i like the way the earth rotates, really makes my day.
Vince Andaya lol I get it
I like the way this guy thinks.
i love this comment ahahahaha
Nice joke Frog bot
Hmm
in 10 minutes you explained what schools tried to teach me for 12 years !
sara meachel Yay!
Not sure that's something you want people to know.
sara meachel And It's much more effective surprisingly.
sara meachel It's because school isn't there for you to learn. It's there to teach you how to be a good blindly obedient robot.
Sit down, shut up, raise your hand to pee, sit down shut up, stand in line, sit down shut up.
It's based on the Prussian model of public education wherein good soldiers and good tax slave working robots are to be manufactured.
The government cracks down and regulates home schooling and private schooling because they don't wish for there to be places of education where you can be entirely free of propaganda.
They, in effect, have a monopoly, and it is very, very, very effective.
WTF are you talking about? The educational system is bad here because of so many kids. They have to spit out as much info as they can without confusing them by going so fast. That's why private schools are good, because they're schedule is based on the child's ability to learn.
Can't get over how amazing that intro looks.
SBroproductions Isn't it incredible? It still blows me away, too! The whole team at Thought Café is just the best.
-Nicole
CrashCourse
The jingle for the intro of the astronomy episodes is my favorite, although it could just be the Neil Armstrong quote lol.
Logan Podojil Definitely the best. Wish it could be my ringtone.
CrashCourse (*Heavy breathing*) I've been acknowledged by a Crash Course Member (*Heaving breathing*).
But seriously though it's a really well made intro. The ONLY thing I would like to change is the timing of the scene shifts so that they match the jingle of the theme. Other than the logo to the "telescope" scene, all the other shifts don't match the "DANANANA" of the song.
Logan Podojil The quote certainly sells it! I also love that it's a very on-theme spin on the song. I was/am equally blown away by *****'s work :)
-Nicole
Lol, I loved the "Bacon" Image right as you said the Earth has something very important.
d4rk0v3 BACON! Very important.
-Nicole
d4rk0v3 If clouds are so great, why don't they rain bacon?
oscargordon That would make jewish people look foolish. ::Imagines a hasidic jew walking through a downpour of bacon:: That's just foolish.
Bob Hope Some must suffer so that others may bathe in glory.
Bacon is muuuch more important than water, I mean that's just science fact...right?
"Earth is the only habital place in the solar system. And you know what? We should keep it that way." Anti teraform-ist confirmed.
Ambiguous syntax ftw
Derek Swan well until FTL travel is invented and humans inevitably screw up the rest of wherever we go, before that it'd be like breaking planks from the only raft to build a fire
Da ve We'll destroy the Milkyway galaxy to look for more oil and then make a day called "Intergalactic alien apology day" to apologize for the trouble we caused.
Derek Swan That's why it saddens me that I live in a country where the Prime Minister is a Climate Change skeptic.
+Paul Howard At least you don't have a whole political party doing that!!!!!!!
"Earth has something VERY important"
*bacon pops up*
After science, at least we know whats important to him...lol
"I've never seen an aurora...someday" Same here.
oof
its kinda crazy a person of his caliber hasn't gotten around to do that yet lol. whats that say for us peasants that wanna see em?!
I live in Canada, they are beautiful, but annoying when you are trying to sleep.
The 1968 photo, Earthrise, taken from lunar orbit, really makes you appreciate the planet that we inhabit. We need to do everything we can to maintain that beautiful view.
I hope there's crash course Earth Science too.
Would be cool
I love astronomy
Same
Same here
Yah. Astronomy and physics are my best science fields.
Me too
Mom: *have you learned anything?*
Me: *yes*
Mom: *what is it then?*
Still me: *$cienCe*
$₵ien₵e
I love this channel! And I like learning about earth.
I'd also recommend the KurzGesagt video about the Earth, it's really great too.
Wow. Kurzgesagt is a great channel. Thank you for introducing me to it.
Woah Kurzgesagt is the best channel in the history of youtube
Thanks.
This channel is life changing. I want to thank you so much for introducing me to it!
I use it for fun learning
"Breathing has its advantages."
I died. 1:13
And lost your advantage.
An aurora are so beautiful. I saw them several times when I lived in the north part of Sweden.
I just love how our planet glows in the suns light!
This is my favorite series! Can't find anything like it on CZcams
u helped me with my science fair project
"1% of argon, of all things..."
"1% Argon, of all things" Dunno why, but that made me chuckle :'D
I absolutely love these videos Mr. Plait! Long time BA fan
The opposite of terraforming should be terrawrecking.. The earth is getting terrawrecked.
+krillinmesoftly Tell goku hi for me.
krillinmesoftly except it has survived far worse than anything we have thrown at it... look up ice ball earth or the great dying... we are a biological blip. Don't attribute God like abilities to a race as stupid as human beings
krillinmesoftly, We're not harming Earth that much. We may be a bit too harsh on Earth's environment but it's not that bad
Can you imagine the progress we would have made if George Bush, instead of talking about Terrorism, talked about Terrawrecking?
I motion to, from this point on, refer to climate change as "terrawrecking" Oh, or maybe Terrorwrecking?
Venusforming
I was just revising this today and yesterday for my exam in the summer! Perfect timing, thanks!
4:42 all that destruction...it's so lovely ;-;
Earth is a Planet 0:03
Layers of Earth 1:25

Atmosphere and the Human Influence 6:14
i was really skeptical about a non-green crash course but im really enjoying these. keep it up, phil :D
The Sun is a star and now Earth is a planet! I'm not sure what to think anymore
the sun is not a star,and earth is not a planet, earth is flat.
Just in case this wasn't ironic. Have you ever done analogies? A is to B as C is to D. (denoted A:B :: C:D) They should have been on every standardized assessment you took. So Here's the simplest way of understanding it
The Sun : A Star :: Broadway :: A Street
Earth :: A Planet :: Mona Lisa :: A Painting
So, yes, the Earth is a Planet and the Sun is a Star. One is the name of a specific one (though sometime a sun is algo genericized to reference a star with planets, but lets not overthink it). The Sun and Earth are ours. Earth or Eorthe (Old English), Jorth (Old Norse), Ertha (Old High German) used to just mean Land. The Sun was Sunne/Sunno/Sunna (same order I posted for Earth). They are just names. Not Ah-ha moments.
This series blows my mind several times an episode so much i'm sure i don't actually understand it. This one nearly answered a question 8yr old me had. If air does have weight, why can't you feel a perceptible difference when you walk outside?
Also. Thank you to everyone that helped make this, & Crash Course in general. Learning is always beautiful, incredible and sometimes fun. Y'all have amplified that last property making my life more of the first two. I doff my hat to you, bravo
Earth has something really important: Bacon
So true. If bacon's taken away from us then the world shall end.
I love this channel. So much cranial goodness
Did anyone else shudder at seeing the temperature go up from the late 1800s to modern day?
No, because i have air conditioning.
No because data is manipulated to scare people like you who fall for that dribble
@@janello3 You must be one of the dumbasses who denies climate change
@@ianhubbard641 climate change is real but humans aren't affecting it like we are told.
@@MrBassbump So it's all just a coincidence that the earth has been hearing up at record rates since the industrial revolution and humans aren't at all to blame?
Thanks for making this series! It's great!
Even though I may know some of the facts or some of the videos are ones not specific to my interests I still love every video you guys post. Can't wait to watch the next one!
Lol 3:00:
Phil:" It's made up of many different plates"
Me:"Lol It's made up of many different PLAITs!!"
DADUM CHHHHH
-_- get off the stage
the best series in crash course history.....!!
This channel is my go to revision channel and the way you explain everything makes it all make sense! Chemistry videos would be awesome to see and watch. Thanks for all the videos on behalf of most teenagers studying right now!
They already have a whole course on chemistry, just go to their channel and look under playlists.
What a great show. And what a great host. Phil is awesome and i really like listening to him.
I love that there is another a geology centric crash course! I am only slightly disappointed that there has no geology crash course, but it comes up in other places like here and Big History. But I will still lobby for a geology/geoscience crash course! (you could even fit climate in that crash course).
There should just be a crash course for everything haha Give them time and eventually there will be, I hope.
excelente curso, muy entendible
Great show! Thank you guys, you're the best!
This is such a helpful video! I love this channel.
Utilizo este canal para aprender ingles con mi materia favorita "astronomía".
Crash course philosophy
but it will be amazing. philosophy is love, philosophy is life
***** Better get started then ;)
Diana Peña Isn't that exactly what LIFE is though
#mindblown
Diana Peña The Greek philosophers didn't build Athens physically but they built its soul. The Acropolis may disappear one day but the thoughts of Aristotle lingers on ad infinitum.
What is useful? Building stuff? Bankers playing with immaterial investment bonds? The Germanic tribes were more physically "useful" when they focused on the military than "airhead talk", but they sank western civilisation backwards by at least a millennium.
Is your toaster "useful" because it makes toasts, therefore tangibly more important to life compared to philosophy? The material is "useful" in its lifespan, after which it's gone and prune to history repeating itself. The immaterial is useless in the short term, but invaluable to the building of other immaterial things like, oh I don't know, CIVILISATION?
Da ve YOU SIR! Have blown my mind.But seeing how you talk about how useful or useless is useful makes me guess you did have some sort of philosophy class.So i like to ask,do you know where to start learning the basics of philosophy?
I've, sadly, never seen the aurora either. However, when I was in AK back in '84, I saw the midnight sun while spending the night, during a 2-day arctic tour, in Kotzebue.
Love this series!!! Thank u!
y'all we need crash course geology
Thank you very much for making this video, Phil Plait and the rest of _Crash Course_ Astronomy! It was really interesting to learn about our amazing home planet, I just hope my future children and grandchildren will see the planets beauty before we humans destroy it all.
Although I am very content with your videos, I was a little bit disappointed that you did not mention the Latin and Greek names of the planet: Tellus and Γαῖα.
the video is mostly like a recap of what you would learn in a course. so I think that's why he didn't mention Latin/greek names since people usually don't think its necessary to teach.
+Here For The People not course but lecture.
Another great episode. :) I've read in a couple books, including "Rough-Hewn Land," by Keith Heyer Meldahl, that the motion of Earth's tectonic plates is due to the pull of the edges of those plates as they're subducted under adjacent plates and sink into the mantle, rather than to mantle convection.
excellent video and amazing graphics. big thumbs up!
The "earth" without 'art' is just 'eh'
*Badum tss*
Planet - art = planet
Planet-art=Planet-art, you can't take away terms out of nowhere. Unless you're saying art=0 which would be a burn.
RiverRainWarrior Fart - art = F
Thomas Stewart Fuck me, your right...
Proto-earth? You can't fool me, I know Mustafar when I see it.
+LordBaNZa Yikes
Yeah, look at all that high ground
great video Sir ! Thank you for making this ..
Most righteous information packed 10 minutes Phil! Just the right information for my biology course too! Thanks!
So, here's the Earth.
It's chilling. Dang, that is a sweet Earth, you might say.
Whoa, whoa who the hell's this guy?
He's PHIL FUCKING PLAIT!
Haha
I get the reference, but we need to go deeper.
The way I look to the world changed in 10 minutes!
First time to watch anything on this channel and I'm fan already :)
I love this series!!!
You"rock", with your course about Earth, Phil.
can we just appreciate the intro remix-
I just gotta say these thumbnails and also the thumbnails in the Anatomy course are the best i have ever seen just beatiful
Thanx, Phil.... very cool, and helpful.
Wait, are we studying astronomy or geology or chemistry?
Liquid water on Mars!! So exciting!!
Yeah
OMG you suck
+Hangshuo Zhang no, he's just exited about the idea that liquid water may mean that extraterrestrial (simple,but still extraterrestrial) life, which may also disprove a couple of religions but that just an added bonus/detriment (some religions are SO nice to meet up with and get to know).
+General Kobi whoops left out a section there, hang
* exists on mars
+Kira Burns The water on Mars is kind of liquid. It's not liquid water like we have on earth. Water on earth flows freely, the water on Mars flows through different salts. Mars is much too cold and the atmosphere much too thin to have free-flowing water.
To get an idea of what this looks like, try to imagine a thin layer of table salt on a dinner plate. Now add a couple or a few drops of water. Over the course of a few seconds, the water spreads out to form a homogeneous average wetness throughout the layer of salt (assuming there's enough water). This same principle is what we've discovered happening on Mars, except that it flows north and south through salt deposits over the course of seasons. The force that powers this water migration is, I believe, temperature. During the warmer parts of Mars' seasonal cycle, the water flows towards its equator, and towards the poles during the colder parts of the seasonal cycle. It may be the opposite flow pattern, I haven't read anything about it in a while so my memory is a little foggy on this part.
Awesome, as always!
0:03 "The earth is a planet" Me: "Wow! Never Knew!"
We all have something to learn from the Earth: the best protection against a raging universe is a fiery heart (and, uh... a magnetic field.)
You stay you, Earth! 👍
we could call the opposite of terraforming terrascrewing
Adrian-Cornel Borină terrafucking
wow you are an amazing teacher. i knew most of it but wow your awesome at explaining
Great to learn about this cool, new planet!
Him: The Earth is a-
Me: Star!
Him: Planet.
Me: ...
I know that the Earth is a planet, I just wasn't paying very much attention when the video started... whoops.
What about the underground oceans?
Underground oceans exist on the ice moons of the outer solar system.
GREAT EPISODE!
Another great episode.
world domination
CrashCourse >>>>>>> High School. 'nuff said.
Fr lol I'd be a much smarter fucktard if I graduated from Crash course. Shame on public education
Brillant. I saw the aurora borealis once at Loch Hourn in Scotland and it was partially cloudy and there were beams of bright light illumating the clouds around us, it was just incredible, didn't last long but what an amazing experience, we had travelled up there from Norfolk UK the whole day. We camped out there and my friend played Meredith Monk's Dolmen Music in the dark...............just incredible.
Phil Plait bro! You're awesome! :D
Is there a reason that the continental plates move at basically the same rate that our moon is moving away from earth?
they are both controlled by our fingernails
@@niconico4138 It all makes sense now
Make a crash course about Europa!
Exactly!
Awesome Phil! Thanks man!
great work guys.
I am over the moon that you are using metric measurements in this series
I have to watch this because of online school, Corona time
bro sameeeee
The animation is so cool!
One of your best and most interesting ones, perhaps because it's about Home
Planet Earth is blue and there's nothing I can do
that's was a nice song
Earth is metal. Brutal.
Such an elegant design!
aw what a nice video c: i like how the basics of geology are explained so simply but without any false/doubtful information. maybe it will make some viewers more interested in studying Earth, since there's so much to study here
as for me, one of the hardest thing in studying geology/geographical sciences is understanding the geological time. you just have to get used to it, yet it's not simple at all :
Wait, so I'm confused... why are we trying to colonize Mars when we can colonize Earth? Earth is clearly a perfect planet to live on... I dont get it?
Fame. Celebrity. Check out the entry for humans in the Hitchhiker's Guide To The Galaxy if you've never visited Earth. It's pretty depressing and I'm not even an android (though I went to school with Marvin).
“Breathing has its advantages”
Me: hmm... I wonder what they are
Using this to study prep during summer!
The video was amazing. Though I think I might have missed the bacon part. Lol. Playing it again.
Maybe we could call the antonym of terraforming something like "planetary scourgification", or "terrestrial dissonance". Any of my fellow word nerds have some ideas?
Terrapoisoning
+KSI FlapJaksLol Xenoforming perhaps. That is shaping into something alien. Venuforming could be used as a more specific name. Shaping into Venus. From another perspective, Terradeforming, distorting away from Earth; though that one is pretty awkward sounding.
TonboIV I meant a term to describe the return of planetary normalcy before human intervention, but that's pretty good. I like the specificity of Venaumorph. For example, say Mars was colonized and then terraformed. The resources on Mars are spent after millenia, and humanity leaves it to return to its natural state; or directly affected negatively by humanity after it has been terraformed (war on a planet wide scale), then the carnage results in said return to normalcy.
TonboIV venuform I mean, my bad. I misread.
terrawrecked. its catchy. I could make a song about it
In the beginning don't you mean "zero dimensional" points?
hi your channel is really great for doing homework
I love the star trek ship on you desk Live long and Prosper
i did not know ertha was a planet OWOWOWOWOWO
When earth core will cool down and what will happen?
Disciple Demon The earth's electromagnetic field generated by the counter rotating liquid iron core of the earth will disappear and the solar wind will no longer be kept at bay and our atmosphere will be slowly blown away into space. Earth will end up just as Mars is today.
Disciple Demon I don't know the time scales, but I suspect the Sun will be a red giant before that happens. :)
mihai2mn But Mars's atmosphere wasn't blown into space
***** Yes it was.
Disciple Demon that depends on how you define "cool" but to get an idea of what is involved and how to analyze it, read up on the Kelvin-Helmholtz mechanism, and radioactive decay of thorium, uranium and potassium (i think those are the major geothermal isotopes) and their relative abundance in the earth.
This is awesome!!!!!!!!!!!!
Amazing!
