I just finished watching the classic Doctor Who story "Inferno", like a minute ago. In that story, they drilled through the crust and found green goo that turned people into werewolves.
I did not dream of digging to the center of the earth. My single-digits self thought I could dig from my grandmother's house in Virginia all the way to England to meet Paul McCartney. It was the 80s. My cousin dug with me, but at some future point HER tunnel would diverge so she could meet Bon Jovi in New Jersey. Anyway here I am, still in the US. My hole in the ground only never made it deeper than 2 or 3 inches.
not even a foot? doesn't really matter if that particular effort may not have been perfectly conceived, maybe there were some gold coins just 1 or 2 feet down now you'll never know !
Oooh, you should have kept going. It just might be that Mr. McCartney was digging a hole in his back yard hoping to meet you! So you would have met half way!
Semi-interesting to hear the "what" answered by this video, but I'd be more interested in a video that goes into the "how we know" (how these discoveries were made, and how confident we are about their accuracy). Seems pretty remarkable that we apparently know all of the different elements and physical behaviors of these elements at various depths despite never directly reaching even 0.5% of the depth we claim to describe in this video. What tool(s) were used to make these discoveries and how do they work? That'd be an awesome video!
The same way we know the composition of stars. Electromagnetic waves and even sound waves behave differently depending on what the medium they are traveling through, is composed of.
The Royal Institution do a series of lectures every Christmas and they did one about 20 years ago on the history of how we gradually started to understand what was in the subsurface. I'll have a look to see if those lectures have made their way to their RUclips channel.
And then a few seconds later, we have "Outercore", "Innercore" and "Mantie". Production quality is through the floor on this one. Bad SciShow. No biscuit.
I just love how Hank's humour adds to the storytelling, making it a nice experience absorbing 15 minutes of geology terms I've never heard or dreamt of.
I would love for you guys to cover the rift that is splitting africa in two. I have I don't know five thousand questions about that- Like when did it start? How fast is it growing? How many years would it take for the ocean to fill in the gap? And those are just three of the five thousand questions I have. Thanks Hank et al, love your channels❤
That's a very interesting place biologically speaking, too! There are around 2,000 known species of African cichlids, over 500 known species in the three largest rift lakes (Victoria, Malawi, and Tanganyika) alone! The lakes are very deep, so likely there are many more species that haven't been found. No other genus of animal has evolved into so many species so fast.
"Geeze, I wonder why it's so hot down here!" "Must be the extreme pressure!" Meanwhile the mega clowns roaming halls of dead gods, warring in the charred wastes of the the circus:
At 5:13, you show a still of some fossils labelled "trilobite fossils" but the fossils shown are actually _ammonite_ shells (spiral-shelled snail like creature unrelated to trilobites), not trilobites. I'm surprised you guys would make a mistake that big.
15:05 when I first heard this theory in college close to a decade ago, i always assumed it would be that the inner-inner-core is concentrated in elements even heavier than iron, since the leading explaination for the core being iron rich is through differentiation early in formation. If iron can sink to the center of the earth because it is too heavy, then surely platinum, lead, uranium, etc can do the same.
I watched Cleo’s video when she published it, and it’s really interesting to compare and contrast with this one. There’s just still so much unknown that far down
As a geolgist, the nature of the minerals deep in the earth will always be a frustrating problem to solve. We can't recreate those conditions in a lab, so while we know the rock composition, we don't always know the properties of them. Take bridgmanite, it's the most common mineral on earth, making up most of the lower mantle. We don't know what the properties of it are, because there's no way to look at it. Any grains of it that are pulled to the surface regress to a different state and we can't dig that deep. One tiny grain of it was found, but it was too small and rare to tell us much.
Really cool video! As a geologist it's lways nice to see geology getting some love. Just at 6:03, you wouldn't reach the mantle with 10 km of digging in the continental crust, on average you would be looking at 30-40 km
I freaking love this channel. When you guys really want to dig into the science(heh). You really go all in, and you explain everything so well. XD Keep it going, and here's to another year!
8:40 my favourite analogy for this type of solid is silly putty. Elastic enough to bounce like a rubber ball, but will flow viscously if left to sit on a table for an hour or so.
5:11 "all fossils were once living organisms... or the products of living organisms, like fossilized poop" Isn't fossilized poop also "once living organisms" in its own way?
hey so about the ringwoodite... @OctopusLady talked about this apparently in the geological sense water just means hydrogen, as in the "water" is referring to hydrogen rich molecules not actually water, so while some is probably trapped in ringwoodite, there may have been a misunderstanding. Which one of your sources did you use to find its all ringwoodite?
So when water gets chemically bound up in rocks or molecules, it can do so in a few different forms. With ringwoodite, because of the high temp and pressure, it's bound up as a hydroxyl radical - a hydrogen atom and an oxygen atom bound together. It's formed by the reaction of olivine and water at high temp + pressure. Technically it's not *water* in the sense that it's not H2O, and it's a component of the crystal structure, but it can undergo processes that reform the water and cause chemical and physical changes to the mantle. So it's considered a sort of reservoir of water - just not in the traditional sense of "large pool of liquid". (Source: www.bnl.gov/newsroom/news.php?a=111648. It links back to the original ringwoodite paper as well.) Water in a geochemical sense does *not* just mean hydrogen, though. And that's speaking from both a chemistry degree and some experience with geochemistry, specifically. I'd recommend looking into hydrates and hydrous minerals if you're interested in more examples (including ones where it *is* H2O being bound up in the crystal structure). Will say I can't speak to SciShow's sources, though, and I didn't do enough reading to find if they think the reservoir is all ringwoodite or not.
6:25 Gabbro is to basalt as granite is to rhyolite. It isn't a mineral, it's a rock. The crystals you're describing would likely be pyroxenes, amphiboles, and calcium feldspars. Also gabbro is already used as countertops material, it's maddeningly called black granite.
What a great video! Thank you from the mysterious inner core of my heart for creating amazing resources that keep me (Earth science teacher) up to date on current research AND providing fun content to share with my students.
Is no one going to point out that the fossils shown in the picture are ammonites, not trilobites? Trilobites are the li'l guys that look like isopods with horseshoe crab heads.
Wehn i was like 9, my older brother wanted to dig a hole to china. About 2 months after he started, my parents could stand in the hole and be all the way in the hole standing up with the walls taller than that. The whole neighborhood started helping build the hole. It eventually got filled by the city again because we lived on a military base and they didnt like the hole.
You were talking about what we'd see as we drilled down but my first thought was that it would be dark since you're underground. So you wouldn't see anything. But that got me wondering, at which point would it be deep enough for the rocks to start glowing from the heat? Think about it. It's pitch black underground because there's no sunlight. Up to a certain point. At a certain depth underground would be full of light.
Very sloppy SciShow. Those are not Trilobite fossils at 5:20 they're Ammonites, which were a type of cephalopod whereas trilobites were arthropods. It's like mistaking squid for crabs. Send your scriptwriter/editor back down into the salt mines until they repent for their sins !
8:59 how would the constant flow of the mantles currents affect the drill? After a few years it should have shifted enough to create some sort of force on the drill right?
Those two giant "earmuff" lobes are intriguing. They've just been more or less static like that all through geologic time despite (I assume) convection going on all around them? And do their shapes somehow dictate or channel zones of upwelling, and concurrently the locations of hotspots like Hawai'i and Yellowstone?
Some geologists postulate that the very center of the core accumulates enough heavy radioactive elements like uranium and thorium to sustain a chain reaction. Our planet's core could be an actual atomic reactor.
I will venture to say that east west oriented inner core is from uneven irregularities in the crystal structure between it and the outer core and the pressure so that the pressure squeezed it and it locked into place like a random nucleation and defect
I watch some of Cleo's videos and saw the one about Earth's crust in my suggestions but wasn't going to watch it. Now I'm curious what is different about her video and will watch it. I like SciShow because I don't see the glaring errors in science that I see in some of the other RUclips channels. Now you're Insanely Curious I bet 🙄.
