Researchers at ETH Zurich have demonstrated in the lab how well a mineral common at the boundary between the Earth’s core and mantle conducts heat. This leads them to suspect that the Earth’s heat may dissipate sooner than previously thought.
The evolution of our Earth is the story of its cooling: 4.5 billion years ago, extreme temperatures prevailed on the surface of the young Earth, and it was covered by a deep ocean of magma. Over millions of years, the planet’s surface cooled to form a brittle crust. However, the enormous thermal energy emanating from the Earth’s interior set dynamic processes in motion, such as mantle convection, plate tectonics, and volcanism.
Still unanswered, though, are the questions of how fast the Earth cooled and how long it might take for this ongoing cooling to bring the aforementioned heat-driven processes to a halt.
One possible answer may lie in the thermal conductivity of the minerals that form the boundary between the Earth’s core and mantle.
This boundary layer is relevant because it is here that the viscous rock of the Earth’s mantle is in direct contact with the hot iron-nickel melt of the planet’s outer core. The temperature gradient between the two layers is very steep, so there is potentially a lot of heat flowing here. The boundary layer is formed mainly of the mineral bridgmanite. However, researchers have a hard time estimating how much heat this mineral conducts from the Earth’s core to the mantle because experimental verification is very difficult.

No, it wasn’t covered in a deep ocean of magma. In my Bible, it says it was covered with water and the Spirit moved over it. Uhhh, and that was about 6,000 years ago, not 4.5 billion. These fools cannot tell you what the weather will be next week, even two days from now, but they can tell us that we are all going to die from climate change in 100 years if we don’t quit using gas cars, having fires outside, using oil and gas, and git rid of all the cows because they are farting away the atmosphere??? Give me a freaking break. These idiots just DREAM IT UP and say it and everyone believes it. No proof. Just like all liberals, just say it and it is proof. BS.
It’s that geo-thermal Bitcoin mining in El Salvador, sucking the heat right out of our precious Mother Earth to mine filthy lucre.
Now we’ll all freeze in 3 billion years.
I knew this would happen, damn you Satoshi.

It’s from a land down under.😏
>>> That “dust” blocks sunlight which causes the Earth’s surface to cool.
lol... well, God says it’s about to get VERY warm.

Will more taxes help stop this?
How much toilet paper are we going to need for this? 🤔
Q: Is there anything we can do about it?
A: No
Just for fun, some reporter should ask Kamala Harris for her opinion on this.
