New discovery of the heat of Earth's core coating

According to the latest study, the Earth's core coating is as hot as 1,410 degrees Celsius, which is 60 degrees C hotter than our previous understanding.

The discovery shows that the Earth's core coating, also known as Mantle , is about 60 degrees C hotter than what scientists previously knew.

This finding will help scientists more accurately simulate Earth's geodynamic processes, including tectonic plate activity. The temperature difference is not large, but its effect is very large.

"If the core of the Earth's core is hotter, which means it will melt more easily. This leads to a tectonic plate above the soft pad that can glide more smoothly," said researcher Emily Sarafian at The Department of Geology and Geophysics at the Massachusetts Institute of Technology, who led the research team, said.

"If you put the honey jar in the refrigerator for an hour, it will hardly melt after you take it out. But if you put it on a hot stove, of course it will melt right away. This is also regarding the warming of Mantle, " Sarafian added.

Of course scientists do not actually touch this coating to measure the temperature, but rely on volcanic activities on the ground, then analyze them in the laboratory through simulated simulations.

When conducting the simulation, the researchers found that water exists in the coating, although very little. This shows that the coating is not completely dry by hot fire, but it still has liquid water.

However, there is no specific determination of the amount of water existing in the coating. The amount of water here is very important, contributing to cooling or heating up the temperature of the coating below.

Finally, scientists simulate with the most accurate amount of water. And the final result shows that the mantle volume that is closer to the Earth's surface will melt more , which goes against previous studies, suggesting that the mantle will melt more when lying deeper.

"Previous studies have incorrectly assessed the temperature of the Earth's core coating. In fact, this coating is 60 degrees C hotter than previous studies, a significant difference in temperature , " said Sarafian. added.

"This discovery will change geophysical explanations and observations of the world in the future," said Geology and Geochemistry professor Paul Asimow, who is studying at the California Institute of Technology, said. my opinion.
