How Hot is the Centre of the Earth? | My Amazing Earth | BBC Earth Science

Did you know that the Earth's core is as hot as the surface of the sun? But why? And how do we even know this?

Knowing all these it seems like someone carefully designed it. How can we not believe in God?

Because it would demand moral accountability, they don’t want that. It isn’t the lack of evidence, it’s The denial of “ Sin” Romans address’s the issues

[@Grabthar191]

So what would it take to make a vehicle like the one in the movie "The Core", or build a transport through the earth like in the remake of "Total Recall"? I suppose they'd have to find some fictional element like "unobtanium" or like Wolverine's "Adamantine".

It's also why Japan can have their beautiful bath houses fill up with piping hot minieral-rich water basically for free.

Why not understand our planet first before thinking of reaching other planets. We literally know nothing about our planet and we are thinking of mars. Astonishing

Can you explain why we aren't using geothermal energy globally?

[@tjp2009]

I'm guessing it would be expensive and use a lot of materials

[@frosted1030]

@@tjp2009 Geothermal is already powering countries. It's less expensive and safer than nuclear, and more renewable. Works all the time, unlike wind solar and wave power. Kinda stupid not to use this.

[@huldu]

If you had a small planet or a moon next to a gas giant such as saturn or jupiter would it "protect" it from the solar radiation - assuming the gas giant was close enough? Even if the gas giant was very far away like ours are could life possibly exist near one(in orbit) if it's covered by a thick atmosphere or an ice sheet? Would the heat generated from the core be enough to create liquid water? There appears to be some evidence of this on some moons in our own solar system. I hope one day humans explore and figure out what's going on.

To bad iron looses magnetic properties at 1500°f.... explain that??? This is just a theory at the end of the day

[@th3d3wd3r]

Did you listen to her? Did she say it's a giant bar magnet with fixed magnetic domains? No, she didn't, yet that's the model you're arguing against

[@Me11owDome]

@@th3d3wd3r wrong.... and that has nothing to do with the fact that anything beyond 8 miles down is pseudoscience. How can you get all that data from just looking at seismic activity? The curie point States that iron loses magnetic properties at 1500ﾟ but they tell us that the Earth core is at 10000ﾟ??? Makes no sense.

[@tumbleddry2887]

kzbin.info/www/bejne/qHK8iGykbc5geZY Start here....then move on to any chemistry/physics/seismology/geology vids you can get you can to learn some basics. You'll start to have a better understanding of how/why these physical phenomena are known. You also might want to get a better understanding of what is meant by "theory", "hypothesis" and "conjecture" in mathematics and the sciences. It could take you awhile given your comments but you can do it.

[@thany3]

Magnets don't work they way you expect them to, when heated well past everything's melting point and at millions of times atmospheric pressure. In a similar way, magnets also don't work the way you expect them to, if you don't know what they do a near absolute zero. Then too, they stop making sense.

[@GraveUypo]

answer the question! how hot IS the surface of earth if you don't account for the heat it receives from the sun?

[@huldu]

Apparently some moons near our gas giants have liquid water underneath their massive ice sheets. Would that mean that the heat generated from the core is enough or is the gas giant helping creating the heat? Since they're so far away from the sun it barely has any effect on the heating, right?

[@GraveUypo]

@@huldu just a few kilometers down and temperatures go above boiling, stands to reason that the surface still gets some heat from the core. i wanted to know how much that was when i clicked the video. i would think earths surface would be above 100 kelvin with no sun.

[@brightax7502]

and climate change lol

[@BioTechproject27]

@@huldu yes they get some heat from their gas giants through the gravitational forces. Since they don't have perfectly circular orbits they get stretched and compressed, which generates heat. and yes, the suns energy is pretty negligible there.

Yes, but how do we know the surface of the sun is 6000c too? Did we send a man up a long ladder with a thermometer on a big stick

[@phur3i0n]

The color of light a star emits is related to its temperature. This means that we can determine the effective temperature of the Sun by measuring the amount of light it emits at each wavelength and comparing the resulting spectrum we see to model

[@Sannidor]

That's nonsense. We just don't know.

[@phur3i0n]

But we have theories.... Which give a good idea of what could be happening. What's your theory? God?

[@thany3]

Those are two independent unrelated statements. We don't know for 100% sure. But that doesn't mean it's utter bollocks. This is just how science works, mate.

[@brightax7502]

you don’t know but other people do know because they research

[@Sannidor]

@@brightax7502 Not really, no. They assume, guess, speculate. It's not "research" and it's not a scientific process.

Unprovable pseudoscience

[@Hokunin]

I thought video just proved it to you. Where do you think hot lava is coming from? And why earthquakes happen?

[@Me11owDome]

@@Hokunin that has nothing to do with the fact that anything beyond 8 miles down is pseudoscience. How can you get all that data from just looking at seismic activity?

[@BioTechproject27]

@@Me11owDome u can get data from seismic activity because the shockwaves they send get refracted and reflected differently, depending on the materials shape, temperature, density, etc. when whe know where the origin of the wave was and we have multiple stations across the world to measure delay and intensity, we can create a 3d map with the help of computers. And your argument about the curie point doesn't matter as shown in your other comment.

[@Me11owDome]

@@BioTechproject27 so you can get the temp and the type of material 1000s of miles deep into the earth just from looking at the seismic activity? The data doesn't prove anything. And why doesn't the curie point matter? That's something we can demonstrate everyday, its a fact! So that doesn't apply here???

[@phur3i0n]

So what's your probable scientific explanation?
