  • How Deep Down Is the Earths Core?

    8:59

    How many layers does the Earth have? Have you ever wondered what lies beneath Earth's crust? Well, our planet is like an onion - with loads of different layers. The Earth's crust is like a hard-boiled egg's shell - thin and tough. It takes up less than 1% of the planet's size. At a depth of 3,300 ft, the pressure reaches 330 atmospheres. That's like four elephants piled up on your head or two pandas balanced on your thumbnail.

    About 6,500 ft below the surface, you still can meet some living creatures! Those are springtails - teeny eyeless insects that live in super-deep Krubera Cave. The deepest multicellular animal people know about lives at a depth of 11,800 ft in the TauTona mine in South Africa. This may sound strange, but a lot of interesting things happen underground. For example, 510 ft underground, you find the world's deepest hotel, and in 2020, the world's deepest concert took place at a depth of 6,200 ft!

  • What Would a Journey to the Earth’s Core Be Like?

    9:57

    ???? Brighten your style with our MERCH (open globally!) here:

    What’s the most exotic destination you’ve been to? Hawaii? Australia, Hoboken, New Jersey? Well, today I’m setting off on a journey that’s way more unusual than that – down to the Earth’s core. And I’m inviting you to join me. It’ll be fun! The center of the Earth lies about 4,000 miles below its surface, so it’s gonna be a looong trip.

    ???? By the way, guys, be attentive! To make the journey even more fascinating, I've hidden something interesting in this video. Okay, I'll give you a hint - it's movie references! You definitely saw them because each of those films is iconic. Try to find them all and let everyone know you have a sharp eye in the comments! If you're a video game fan, there's a reference for you too. But this one is really difficult.

    ???? And, of course, there is a cat hidden in this video. Can you spot it? C'mon, prove you're much more attentive than most people! Do you accept the challenge? ????

    #earth #geology #brightside

    SUMMARY:
    - The crust isn't really that thick. It’s roughly 21 miles thick and is made up of basaltic rocks that are under the sea, and granitic rocks that make up the continents.
    - Nile Crocodiles dig the deepest burrows among all animals, so you can find them at 39 feet under ground.
    - There are whole underground cities with shelters and catacombs in different countries. The deepest of them lies at 278 feet under Cappadocia in Turkey.
    - Continental crust is about 2 billion years old and it covers about 40 percent of the Earth (yeah, the rest is oceanic crust).
    - In 2004, a half-marathon was organized in the Bochnia Salt Mine in Poland. It was the deepest half-marathon ever – you don’t often see people running at a depth of 695 feet after all.
    - The Earth’s crust serves as an electric blanket that covers the mantle. It’s rich in the radioactive elements uranium, thorium, and potassium, which produce heat!
    - The oceanic crust is never too far, and its average depth is 4.3 miles. It covers around 60 percent of the surface of our planet, and is thinner, denser and younger than the continental crust.
    - The pressure is getting more and more extreme, and it’s getting colder and colder down here. This is the deepest point where earthquakes are born – the ones that come from here are rare, and get pretty weak by the time they’ve traveled 435 miles up to the surface.
    - At 1,814 miles deep, the mantle ends and the outer core begins. It’s a sunless sea of super hot liquid metal that’s about the size of Mars.
    - Once every several thousand years, something happens in this layer: the magnetic poles reverse, and north and south change places.
    - At 2,750 miles, the inner core welcomes you! It’s the hottest, innermost part of the planet.
    - The inner core is nearly the size of the Moon, and makes up 2 per cent of the Earth’s mass.
    - Not so long ago, British scientists found out that the inner core is relatively young – probably somewhere between 500 and 1,000 million years old, and that’s nothing in terms of Earth science.
    - Now, for those of you who are thinking of packing your bags to go see the Earth’s core, I have some not-so-good news: it’s technically not possible yet, because there’s no way to survive the pressure and extreme heat that are waiting down there.

    SUMMARY:
    - At a depth of 2.3 ft, you'll find numerous mole tunnels and rabbit warrens. By the way, a mole can dig a tunnel longer than 65 ft in just one day!
    - Deep-burrowing species of earthworms can be spotted at a depth of 10 ft. One of them, Drawida grandis, can grow up to 3.5 ft long.
    - You can still find the roots of tropical forest plants if you dig 23 ft down. Tropical trees need such long roots to store water during dry periods.
    - When we arrive at a depth of 60 ft, we can see Beijing's Underground City. That's a subterranean bomb shelter consisting of a vast network of tunnels and underground rooms. It’s situated under the capital of China.
    - In Cappadocia, Turkey, there's an underground complex that probably dates back to the 7th century. Its name is Derinkuyu Underground City, and it's situated almost 280 ft below Earth’s surface.
    - The Channel Tunnel, connecting the UK with France, is situated at a depth of 377 ft.
    - The deepest railway tunnel is located at a depth of 787 ft. That's the maximum depth of the Seikan Tunnel in Japan that opened in 1988.
    - Even if we could get down to 1,001 ft, we’d still be in the danger zone for a B82 Earth-penetrating nuclear warhead. That's its maximum destructive depth.
    - At a depth of 3,800 ft, there's the deepest bat colony in the world. About 1,000 brown bats spend every winter in a zinc mine in New York.
    - About 5,920 ft down and we arrive at the deepest part of the 227-mile-long Grand Canyon. Its average depth is 5,282 ft.
    - The average depth of the oceanic crust is almost 20,000 ft. This is also the depth of the deepest known microbes. They were found in rocks below China's Songliao Basin.
    -The winner in the category of the deepest artificial hole on Earth is Z44-Chayvo Oil and Gas Well. This shaft is drilled down to a whopping 40,604 ft! That's 15 Burj Khalifas put on top of each other. The shaft is located in the Russian Far East.

  • Why the Earths Core Is Hotter Than the Sun

    8:52

    We’ve managed to go hundreds of thousands of miles into space, but when it comes to the earth, we’ve barely scratched the surface. Our planet’s core is a magnificent mystery filled with secrets. It’s time to figure them out.

    The Earth’s inner core is an extra hot solid ball that has a radius just 30% smaller than the Moon. Scientists figured out that most of the Earth’s mass is located towards the center of our planet. The temperature of the inner core is about 9800°F. While the melting point of pure iron is about 2,800°F, at the core, its melting point is around 11,000° F.

    Why is the earth still boiling? 5:50
    A 2015 study from Durham University 6:53

    #earthcore #earthfacts #brightside

    SUMMARY:
    -It’s estimated that the Earth’s mass is 5.6 sextillion tons. More than 80% of the core consists of one of the ten most common elements in our galaxy: iron.
    -In 2013, Wendy Mao and her team from Stanford discovered a possible solution for how this happened. During their experiment, molten iron slowly squeezed through the silicate rocks, and they had their answer. It took millions of years for the iron to reach the center, so it happened at a snail’s pace.
    -During an earthquake, shockwaves are spread through the planet. Seismologists study these vibrations and try to read the reflections on the other side. As science progressed, it turned out that picky “S-WAVES” could only go through solid material, and not liquid. So something molten was present in the center of the Earth that was preventing the vibrations from going through.
    -The temperature of the inner core is about 9800°F. While the melting point of pure iron is about 2,800°F, at the core, its melting point is around 11,000° F. The fluctuation in those temperatures comes from factoring in the extreme pressure the iron is exposed to at the core.
    -The reason it remains solid is because of the slow cooling of the outer core and its compression. The inner core spins faster than the Earth. That’s caused by the thermal activity inside our planet which creates the magnetosphere.
    -The first reason the Earth is still boiling is that the core has remained hot from the time our planet was formed – roughly 4.5 billion years ago. Secondly, it generates heat from the friction of the dense materials as they move. And the last reason it’s so hot is from the decay of radioactive elements.
    -A 2015 study from Durham University claimed that 90% of the Earth’s sulfur is in the core. When the impact happened, the Earth’s mantle melted, and some sulfur-rich liquid squeezed through the ruins and reformed it. Some of it was probably lost in space, but the rest sunk to the core.

    Will the magnetic field of the Earth reverse its direction in the future? Will this cause problems?

    The magnetic field of the Earth has actually switched its direction many many times during Earth's history. Although this is not completely understood, the leading theory of how it works is that Earth's magnetic field is caused by the motion of the liquid outer core. The churning of the liquid in the outer core acts as a giant electromagnet, moving electrical charges around, in what is known as the 'geomagnetic dynamo.'

    Every other Wednesday we present a new video, so join us to see the truth laid bare...

    There is a place on Earth that we have never seen. It is a place of unimaginable heat and pressure, where no life could survive. Yet without it, we would perish for it holds the key to our precarious existence on this planet.

    2000 miles below the Earth's surface, there is a vast ocean of molten iron. The spinning outer core of the Earth generates a protective magnetic shield around the planet, defending life from lethal space radiation. But now there is startling data that it could be about to stop defending us. Naked Science is taking you on a journey to the centre of the Earth.

  • What If Earths Core Turned to Ice

    8:23

    Imagine there’s a huge hot ball hidden inside the Earth. It's floating in an ocean of molten metal. This ball also spins on its axis, but it moves faster than the rest of our planet. This is what the Earth's core looks like. The solid metal ball is the inner core, and it’s 750 miles thick. The outer core is the molten ocean. To reach the edge of it, you would need to dig a tunnel into the Earth that was about 3,700 miles long.

    But you would hardly want to go there, because it’s the hottest point on the planet. The core temperature is 11,000 degrees Fahrenheit. Humans have learned to use the heat coming from inside the Earth as a source of energy. If the core ever cooled down and that heat disappeared, this kind of electricity might become very expensive. Phones, computers, the Internet – all these things would cost a lot more. But this would actually be the least of our worries... So what would happen if the Earth's core went cold?

    Also, earthquakes occur when tectonic plates rub against each other. These plates move because of the intense heat coming from the core. Now, no heat from the core means no movement of tectonic plates, thus no earthquakes.
    Scientists believe that earth's heated core plays an important role in the creation of its magnetic field. With no magnetic field, the following things will occur.
    Our atmosphere will slowly but surely disappear as there will be no protection from harmful solar winds.
    Also, migratory birds would have a very hard time finding their destination.

  • What Would a Journey to the Earth’s Core Be Like?

    11:01

    What’s the most exotic destination you’ve been to? Hawaii? Australia, Hoboken, New Jersey? Well, today I’m setting off on a journey that’s way more unusual than that – down to the Earth’s core. And I’m inviting you to join me. It’ll be fun! The center of the Earth lies about 4,000 miles below its surface, so it’s gonna be a long trip.

    ???? By the way, guys, be attentive! To make the journey even more fascinating, I've hidden something interesting in this video. Okay, I'll give you a hint - it's movie references! You definitely saw them because each of those films is iconic. Try to find them all and let everyone know you have a sharp eye in the comments! If you're a video game fan, there's a reference for you too. But this one is really difficult.

    #earth #geology #history #brightside

    SUMMARY:
    - The crust isn't really that thick. It’s roughly 21 miles thick and is made up of basaltic rocks that are under the sea, and granitic rocks that make up the continents.
    - Nile Crocodiles dig the deepest burrows among all animals, so you can find them at 39 feet under ground.
    - There are whole underground cities with shelters and catacombs in different countries. The deepest of them lies at 278 feet under Cappadocia in Turkey.
    - Continental crust is about 2 billion years old and it covers about 40 percent of the Earth (yeah, the rest is oceanic crust).
    - In 2004, a half-marathon was organized in the Bochnia Salt Mine in Poland. It was the deepest half-marathon ever – you don’t often see people running at a depth of 695 feet after all.
    - The Earth’s crust serves as an electric blanket that covers the mantle. It’s rich in the radioactive elements uranium, thorium, and potassium, which produce heat!
    - The oceanic crust is never too far, and its average depth is 4.3 miles. It covers around 60 percent of the surface of our planet, and is thinner, denser and younger than the continental crust.
    - The pressure is getting more and more extreme, and it’s getting colder and colder down here. This is the deepest point where earthquakes are born – the ones that come from here are rare, and get pretty weak by the time they’ve traveled 435 miles up to the surface.
    - At 1,814 miles deep, the mantle ends and the outer core begins. It’s a sunless sea of super hot liquid metal that’s about the size of Mars.
    - Once every several thousand years, something happens in this layer: the magnetic poles reverse, and north and south change places.
    - At 2,750 miles, the inner core welcomes you! It’s the hottest, innermost part of the planet.
    - The inner core is nearly the size of the Moon, and makes up 2 per cent of the Earth’s mass.
    - Not so long ago, British scientists found out that the inner core is relatively young – probably somewhere between 500 and 1,000 million years old, and that’s nothing in terms of Earth science.
    - Now, for those of you who are thinking of packing your bags to go see the Earth’s core, I have some not-so-good news: it’s technically not possible yet, because there’s no way to survive the pressure and extreme heat that are waiting down there.

  • Earths Core Is Actually Hotter Than the Sun!

    13:23

    Earth's core:From what the core of the Earth is really made of, to what its temperature could mean for the planet itself, join as we explore whether the Earth's Core Is Actually Hotter Than the Sun.

    I want you to picture the Earth right now. You can picture it as if you're looking outside your window, or as if you're in space looking at the Earth in its entirety. On this planet, of which we are the only one that we know of that has life, we have done many wondrous things. And over the course of many thousands of years we have learned many amazing things about our planet.
    We've learned how it works for the most part, we've learned how planets grow and allow creatures like us to breathe via things like Photosynthesis, we learned about the history of the world and some of the many creatures that lived in it before humanity ever got there.
    And to be clear, we obviously haven't learned EVERYTHING that this world has to offer, there are many mysteries that still lie out there waiting for us to solve them. But one of the biggest mysteries by far is that of the core of the earth.
    While it's true that we THINK we know what's at the Earth's core...we honestly don't know the truth of it for a very simple reason...we can't reach it. The average distance to the Earth's core is just about 4000 miles beneath the ground that you stand on. Which may not seem like a lot when we've gone into space and have a probe that's gone well past Pluto (which is still a planet...) but the difference between space and the core of our planet is pressure and heat. The deeper we go into the planet, the more pressure that is exerted (not unlike the ocean where the deeper you go the more protection you need) and the hotter that you get.
    At present, we have been unable to drill to the core, in fact, we haven't even gotten close! The closest drill hole that has been dug via the actual surface of the Earth (this does not include the ocean) is about 7.5 miles via the Kola Superdeep Borehole that was dug by the Soviet Union. Why did they get stopped? Because at that point in their drilling...every single drill bit that they tried to use to get deeper...melted.
    Told you it's hot down there. And yeah, it's REALLY hot. But what has surprised people in many years is that the temperature of the core might just be hotter than you expect, including being hotter than the surface of the sun.
    The earliest guesses (based on science and backed up by actual samples of items from within the Earth like the ones taken by the Kola Superdeep Borehole) of the Earths' core temperature came in the 1900's. They looked at samples of iron within the Earth and did tests on the iron to suggest that the core of the Earth was around 5000 degrees Celsius.
    It was just the beginning of these kinds of measurements so they made a first estimate... to constrain the temperature inside the Earth, said Agnes Dewaele of the French research agency CEA and a co-author of the new research.
    But...
    Other people made other measurements and calculations with computers and nothing was in agreement. It was not good for our field that we didn't agree with each other,
    Obviously debate doesn't lead to definitiveness. But you might be curious as to why the core temperature of the Earth matters. I mean, clearly it's hot enough to keep the Earth going (more on that later) and obviously since the planet has been around for potentially billions of years we don't have to worry about it erupting, right? And yeah, you are, but you're thinking about this in a much smaller scale.
    There are many disciplines of science that rely on accurate data, and having the correct temperature of the Earth is a welcome thing to have for those trying to study all aspects of the Earth:
    We have to give answers to geophysicists, seismologists, geodynamicists - they need some data to feed their computer models, Dr Dewaele said.
    Without the right data, the more errors and guesses and estimates have to be made, and as time goes on, that makes science more theoretical than proven. And thus, the push to find the true temperature of the Earth continued.
    Based on our best guesses, the Earth's core is a solid ball of iron and possibly nickel. This is why tests on these metals are at the forefront of trying to figure out the temperature. And after a while, scientists figured out a new way of looking at iron samples to try and determine how hot the core was, and they did it using something that's been around for decades...X-Rays.
    How did they do this? By making use of the European Synchrotron Radiation Facility - one of the world's most intense sources of X-rays.

  • A New State of Water Reveals a Hidden Ocean in Earth’s Mantle

    4:07

    Diamonds from deep within the earth carry a new form of water ice, Ice-VII, that confirms there’s an ocean underneath us! Here’s what we know.

    This Massive Asteroid Is Headed for Earth…. What Now?-

    The Hunt for Earth’s Deep Hidden Oceans
    “These mineral flecks — some too small to see even under a microscope — offer a peek into Earth’s otherwise unreachable interior. In 2014, researchers glimpsed something embedded in these minerals that, if not for its deep origins, would’ve been unremarkable: water.”

    Ice-VII inclusions in diamonds: Evidence for aqueous fluid in Earth’s deep mantle

    “Small inclusions in diamonds brought up from the mantle provide valuable clues to the mineralogy and chemistry of parts of Earth that we cannot otherwise sample. Tschauner et al.found inclusions of the high-pressure form of water called ice-VII in diamonds sourced from between 410 and 660 km depth, the part of the mantle known as the transition zone. The transition zone is a region where the stable minerals have high water storage capacity. “


    The Earth’s Hidden Ocean

    “Dr. Jacobsen synthesizes deep-earth minerals by replicating the extreme pressures that exist hundreds of miles below the surface. Over the years when he has made a blue mineral called ringwoodite, which is ubiquitous in the transition zone, it has formed with water. But that was just lab work, Dr. Jacobsen said, adding, “We haven’t known whether it could happen down there.”

  • Scientists Detect Signs of a Hidden Structure Inside Earths Core

    3:16

    The presence of an innermost layer has been suspected for some time now, with hints that iron crystals which compose the inner core have different structural alignments.

    We are limited by the distribution of global earthquakes and receivers, especially at polar antipodes, the team wrote in their paper, explaining the missing data decreases the certainty of their conclusions. But their conclusions align with other recent studies on the anisotropy of the innermost inner core.

    A new method currently under development may soon fill in some of these data gaps and allow scientists to corroborate or contradict their findings and hopefully translate more stories written within this early layer of Earth's history.

    This research was published in the Journal of Geophysical Research.

  • We Still Don’t Know What’s Inside Earth’s Core—Diamond Anvils May Be the Answer

    4:44

    We’ve never been able to journey to the center of the Earth, but thanks to an incredibly innovative experiment, we may not have to go there to understand what it's like.

    Historically, we’ve explored our planet's interior using seismic measurements—basically, measuring vibrations that pass through the Earth to tell us more about what’s going on in there. Thanks to research like this we know the Earth has an innermost, super dense solid core, surrounded by a less dense, liquid outer core

    But now, an exciting new experiment tells us details about the Earth’s core that we’ve never had access to before by using something called a diamond anvil cell, two diamonds pressed together to create a tremendous amount of pressure, to achieve its results.

    By putting a sample of a material in a diamond anvil cell we can see how it behaves under these extreme pressures, which is exactly what these researchers did with liquid iron. Iron is not only the 6th most abundant element in the universe, it’s also thought to make up a large part of the core of our own planet, and the cores of Mercury and Mars.

    Find out how this new breakthrough could help us get a better picture of the way Earth’s interior has evolved in this Elements.

    Why is the earth's core so hot? And how do scientists measure its temperature?

    Iron is the only element that closely matches the seismic properties of the earth's core and is also sufficiently abundant present in sufficient abundance in the universe to make up the approximately 35 percent of the mass of the planet present in the core.

    Earth's inner core is doing something weird

    Better understanding the history and current dynamics of the iron blob nestled within our planet could yield more clues to the processes charging and stabilizing our magnetic field—a geologic force field that protects our world from various kinds of harmful radiation.

    This mysterious new ecosystem is being called the ‘subterranean Galápagos’ and it’s almost twice the size of Earth’s oceans. We’ve never seen anything like it.

    Life in Deep Earth Totals 15 to 23 Billion Tonnes of Carbon—Hundreds of Times More than Humans

    “The absolute limits of life on Earth in terms of temperature, pressure, and energy availability have yet to be found. The records continually get broken. A frontrunner for Earth’s hottest organism in the natural world is Geogemma barossii, a single-celled organism thriving in hydrothermal vents on the seafloor. Its cells, tiny microscopic spheres, grow and replicate at 121 degrees Celsius (21 degrees hotter than the boiling point of water)”

    Weird Organisms Emerge From The Deep, Dark Biosphere

    “The analysis has revealed some known microbes and many completely unstudied ones. Many of these mystery microbes are very small cells, with small genomes laced with unfamiliar genes. “Fifty per cent of the genes in these genomes have no known function,” says Banfield – an unusually high proportion.”

    The Biomass And Biodiversity Of The Continental Subsurface

    “Using our updated continental subsurface cellular estimate and existing literature, we estimate that the total global prokaryotic biomass is approximately 23 to 31 Pg of carbon C (PgC), roughly 4 to 10 times less than previous estimates.”
