"our potato, I mean earth"
Nice save. Cant let them know about the real earth
Wait it's all potato
*chuckles*
always has been
bang
I 555 percent of the time and I don’t know if
1:34
NOT POTATO
Yeah phew
So, his REAL mistake was not using a liquid potato.
+Diamondmyna Indeed.
ROLF!
Diamondmyna T-T I don't even know what to make of it.
rolf? you mean rofl
Diamondmyna a mush potato*
Instructions unclear, got an F on my Earth/Space Science class because I told them Earth was a potato.
i thought all ur comments had 2 thousand likes
bruh did u watch every video on youtube
Watch the full video again, they stated at the end that the earth ISN'T a potato
@@localdruglord550 Only dumb people don't get the joke.
@@TBTornado can't tell kpoop stans nothing lmao
Me: *looks at title* haha I know I LIVE THERE
So hey random arazonian
😂 NOOOOO LOL
I live in a cave
You mean Australia?
Same
So basically, the lesson is that the earth isn't a potato?
But I'm pretty sure your brain is
But potatoes are good for your health.
What the fuck was that?
Julian Gunther Wow, what an insightful and inspiring response to this comment. I have been move to tears with how deep and meaningful that comment was. My life has been changed forever.
It's a radioactive potato.
As an Irish man I like when things are explained in terms of potatoes.
TITANSPIRIT
Irish people and farmers seems to like growing potatoes 🥔 for some reason
Haha!do you like potatoes?
I think you should visit Belarus.
Potatoes are the fruit of the soil, you can bake them fry them, mash them, roast them, boil them and on and on! You can even ferment them, and get Vodka. Kidding aside, It's a high energy food source. Some boiled potatoes, with cabbage some spam and a bottle of vodka, kept a field army going till victory!
Where would we be without the Columbian Exchange?
It depends on how deep, if only 10-20 feet underground, it is pretty cool like wine cellar. In fact, there are underground food storages that are shallow deep, to keep food cool in summary, and not frozen in winter.
to put it simply
CORE HOT! BARLEY SPACE UNDERGROUND! FFFFIIIIRRRREEEE!!!!
Wut?
U wot m8?
😄😄😄😄
How the *darn* do you guys not understand?
😆😆😆😆
This is a perfect example of how science works, Kelvin made an estimate on the data that he had. Later scientists found more information that proved the original estimates wrong so they changed based on new information. I love stuff like this that shows the self correcting nature of science, why can't my religious friends see how great this is!?
The thing is, Lord Kelvin died believing he was right about dating the Earth as 20ma years old, back then 20 million years was a leap from 10,000 years which was popular belief. It was moving in the right direction but no way near the actual age of 4.55 billion. It took observations by Geologists, famously, James Hutton to begin to answer the question of the true age of the Earth. Although Hutton died without anyone believing him.
Right, that still shows the correcting nature of science though, which is awesome.
Craig T lol you are one those people that treats science like a religion , you treat science like an all powerful unquestionable god that can do no wrong
It is!
lol no I'm kidding, but I do have much admiration for science.
Craig T I agree that science is a self-correcting process. However, the ego of human scientists often holds back that process, and we have to wait for them to die to make progress
So kids, what did we learn?
Earth ≠ Potato
+Isaac McAuley nothing. I understand nothing
+Isaac McAuley
Earth is more like a radioactive potato with metal nails stuck in it.
Exactly what I was thinking...
that theirs a new number system thats called 400 thousand million? lmmfao

*_Dangit!_*
because I buried my lit mixtapes broski

Food chain?
You guys are doing a great job! Well done!
Did I just see Goku riding a turtle through the Earth's mantle?
Expected this comment haha :) Thanks
The Curious Engineer
oh! You're Omkar Bhagat!
I really appreciate that you took your time to work on this. Thanks ^^, your animation was pretty didactic.
Thanks for everyone involved in the making of the video.
The Curious Engineer Very nice videos you've got there!
Subbing
It all makes sense now. The heat from the Earth is the result of an epic, turtle-mounted Kamehameha attack! Good ol' science :)

Why do you feel the need to sign off on all of your comments?
Glad you covered this hot topic.
I bet you think you're *cool*.

Probably quite a moldy potato
But she said it's not a potato God damn it
I like the video but I gotta say, I liked Henry a lot more. His voice is just... so soothing and good for these videos.
Hmmm...
***** HMMMMMM
I like 'em both. I wouldn't mind the voices alternating every now and then.
Alex Egan No your opinion is wrong.
Daniel Galindo Yeah, well, that's just, like, your opinion, man.
Awesome! It keeps you warm from winter
Six years later and this video still educates pretty clearly
She has a great voice, could we hear more of her
She sounds a lot like Vanessa Hill of Braincraft
Nickesh Chauhan Say who?
***** It's a similar channel specialising in psychology and biology, rather than physics & maths. It uses a stop-motion paper cut-out style and is pretty cool.
Nickesh Chauhan Oh, okay. I thought because of the name it was another minecraft channel... thankfully it isn't!
***** Yeah, I can understand that. There aren't many channels which manage to do Minecraft in an interesting way (though I like the game, among others of course).
At least Kelvin gave it a good shot... and he certainly got a better guess then a certain book.
Oh! Is that book harry potter? No, no! Lord of the rings! Wait! The Hobit!
The cat in the hat?
That's what you get when you actually use scientific metod insead of a leyend book.

@@Confused_Rock Did the Bible say the age of the earth?
good job M.L.E verry nice narated, you should do this more often.
Very helpful. Thanks for your time.
LOL that turtle riding radiation guy =D
Thanks ;)
The Curious Engineer You did draw that/all these? Well done. I really like those little jokes you make. =D
I didn't see any turtles riding a radiation guy. You must be confused. Oh, I see, you're just ignorant of hyphens, nevermind.
wtf, the earth is not a potato, this is not my Norwegian point of view, everything is fish and potatoes.
OLAV THE VIKING what the heck are you taking about ??
if the earth is the potato then where is the fish ?
Mega Hunter beneath the peel
The Earth is secretly made of tanks.
wtf, the earth is not a potato! In Vietnamese view everything is tradition and food! (And potatoes for me since I am one and earth is not a Potato.)
Great illustrations, very **compelling.**
This is the first MinuteEarth video i watched!
2:25 from what I can see here earth isn't a testicle
That is bigger and deeper than the ocean lol
Do you only have one testicle?
?
Wow
@@Heligoland360 you have more than one??, you weird
Really well done, and i did learn something! (As usual) The voice of Emily may not be as "Radioperfect" as yours, Henry, but still very enjoyable! After all, a big thank you, to the team as a whole, for making these videos!
Thanks. :)
Emilys voice scared me at first XD I wasn't expecting a female voice.
Density and the layers
I LEARNT ALOT FROM THIS VIDEO
THX
that four and half thousand... million years was such a troll to creationists
So earth is a huge donut with hot jam in the middle. Got it.
Thank you Emily for narrating this video!!! Much appreciated from deep within the core.
Because I buried my mix tape down there, duh.
bonecanoe86 lol
It's lit
Copied the comment literally above you
Theif
Need more Emily narrations
Then how did they make the journey to the centre of the earth in that totally non-fictitious book?
They rode a turtle
Yeah! Didn't you see, the radioactivity guy in the center? He lent them his turtle. They just never bother mentioning it in the books! :D
This actually is explained in the said book (journey to the centre of the earth). In their time idea about why the earth is hot was still quite splitted. If verne was right about all that stuff (heat, volcanos...) it would actually be possible.
But I get your comment, it's funny :)
Also the book is so much better then the movie.
*****
Me? Yes (Journey to the center of the earth by Jules Verne)
Dont know for others or if you were talking about them beacuse of youtube being broken at moments.
Thanks for the video, I learned something :)
great info and ...yes thank you for using Emily Elerts' pleasant voice..
At least Lord Kelvin didn't think the Earth was just ~4,000 years old!
+Cryogenian Well, some people still think that earth is 2016 year old :)
+PatrykZ94 Right? I mean duh! It's already 2016 years old!
we don't know the age of the earth scientifically because it was born from the electromagnetic pinch effect. which is matter concentration or extreme compression of matter. The earth formed in one of the stellar birkeland currents coming from the sun. Excluding religious beliefs, the earth could be anywhere from 6000 years old to 80 billion years old. We just can't know. All we have is written history to tell us it's at LEAST 6000 years old. I'm certain there are a few planets out there that are just 1000 years old.
+Chandler Greskamp So you ignore the radio metric dating of rock which show that the earth is at least a billion of years old? How about other geological phenomena which can only occur over hundreds of millions of years?
Bananaman I'm not ignoring it. But at the same time I don't accept it as a reliable way of dating the earth or individual rocks. Can you show me where radiometric dating has actually dated something if previously known age? Every time it happens it's way off. So I pump the brakes every time I here "radio metric dating tells us the age of this rock" or whatever. I am a supporter of the EU (Electric Universe) Theory. This means that I actually scrutinize every "fact" that is put in front of me to see if it has its foundation in truth.
cool (it's a pun)
If the earth was a girl, she'd be hot (another pun)
Wow, im watching this in 2020 and i right away I noticed the audio quality. Wow. You have improved alot audio wise the ark stile hasn’t changed that much at all
Yep. It's so old that Emily got a shoutout for being a guest narrator, and not an official member of the team 😆
@@EthanParmetItsDaBunny W O W
Your videos are so great.
I don't know if you have changed anything or if the subject matter is just not as complicated as usually but somehow this video was more accessible for me :)
Great episode, thank you so much for doing these.
absolutely loved her voice!!
+freak-teek
Too much vocal fry.
+Dirty Robot dangit its all i hear now
freak-teek way too much vocal fry.
freak-teek, me too
freak-teek
Than go married her.and where's the wedding going to be at
how do you know?
this honestly sparked more questions than answers provided. and as soon as we got to calculations you've only provided answers for what you said was wrong, then said "it's... not."
What I got from this is that earth is a giant baked potato, now if you'll excuse me, I'm gonna pour tons of cheese and sour cream in my front yard and start chowing down on the baked potato!!! XD 😸
Instructions were not clear. I threw my potato inside a mine and now it's gone
If you think about it long enough, it's actually rather crazy that some distance below each and every human alive today is a giant ball of hot swirling molten rock
Foodstamp Amp'd I know ey
Or you can realize that it's all a lie and you're being deceived
i allways love they vids
Just got here. Love Emily!
Well, 4.5 billion IS extremely fresh from the cosmic oven.
+Boltzmann no, not really, as the cosmos is just about three times that old.
Imagine you're thirty, and you are eating a ten year old bun. Is it 'fresh from the oven'? Not really. If someone lived 1000 years, it might feel like its quite a young bun, but no. It's not.
+Richard S. Would a 30 year old not consider a ten year old in fifth grade young?
+Boltzmann and 4.5 out of 13 is fairly wide of a gap, regardless of analogy.
+Boltzmann nah extremely fresh is definitely the wrong word
+TheRABIDdude I suppose the *extreme* can go; but it's definitely young. I just used the videos wording to maintain continuity.
Question: If heat takes such a long time to get from the core to the "surface" (or in this example to the mineshaft), then how OLD is the heat one feels down inside a mine? is it heat left over from the creation of the planet or is it recently generated heat like the heat generated by friction of the mantle?
Is the core/mantle constantly CREATING heat or fueling the heat in some way therefore keeping the earth warm or is it ALL heat from the time when earth was a blob of molten goo??
George Smith well the core is constantly making heat from nuclear fission
sarah madouni err no. There's no nuclear reaction going on inside the planet.
It's molten rock and metals.
Nuclear fission is what powers the sun I think you'll find!
George Smith blogs.scientificamerican.com/observations/nuclear-fission-confirmed-as-source-of-more-than-half-of-earths-heat/
George Smith Nuclear fission is what is utilized in nuclear reactors by splitting atoms. Nuclear fusion on the other hand is smashing two atoms together and is used by the stars.
mckay skipper
yes, certainly not what's going on under our feet!
@MinuteEarth could you please make a video on partial melting and fractional crystallization and how this affects the chemistry/density of the continental vs the oceanic crust? It would be awesome if more people knew about this principle
1:17 or 4.5 billion years old
k
4.5 × 10⁹
So now every Person in every language knows what was said.
The british use billion differently, they are being thoughtful
@@blacktimhoward4322 oh i see
that probably where the story of hell came from
you're
Naeisha Marie Inguito T.F.W when you get corrected when you are correcting somebody. 👺
it more than likely played a role in some way.
It's not a story.
So it's a reality? Please provide us the evidence then.
you have not given the answer??
+Pankaj Singh You're right. She mentioned radioactive decay, but that is not whe only reason. Here it is: The solar system started out as a (relatively cool) giant gas cloud. Over time gravity compressed this cloud into the Sun and planets. When things compress, they heat. That's it, really. A giant cloud of, say, 100K, may become, say, 1000K when compressed into a planet.
No, she definitely did give an answer starting at 2:04 convection currents in mantel material spreads heat more evenly through the planet, specifically carrying heat from the core to the crust, which heats mine shafts (as well as other effects).
+phiefer3 read the question again, "Why is it Hot Underground?"
I think you read the question as,"How heat spread...?"
there is a difference between these two!!
They never give a clear answer
*facepalm*
DUDE I NEED THIS SINCE WERE TALKING EARTH TO SCIENCE CLASS
Thanks kermit, very cool
because hell
Cgit Einsteins what is hell?
A place where people who don't worship god go
And all the call of duty noobs
SiR3 River thats sound radical xD god is a dick
And people who buy Jakobs munitions
Most religious arguments: you havent seen the core of the earth so you cant impossible say its a fact bla bla bla.
oh my god the irony.
lol i know this comment is 2 years old but the fact that you said oh my god is also irony :D
Albin Grahn Imagins if that guy is dead like 2 years passed and he died
Leonardo Oliveira oh my god i didnt think of that D:
Albin Grahn Ikr kinda depressing XD
Had to watch this for my science class
I would think another oversight he made was that Hot Potatoes use conductivity (and yes can also use convection currents) to transmit their heat.
While the earth being situated in the near vacuum of the solar system can pretty much only use radiation to send out its heat.
Great video, and I really liked her voice!
And all this time I thought it was because Hell was down there.
That's what I believe scientists just r too afraid to admit god is real there has to be Cold hard facts for it to be true *rolls eyes*
***** how can the scientist be afraid. There's no facts. I hope you're kidding
***** I'm afraid of the boogieman. You should be too. Just because you don't believe in it doesn't mean it's not real!
***** Skydyed even did a "rolls eyes" at the end, yet you still didn't understand sarcasm was being used.
***** You're completely mistaken again. You see, I wasn't really defending skydyed; I was actually just calling you an idiot.
It turns out you're even less bright than I thought. Good job.
Every time I have been in a mine it has been much colder than on the surface, guess they weren't deep enough.
When I saw this video, I instantly came here to say "The earth has a hot core".
This is teached in 2nd grade tbh
More Emily, please :D
yes!
No stop jerking!!!
We now know? Wow when are they going to admit they have no clue of the earths age. Every dating method has been proven inaccurate.
They might not know exactly how old it is but it for sure isn't 10,000 years old
For sure? You don't have hard evidence of any dates pre history. It's all speculation.
Thanks for your input. Now go back to Jesus videos, imbecile.
Modern dating techniques are accurate. There is of course some inherent error, like with every experimental result but even with taking the error into account, the earth is very nearly 4.5 billions years old. We know 100% that it's not 5000 years old or whatever nonsense you're hoping to hear...
arthurthegreat Its true, how do we know for sure? fr all we know we could be using the wrong Calculations. would not be the first time, secondly, there is far tomany thing wrong the with the bang theory, and cant be proven hence "theory".
That's a weird way to view things. So because some people got the age of the Earth wrong hundreds of years ago, the modern techniques has to be inaccurate as well?
Haven’t watched but my answer is LAVA!
When they mentioned the cooling baked potato I got unpleasant flashbacks from the AP Calculus AB test this year.
Best drawings ever!!
who says thousand million?
Billion
milliard!!!11oneone
Yah really. They should just say 200 million 5s. :D
This is to clear any confusion between the american billion (1.000.000.000) and the scientific billion (1.000.000.000.000)
Validifyed There someone goes again, claiming it's all America's fault. There's a long scale and a short scale, and guess what? Half the world uses the short scale along with the US.
Congrats on calling *half* the planet a fuck up.
TheStoneSpiral Why would be calling that half of the planet more inappropriate than calling quarter of the planet?
Imagine digging close to the core of the earth and harnessing that heat to generate electrical energy !
In the mine I worked 5 miles down it was 55 degrees year round
I thought we answered this already: Aliens
I was not expecting the comments to be so toxic on this video. That is disappointing.
do you even internet? it's like this everywhere sadly.
so. basically the core generates heat onto the planet's surface and few out onto space and causes it to the nearest location get hot, like 1539 faranheit or something in the core, since it gets the most heat since it's the nearest. the rocky surface inside gets more heat due to this.
sorry if my thinking is incorrect (i did it before i watched it)
Cool!
@MinuteEarth I think You've made an error in describing how radioactive heat drives internal temperature. Heat released from radioactive decay of K is one of the biggest contributors to internal temperature rise. That element naturally partitions into continental crust at a much higher rate than other elements because it's less dense and dissolves into melt quicker than other similar elements. K exists ubiquitously throughout continental crust and as a result its radioactive decay causes internal temperatures to go up. Because rock is an excellent insulator that heat gets trapped. Also, conductive heat from the inner core is arguably the smallest driver of plate tectonics and doesn't work like a conveyor belt. Bad analogy. But nice try.
I think you have a point about the radioactivity in the crust and the crust beeing an insulator - i think i learned that sometime in my undergrad geology study but for some reason it is usually left out in these explainations. The reason you are giving is however not quite correct. Its not only radioactive isotopes of K but also Th and U that are concentrated in the earths crust due to fractional crystallization - however this has nothing to do with density (it makes no sence to talk about density when talking about ions anyways, and you wont find K in the metallic state in the crust its extremely reactive) but with compatibility which depends on the valence and the ionic radius of a certain element - K, Th, and U are incompatible i.e. they go in to the melt
so what we learn here is, ppl compete for most likes.
Hi, I am from 3 years in the future and let me tell you it is getting a lot worse. Really annoys the crap out of me when you see a variation of the same comment on EVERY VIDEO.
Thoughty2 made a video about it. Likes release dopamine's into the system making the person that receives a lot of likes feel good and they become addicted to this, and hence why most people say shit just to see how many likes they can get. Pretty sad.
I love it when people surfing youtube became comedians in comment section. Thanks for entertaining people without being paid
Short answer: because you are getting nearer to the core and the core is extremely hot...
I agree strongly
Did you not watch the video? The core gets nearer to YOU!
well, similar comment i made
What's core btw and why it's hot?
Yea
I would honestly be perfectly fine with Emily being the permanent voice of MinuteEarth. Nothing against the current narrator, I love both this channel and MinutePhysics, but I'd like to see, er, HEAR, more female voices in scientific education. Also, she's pretty damn good at it.
So the main takeaway of the video is.. the Earth isn't a potato. Man I love learning.
*Sticks finger in a hot potato*
Baron Kelvin: I DISCOVERED HOW THE EARTH WAS BORN
3:45
LOL EPIC
Age of our potato. Haha
Yes. I am relieved to know that I do not live on a potato.
It would have been amazing to see the creation of our planet 4.5 billions of years ago, what a show that must have been. If time machines can ever be invented, that is one time I want to go back to.
It might also have to do with the voltage of the earth's EM currents.
Instead of saying magma dynamo creates earth's EM fields, maybe it's the other way around?
I like Emily's voice they should put her in more videos.
Today, I learned that "Earth =/= Potato."
Underground you say
Me: it's hell
🤣😂😁🤭😵💀👻
every cave I've been in is always like 20 degrees cooler than outside
