Between oceans, glaciers, polar ice caps, and lakes, watery goodness covers almost 71% of Earth’s surface. And that’s pretty special - Earth is the only one of the rocky planets in our solar system with this much water. So when it comes to BIG questions, one of the biggest is where did Earth’s water originally come from? One new study says maybe…the Sun? But to get there, we gotta start a little further back. For decades, planetary scientists and astrobiologists have been building two competing hypotheses for just how Earth got so gosh dang WET.
Option one: Water was inside the Earth when it formed in the first place. The idea goes that minerals in the mantle of our ancient, primordial Earth stored hydrogen and oxygen. When those minerals melted in the natural course of geothermal activity, the hydrogen and oxygen dissolved together in the magma as water. When that magma got spewed out onto Earth’s surface via volcanoes, the water came too. Alternatively, maybe those elements stored in Earth’s minerals were vaporized by an impact from some comet or asteroid… possibly even the BIG impact we think created our moon! Those vaporized elements combined and settled on the Earth’s surface, resulting in our life-giving liquid.
But option two is an answer that doesn’t come from so close to home. Many scientists think that water was just chillin’ on comets, meteorites, asteroids, etc out in space. When these guys crashed into us…hey presto, water on Earth! Where this gets a little sticky though, is the numbers. Scientists have studied the remnants of asteroids and meteorites that crashed into us wayyyyy back at our planet’s beginning. These do contain certain kinds of hydrogen, what are called isotopes. But the ratio of the hydrogen isotopes on these ancient astrophysical bodies doesn’t match the ratio in our oceans today. To get the right ratio, the water from these crashed objects would have needed to mix with another, lighter isotope of hydrogen for us to get the kind of water we have today.

"Accounting for where all of the Earth's water came from is a longstanding puzzle, but an international team of scientists led by the University of Glasgow has proposed that the Sun may be a major source of our planet's H₂O, by way of hydrogen from the solar winds."
Earth's Water Was in The Solar System Before Earth Itself, Meteorite Reveals
www.sciencealert.com/new-stud...
"The minerals and ratios in the Efremovka meteorite revealed that, in the first 200,000 years of our Solar System's history, before the planetesimals (that's planet seeds) formed, two large gas reservoirs existed. One of these reservoirs contained the solar gas from which the matter in the Solar System ended up condensing."
Why is there water on Earth?

"...most of Earth’s water is deep underground: between one and ten times the volume of the oceans are contained in the mantle."

She has a really calming voice, quite refreshing for youtube
Like Morgan Freeman
Either theory means that water isn't that rare and as long as a rocky planet maintains an atmosphere means there should be lots of water planets out there
There are moons that have water.
Love to listen Maren. Her voice is so calming. 😌
THE MOST astounding fact is not all the water we have on the surface of the earth, but the incredible amount of water that we now know there is around 400 km underneath; it's estimated that it could be whether as much as that of all the oceans combined or even 3 to 4 times MORE water (ok, it's not liquid water, but a kind of a highly compressed mud, that recycles with the tectonic plaques' movements in a kind of never ending process).
Very true. I've seen estimates of up to 100 times the amount of surface water. The accepted dogma has been that below a kilometer or so beneath the surface the pressure is so great that even the poor spaces are closed, and there is essentially no liquid water beyond that depth. However, the Earth appears to have formed more like a cosmic-sized geode with more water than anything else. The researchers at the Kola borehole in Russia, and also those at the KTB borehole in Germany, remarked that the geology books would need to be rewritten due to the massive amounts of water they were finding with depth.
We have too much damn useless water on earth. Wish we could get rid of some.
@@jedahn - Haha! Stupid water..!
I love now natural and enthusiastic she is in these videos
Great video ! Super informative
It was me. I spilled a bunch of bottles of water on the Earth a bunch of years back. I've been looking for a big towel to wipe it up.
There are three main hypotheses on the origin of Earth's water:
1). Earth always had water trapped in its mantle, which cooled into rock
2). Asteroids delivered the solar water via many collisions
3). The Great Impactor Hypothesis, where Theia delivers the bulk of the water
Eath's water probably came from multiple sources.
"Where there's water, there's life." That's why we NEED to go check out the icy moons of our gas giants!
Water is sterile.
@@ipissed pure water is sterile. Water that comes in contact with the rocky core of a moon is not.
@@rickseiden1 As far as we know the entire rest of the universe other than Earth is sterile. Did you do science class yet? What grade are you in?
@@strangetaste824 How dare you belittle life forms in the universe that don't depend on water. I don't know if there aliens in the universe but if there are they must comply to my expectations. You see how that works kiddo? Racist.
That statement is false. There's no life on the Moon or Mars that we know of, but I agree that investigating Europa and Enceladus is critical.
We kept discovering and learning evolution of life on earth and thank you for the whole new experience and support ☺✌
Seeker is just amazing
Nice video.
First time watch early 👀 thanks for kindly make thisvideo
This just in, our planet was built with stuff from _Outer SpAcE!!_
You can't make that leap that where there is water, there is life!
Agree 100%
Wow
Hi Maren! 👋🙂
this refers to river ganga coming to earth
Reminds me of Moses striking the rock producing water
Not me drinking water watching this video...
Where there water, there's water 😂🤣how about that theory 😂
Great vid but quick note; every time "mag-ma" is spoken, it must be said with accompanying finger air quotes a-la Dr Evil. Thnx
Europa/Enceladus is thought to have more water than all the Earths oceans combined.
Yup
Earth's water came from Saturn's rings since water in rings matches with water on earth. Earth originally orbited Saturn before its capture by the Sun and was transformed from brown dwarf to gas giant due to mass loss. Physicist Wal Thornhill talks about it in Saturn Earth Connection video.
All wrong.
The reality is likely a combination of both views.
There is water above and below the water above is held in place by the firmament
As you mention in the video, there is strong evidence for large bodies of water to have existed at one time on Mars.
Nevertheless, the rovers have not found a single shred of evidence for actual life to have existed at any time on Mars.
We do not yet know scientifically how life arose on earth.
Its too simplistic to say “where there’s water there’s life”. This is merely a statement faith and not a scientific statement.
Everywhere on earth where we find water there’s life. Deep underground. Near hydrothermal vents. Everywhere.
Mars rovers haven’t really been looking for microscopic evidence of life. Only perseverance has really had the equipment to find something
Its a hypothesis based on observation not faith. That's why scientist test it wherever there may be water...
@@granodiorite9032 There is no scientific proof that life emerge from water, so it's indeed a faith based statement.
Besides on earth, where there's soil, earth or land whatever u wanna call it, there is life just like water
Idk if u guys have heard of the bible There you know the origin of the universe and how humans became to be
@@mab0738 Who said "life emerge from water"?
Its an observation on earth. Where we find water, we also find life.
Без воды никуда
Next title: Did Human Crash into Earth from the Space?
I mean... wouldn't it just makes sense that it's a combination of both? The real question is what was ratio between the original gravitationaly bound material to h2o laiden impact events and are there any other contributors we have yet to identify.
How about a video about web3.0, the IOT, agmented, virtual and regular reality and 5g etc. and how a mesh planned between all of these techs will create a new way of life?
Why does it have to be one or the other? Borh methods probably contributed some water.
Thanks 🙏
Audio is normalized too low.
Condemnation!
Sweet Spot, moving away, soon no Water
Like Mars.
She is so cute for reading the line..
"So, we know, where there is water there is life."
First thing that came to my mind is "we ASSUME where there's water there is life".
We keep seeking things we can see and we acknowledge.
But like Tesla said start studying what we can NOT see. There is life where human's wont think to look for it.
She should have said where there's water there could be life or may be life.
A new video that doesn't talk about women and feminism! AMAZING
Planet Proper WaterBalls
0:40 that's what she said😅😅
But why mars lost its water while the earth didn't?
That's still coming,, but relax, we won't be around at the time.
Well it probably did but whatever stripped Mars of its atmosphere long ago (maybe the magnetic Feild weakening) made it to where all of the water was evaporated into space
@@lolok1099 Yes, as Mars's core cooled down through the billions of years, the magnetosphere disappeared.I guess at the time Mars had water oceans, it was in a Goldilocks zone.more than Earth's at the time. I think the key to terraforming Mars lies in researching the possibility of reheating the core by systematically thickening the atmosphere with carbon dioxide and creating an artificial magnetosphere by future tech..(OK, I'm like 2100'ish now) 😊
Water is the most ubiquitous substance in the universe, and all celestial bodies were formed in water... which is why so many have water inside even now. This includes comets. Mars is too small and lacks the gravitational pull to retain water vapor. Same with our moon. Both once had much water inside and out, but without adequate gravity to retain it, the water sublimated or vaporized and was rapidly lost to space.
@@tonyelsom6382 - How would thickening the atmosphere and creating a artificial magnetic field reheat the core?
From centuries, we humans, are looking out and want to think & believe and asking quetions & answers , are we out here alone or is anyone out there too. May be we get this answers to this quetions in the future years.
Maybe... A higher power that made everything perfect enough to live? Maybe! A lot of accidents lmao...
😀
There is also another study that says it has found evidence that the water was in the cloud that formed the earth those millions of years ago!!! You guys should hurry and do a video on that!
Where did the oxygen come from?
@@jedahn the oxygen was present in the cloud as well, but due to the chemical properties of oxygen it was bound to many off the other elements present; iron, aluminum, etc.
The oxygen in our atmosphere has been shown by the fossil record to have occurred from a chemical reaction in the primordial seas which caused the dissolved metallic oxides in the water to precipitate the heavier metals, releasing the oxygen in the process.
"Almost certainly not alone in our Universe" kinda Switching from Science to Preaching.
earth got wet cuz sun was hot... mood
Yes. How else would you flood it entirely?
The Earth was formed from water. The crustal minerals are crystalline. They were created in water like all crystals. It's also why all rocks have a large amount of water in them.
You know, it doesn't have to be an OR. It could be an AND between two or more of them.
We don't know that where there's water, there's life, but maybe we will know more a bit further on. I suspect ALL planets have water. I wouldn't take any bets on whether they all have life, though. But since we are more likely the norm than the exception, many probably do. Intelligent life? Not so much, so far.
And since we can't even figure out where the majority of our water came from, I'm not all that sure I buy the "if there's oxygen, there's life" argument either".
It is so confusing but the theory that water was inside earth seems more legit
Yeah and how did that water get there
@@ricksanchez8469 the way she explained
😂
The bees brought water here🐝🐝🐝
Why is the planet called "Earth" when 71% is covered with water???
Maybe the reason we call it “Earth is because we live on the earth and not in the water. We’re not dolphins 😀
Yo
Seeker
The constellations were best at that time creating our solar system. Space at this place was full with all particles needed to create existence as we know it. Randomly all gravitational forces held the constellation of the new born planets to its star in a constant. The core of earth that was supposed to become a star was covered with debris that were attracted through a strong magnetic pull of the core. All pieces that formed earth were from different elements. The cold temperature of space in the surface and the hot burning core of earth created through evaporation clouds, that then rained back to earth as water, creating lakes, sea, and ocean. Which particles exactly are responsible for life on earth, we don't know yet.
All science fiction.
Simple answer, we're in a simulation and the creators modded in the ocean
I am not expert on PC coding but from IT stories I would say that anything else would be easier explanation :v
Sooo earth was created by EA, and the modding community had to fix it? Kinda believable actually…
@@LongDanzi exactly
@@LongDanzi we got nothing better to do so we post comments on such videos..
Water is created in the solar wind constantly by the electron-proton fusion into Hydroxide(Oxygen)-Hydrogen H2O process.
Lol
What’s funny?
LoL
What’s funny?
Our earth is broken pieces of sun which must have collide with other Star..lot of stuff we don't know ..still we are finding things about Earth
Water came from the firminant from above the earth read Genesis all the answer is in there
Water came from ice caps. I assume the Sun wasn't that close to earth during the time and the ice caps covered most of the earth. As the Sun got closer to the earth it melted the ice over millions of years, turning it into the oceans and the seas. Where the ice came from is the biggest question humanity has to answer.
I am first please pin me
I'll pin you against the wall.
@@perplexingperceptions8888 lmao
Yes it did... It's Biblical .. and seen in the Earth's reflection on the moon.
The Earth was formed in and of water.. That's gotta sting a bit for all who consider the scriptures to be ancient myths for uneducated and needy people.
How much is a million C? Also a down vote for assuming everyone speaks metric. 👎 I give both when citing measurements.
this channel will believe anything except for what's in the Bible.
