Slower subduction produces a shallower angle. Compression (causing slower relative subjection rates) in the backarc produces a shallower angle than extension (causing faster relative subduction rates).
1) Mantle convection
2) Slab pull
3) Slab suction
4) Ridge push
These are the 4 forces to drive plate tectonics.

Does the oceanic plate subduct because it is thinner than the continental plate, or is it more to do with density? The video seemed to suggest the former rather than the later.
