While the Earth's oceans are known as five separate entities, there is really only one ocean. So, how big is it? As of 2013, it takes up 71% of the Earth, houses 99% of the biosphere, and contains some of Earth's grandest geological features. Scott Gass reminds us of the influence humans have on the ocean and the influence it has on us.
Lesson by Scott Gass, animation by Sandro Katamashvili.
The 99 percent biosphere thing blew my mind
Me too. Now I gotta find a brain tissue...
rochelimit's hangout mine too!
rochelimit's hangout that's actually just a lie made up by scientists because there are only 8.7 million life forms in the world and plenty of which are on earth
S let me guess. Trump voter?
It's not a lie, seriously, you say that, but people still haven't explored the entire ocean, actually, in 2016, we only managed to discover about 5% of the ocean, it's so big, but so big, it must have so many fucking lots of fucking millions of fucking creatures, m8!
36 Muricas? Thats a lot of freedom
That's a lot of fat fucks
Thats alot of Donald Trumps
+Le Blayout that's a lot of debt
+Cola Phoenix lol
LMFAOOO
Why is the United States the default unit of measurement with water?
+Colonel Reid AMERICA FUCK YEAH
Murica. Nuff said.
Because 'Merica is the only country that delivers freedom from "sea to shining sea." 🇺🇸
***** Although that would be true in most cases,
1. I intended the question to be rhetorical and humorous and
2. I AM NOT AMERICAN. TRUE NORTH STRONG AND FREE.
+Terra Titanius They used the metric system, so the world could understand, and compared to the USA, so americans could understand.
Its so annoying how people think that throwing just ONE can of soda in the ocean won't affect it.
They're right, it won't.
+Aaron Cruz LOL
It won't. Did you watch the video?
+Crownie it won't. however if every one on the planet decides their one can won't hurt...
it wont. but if every man on earth - or at least on a country - thinks like that, it will definitely affect the ocean
Fun fact: More people have been in space than there have been to the bottom of the ocean.
yea considered no one have been at the bottom of the ocean
***** Not true. So far 3 ppl have been @ the bottom of Challenger Deep.
Abel Lawliet Fun fact, more people have become lost on the way to the moon than have had sex with me .
Mad Though instructions not clear. Dick not found.
+Mad Though That's impossible. Even if you've had sex with 0 people that implies at least 1 person has got lost on the way to the moon, which is not true.
No one ever mentions how thin (shallow) the ocean really is when the whole globe is in view. Compare 11km, the single deepest bit of the ocean, with how 11km would be seen sideways. Considering Earth's diameter is less more than 12 thousand kilometers, 11km is thin as the thinnest wrap.
Yeah, there's a video of that on Vsauce
Well, the video does say how deep the deepest part of the ocean is.... I don't think we need someone to condescendingly tell us that the ocean depth is small compared to the earth lol
ted Ed is homeschooling me
Dude you need to pay the fees for getting schooled
samuel okerson yep!
Even now because real schools are closed because of the Coronavirus
Their homeschooling all of us now...
quarantine 2020 be like
only 4% of the ocean has been explored by humans, yet 5% has already been destroyed. :C
***** I want to throw something at him.
How about the can that he threw into the river?
***** nah, something painful.
+TG CoffeePlus I honestly thinks the damage of making your computer is roughly a thousand times larger that that.Please always think about your error before denying one's
+竹珍黃 I don't get what your saying but this what I think "your saying that the materials it takes to make a computer is 1,000 times worse then what humans have done to the ocean" HUMANS ARE A STUPID SPEICES WE MADE OVER 50% OF ALL SPEICES EXTINCT WE DID HUMANS DID
"Thats billion.. With a B" - Walter White
Billion with an F
Why are you using America as a reference point throughout the video, but decide to use metric units like Kilometers and such?
Mike Dang metric system is used worldwide
+Loti Bajrami yeah, but not by the states

That's a non-sequitor.
It's typical US narcissism. That's why.

I don't get it.
he says billion with a b and billion does start with b not any letter, so that person above is just showing sarcasm
Soo that's how you write billion ... What have I been doing all my life?
Some could hear million
And it's also really annoying to cross in minecraft :P

*watching 17 videos abt ocean in a row*
Me: OK fine, that's enough
RUclips ads: HOW CAN A SINGLE BRACELET CLEAN THE OCEAN?!?!
but the real question is: how deep is your love? lol
+Killer97 its like the ocean
Can it be above sea level?
+Killer97 Ask the BG's
+Killer97 deep enough that you see adele rolling there
+Killer97 deeper than molecule deeper than atom deeper than dna deeper than proton deeper Than neutron deeper than nanometer deeper than -99999 nanometer
Great video! I'm so glad that you took the time to remind to us about looking after the ocean and helping it so it can continue being awesome. That's very important!
Its so big its practically incomprehensible... And then you realize we live on a single planet, in a single galaxy in the universe, and that our nearest star (which isn't even close to some of the bigger stars) is 1.3 million times bigger than the earth. Its amazing.
Planet Earth..........more like Planet Ocean____with just a touch of Earth.
that's a cool thought, thanks!
@Chris Qiu Exactly. There is very little water in comparison to earth.
Still, it's 0.02% the Earth's mass.
Wait how can a waterfall be underwater?
Like cold water moving underneath warmer water
That is a lot of water. What happen if someone would have to drink all of that water😂😂😂😂
Mynson Anderson idk
Chris Sherman Yes, but an underwater waterfall is nothing more than denser (colder) water flowing downward over an edge. It would be invisible.
Chris Sherman just ask spongebob
Whoever made this planet must be unimaginably powerful.
The ocean is big enough to drown all of us without even raising the sea level
Ikr
Humanity knows more about outer space than the depths of Earth's own ocean.
+donbasuradenuevo it is easyer to know and to get on space than the depths of the ocean...
we dont even know for sure what space is composed of or the things around the solar system and we cant even leave the solar system, how is that compared to the ocean?
Constant references to the size of the USA
OK ?
+AAron Thom its a good tool cuz everyone knows the size of usa
+
+nacha laica that's so egocentric
+Guy Randomized yeah but its still a good thing to compare it to
The water of the world is worth $5,618,100,089,501,550
+MrSuperfluous1 what if you had this amount of money and aliens stole the water? huh
This guy is getting so upset over the word and, I'm laughing so hard
A recent visit into Challenger Deep, as discussed on NPR, found what appeared to be the presence of plastic waste. The scientist being interview hastened to add it was not a lot, but there it was😢.
Will someone please explain to me how this mountain range can be 65,000 km long when our planet's circumstance is 40,000 km
+Jesse Jacobs circumference is of a circle that is one side of a sphere because our earth is spherical it's possible to have a range longer than circumference if it's not in a straight line.
Thanks! I also just realized I totally misspelled circumference. This is what I get for typing on my phone.
+Vinay Aggarwal great!
+Vinay Aggarwal still, if it were to go around the equator, it would cover the earth 1.625 times. There must be some weird calculation involved of the data is straight up wrong.
+Yanthir who's to say it doesn't wrap around the earth like a screw? Where there are multiple coils of mountains.
They forgot the mention that the ocean accounts for very little of Earth's volume. The ocean only goes about 11.03km down (Challenger Deep @ Mariana Trench), but on sea level, the center of Earth is 6,371km away. Far, far, far more than the oceans volume. So, Water goes to 11 km; land goes to 6,300 km. See the difference?
In simple perspective, Earth is 1.8321 TRILLION 1,083,210,000,000 cubic kilometers in volume, and the ocean is just 1.3 BILLION cubic kilometers or 1,300,000,000. In ratio its about 130/10,8321.
Land doesn't go 6,371 km. Land, as we call it, only goes down to 5 - 70 km. Below that's it's hardly land. The asthenosphere is a sort of soft solid, while the mantle and outer core are completely liquid. The inner core is solid though, but that's just because of its density.
Uh 1.8 or 1.08?
These vids teach me way more than school ever can
ikr
When I was young,I thought the end of the horizon is a big waterfall 😂😂😂
I was hoping for a measurement of "If the Ocean was a planet" I know the surface is 70% ocean, but what percent of Earth's mass is ocean. I am disappointed that this question was not answered.
The Mass of Earth is 5.97219e24 kilograms
The Mass of The Oceans if 1.3e21 kilograms
So on doing the division, you get 4.59e-3
Which is 0.021 % of the total mass of Earth!
I hope that answers your question. :)
that does help thank you.
Dude when I come home from school I come straight to my phone for this high quality content. I think everyone agrees with me right?
Same here bruh
Remarkable how relevant this seems, 6 years later!
-Uses 'Murica as a comparison unit
-Measures everything in European units
technically speaking, the metric system is used world wide. not only in europe. canadian here ☺
slice n' dice Except in the United States.
+Paladin Luke yup
+Paladin Luke "European units" is the metric system and it's the scientific unit system
The-guy-Zach Well you get the point.
Ted, if you ever need some help with animations I'd be willing to draw some detailed shapes and pictures or landscapes :)
That was a very deep lecture.
Manny: HOW BIG IS THIS OCEAN?!?!?!
Sid: water water every where
Ocean holds many secrets in it we never imagined
I love the ocean - it contains my favorite animals and I would love to see it every day, just hear it and see it's vastness. Videos like that give me an uneasy, almost painful feeling. How could humanity screw that up so bad... It'll survive, yes. And It's adapting. But it is truly tragic what has already happened and will happen for quite some time until there is something like a global evolution of our minds and I'm afraid I won't be able to witness this in my years to come on this planet.
now things only became worse...
TED-Ed has gotten a lot better.
The fact that so many underwater species are undiscovered gives me hope that (the) kraken exists.
I loved loved loved this! It kept me riveted the entire video. Good job explaining everything. It was done in a way that was easy to understand and at the same time entertaining.
Thanks... I am subscribing
2:36 "The Ocean contains the world's lAUURgest mountain range" LMAO
The examples in the video were for the US, here they are for the UK. All the oceans' water would cover the US 130 km deep, the UK would be under 5298 km of water. The square area of the water would cover 36 US's or 1444 UK's. This is based on square areas of 244,820 and 9,826,675 for the UK and US; I used a multiplier of 40.138. Personally, I think they should have used Pangaea for comparison (no flag). Have a great day people.
I found this videos so interesting and it likes me the way that makes you think about the topic it's talking about, and the last part make you reflect about the way we affect the enviroment.
Why do you count that hawaiian mountain from the ocean floor but you don't do the same for everest? Yeah, there's continental land attached to it, but that can just be considered a flatter part of it's mountain range.
yah
It did look again
To think that we've explored less than 5% of the ocean- yet people seem to assume everything in the ocean in accounted for.. Goes to show how presumptuous humans can get when it comes to "what they know"
Very VERY true. Thanks for pointing that out.
its not that simple, unfortunately.
And are you doing anything about it? No. Don’t act like you’re perfect because you acknowledge it and do something if you actually care instead of talking about it in RUclips comments go and do something.
I wonder what percentage of space have we explored .
now that you have a vague idea of the scale of the ocean, consider this: in 1 cup of water (half a liter) there are more molecules of water than there are cups of water in the entire ocean. 1,300,000,000 KM^3 times 1,000,000,000,000 liters per KM^3 times 2. that's 2,600,000,000,000,000,000,000 half liter cups. molecules are tiny
Subtitles are ahead from voice....only ted ed video I've found any mistake, after watching many videos....👍👍👍
How big is the ocean?
TedEd: Makes a video.
Me: It's very big 🙂
After watching this video, I really feel bad for the ocean and its marine animals and life in general with all the ways we are polluting the water. Specially in countries like India. We need to do something about it, or life will go down in the drains.
May I ask you a question?
Is the Occidental World having some sort of grudge with we Indians? It seems to be as if we are the only one on this planet who have caused aaaallll sorts of bad things like pollution.
What drains?
@TED-Ed You might not read this, but the english subtitle is not in sync with the video; it is ahead of the VO.
99% of the biosphere? You really think so? Some seas have been depredated to an extended that is, in some cases, beyond recuperation. Mankind took down some digits from that 99%, I'm sure. Really liked the ending! We ALL need to take care of the only Earth we have.
every video about the earth eventually devolves into an environmental "save the ocean" video
er, devolves? honestly, DEVOLVES?
Milind Tripathi what's wrong with the word "devolves?"
You_just It implies that they become the worse for talking about it.
Milind Tripathi I mean, I love the ocean more than the next guy, but I came here to find out how big the ocean is, not how to protect it. I'm fully aware of all the pollution in the ocean.
@@you_just most people don't care about the environment, that is why we should bring attention to it, pretty simple, and it doesn't make the video worse it gives the message"the ocean is big and important" it's meaning. If you just wanted the question to be answered you could have just googled.
2:35 that voicecrack XD
I was in gifted learning about oceanology and I seem to learn somthin' new everyday!
Nevermind, I just realized they were a distant school of fish, but the way they were arranged and the compression of the video made them look like numbers or letters.
Such a deep and inspiring video...

Melissa Don't.
Melissa that’s not funny. It’s a serious issue.
Why do people laugh? That's a serious issue, don't joke on it, or everyone on this planet might die.

Wow great video Scott. Really puts things into perspective.
Please fix the captions! They're timed incorrectly!
man the ocean is some freaky shit
+jordanana hulbert that what she said
+cixlo wow, that was an extremely bad "that's what she said" joke. Better luck next time
+Kyle Shadeck i think it wasn't a joke, it was meant to be "that, what she said"
what about the Marianna trench?
OH. ok then
Some Random Person In fact, Challenger Deep is the deepest PART of the Marianas Trench.
It's Near My Country (The Philippines) 🇵🇭🇵🇭🇵🇭, And It's Also Near Guam
OMG! This video is awesome, my teacher shows me and it’s nice! Good job.
Thank you for that snippet at the end about environmental sustainability
I believe the ocean on Europa is as massive or perhaps even more massive? It's certainly much deeper. I think we will find life there.
Cooks With Spoons nah there’s no life in the ocean
How big is the ocean?
BIG
The wave sound is so soothing
I love the message at the end.
"Let that sink in" Hehe... sinking jokes...
1 advice to video makers .
The sun does not revolve around USA.
Stop referencing distance ,volume in terms of USA.
I don't understand a Damn thing.
Akshay Bhardwaj lol
Odd. Thought you foreigners knew it all and it was Americans that are morons.
That's ur problem
theres something called LEARNING
@@12icki there is something called "use the universal misure unit" in science
I feel the need to explain the biosphere comment. Biosphere refers to CUBIC or 3D space that CAN house life. Because every drop of water in the ocean CAN hold life, like bacteria and algae, all of the water in the ocean counts as the biosphere. In contrast, not every bit of land/air counts, only what’s in the dirt and up to the canopy layer. So it makes sense then that the ocean is 99% of the biosphere.
In fact, life in the ocean only accounts for a small percent of bioMASS, or mass of life
Thank you for the message at the end.
Fun fact: More people have been in space than there have been to India.
Depends on what you define as "space", i agree tho
More people are in water than are eaten in Sri Lanka
Since mt everst is on land just like hawaii, couldn't you say that the land continues to the ocean floor? That makes mt everest the tallest.
mt everest isnt surrounded by water, so no it would still not be considered the tallest.
from sea level mount ev is the tallest
from the core Chimborazo is the tallest
Why do ppl think Mt Everest is the highest... I dont know why does it matter if something is above sea level when we live in a kind of spherical planet so hight should be measured from the center of that sphere which makes Chimborazo the highest
That voice is so calm
I am not worried that my children won't go to school when TED-Ed is homeschooling them.
"What we know is a drop what we don't know is an ocean" - Jonas in Netflix Dark
That's a great line.
I don't feel bad wasting water anymore... Lol jk I still care
Earth having only one big ocean sounds like common sense but I really haven't thought about it until I heard of it here, and it just clicks, "Oh hey, it's true! We just named the regions, but it's all connected to make one big ocean!"
"What we know is a drop. What we donot know is an ocean" - Dark

I need to learn the metric system.
It's easy! It's all zeros.
TEEEEAAAAAAACH MEEEEE!!!!
TheCarlc1434
Length: We'll start with the most basic unit, the meter. Marked by M.
Divide it by 100, and you get a centimeter. There are 100 centimeters in a meter. Marked by CM.
Divide it by 10, and you get a decimeter, or 10 centimeters. There are 10 decimeters in a meter.
Divide it by 1000, and you get a milimeter, or 1/10 centimeters. There are a thousand millimeters in a meter. Marked by MM.
Multiply it by a thousand, and you get a Kilometer- A thousand meters, or 100,000 centimeters, or a million millimeters. Marked by KM.
For example, the length between LA and NYC in one straight line is about 3950 KM.
Weight:
We'll start with the Kilogram, Marked by Kg.
1000 Kilograms are one Ton.
Divide a kilogram by 1000, and you get a Gram, marked by a lower-case g.
I know:
Femtometer(Fm),Picometer(Pm),Nanometer(Nm),Micrometer(|um),Milimeter(Mm),Centimeter(Cm),Decimeter(Dm),Meter(M),Decameter(Dam),Hectometer(Hm),Kilometer(Km)
1Fm=1^-15 M
1Pm=1^-12 M
1Nm=1^-9M
1|um=1^-6M
1Mm=1^-3M
1Cm=1^-2M
1Dm=1^-1M(1M=10Dm)
Meter(M)
1Dam=10M
1Hm=100M
1Km=1000M
They also use other units of measurement like:Feet(ft),Yard(Yd),Miles(???),Inch(???) or Light years or something...even Exameter(bigger than light year)(i think it's something)or other...
This day a legend was borned.
Why are some people pissed off about using America as an example? It shows the same data and information as say, he used Australia. It just doesn't make sense.
I bet it's not as dense as a nucleus
How Deep Is Your Love?
Now think about this, even though 99% of the biosphere is beneath the ocean, our 1% chunk still managed to affect it the most.

I would have liked to see a a 3D map of earths surface drained of all its waters to asses for my self how the geographical features look like under water. Why educators are always patterned to give only one side of a truth: yes, water makes 70% of planet earth surface.,and the video said it comprises 360 billion cubic kilometers .that's fine.But it failed to mention How much is the ratio between the bulk of oceans compared to the bulk of earth itself? i think it is a negligible fraction. How deep the waters would be if the earths surface were evenly planed with no mountains or ridges or ravines or islands ? 3 km /4 km ?
+미셜비 It said it would cover an area as big as the US under a depth of 132 kms.It limited the area to the US only not to all smooth earth. Does the stratosphere reach up to 132 kms? NO. How deep is the deepest point in ocean? Its 11.6 kms (in the pacific ocean) ,so the average depth of all the oceans on the whole surface of earth would be some thing between 0 - 11.6 which would result in a constant definitely below 5,8 kms NOT 132 kms
+محمد سعيد حمد
I'm quite sure they made a mistake on factors of 10. 360 billion would put us all under hundreds of km of water!
Let's say they meant 3.6 billion km^3
surface area of a sphere is 4π r² for the earth r is approximately 10000 km. Depth would be volume divided by surface area.
(3.6 * 10^9) / 400000000 π = 36 /4π km = 9/π km
So assuming they where out by a factor of 100 we would be under a 9/π km of water if the earth was perfectly spherical. Slightly under 3 km.
Correct around 3km is the depth. Where did it all come from? I think it juiced out of the earth interior , being under pressure from thousands of kilometers thick layers of molten and solid rock. The best place for it is to be in the crust and above. Thats the reason why there is no water on Mars. All its waters are still trapped in the whole mass of the planet. Not that it lost it to space
محمد سعيد حمد someone on on another post says they said 1.1billion and 360 was something else wiki says 1.1 billion so it looks like it might actually be more like just under 1km . Both 1km and 3km sound about right 300km though dosn't .
+محمد سعيد حمد Fun facts to say here: we(humanity) don't know how the ocean acctually looks geographicaly speaking in the bottom , why!?: because we know about 4% of the ocean and 98% of the moon.
For more we know what it is up there in the space almost no one knows what is in the bottom of ocean of our big and blu planet Earth.
soooo Mermaids?
We will have mermaids at 70%
I'm getting in love with this channel
I always assumed these TED things were something more than high school presentations.
But of course, the earth couldn't have possibly been subject to a worldwide flood.
If you bring the underwater chamber they discovered recently, scientists says that it could cover the whole land.. Just saying..
Jerome Quejano Lol I know. I was being facetious.
Jerome Quejano Where can I read that?
no it could happen....but without leaving any trace in the geologic record....now that would be impossible.
terminat1 then why are different fossils in completely different rock layers. And these layers are dated much older then a couple thousand years.
Of course the examples have to be america
there's like 130 something more countries
Hugh Marshall and?
They make it so easy to soak up.
The voice crack gets me every time.
thalia was busting on me
angel maldonado Your comment makes no sense.
I was the 1,000,000th view of this video! #LoveTED-ED
The ocean and water in general are truly great!
_Try to convince IGN that there is not too much water_
Aww, I was hoping it would tell us how deep the ocean would be if the earth was perfectly smooth all around.
