Scientists Find Earth’s Core Cooling Faster Than Expected, What’s Going On? – After world

KONTAN.CO.ID – JAKARTA. Scientists found that the process of cooling the planet’s core is happening faster than previously thought.

The core of planet Earth has indeed been cooling over billions of years, but the cooling process is now recorded to be accelerating, consequently hastening the end of life on Earth.

The researchers found that the Earth’s interior has gradually cooled over the 4.5 billion years of its existence.

These cooling conditions are thought to be a common pattern that may have helped the planet evolve into the green paradise it is today, where humans have thrived for the past 200,000 years.

“This perspective raises the question of how quickly the Earth has lost heat throughout Earth’s history, which directly relates to the fundamental question of how long the Earth will remain dynamically active,” the scientists write in an article published in the journal Earth. NBCNews.

So far, researchers are still researching how fast the cooling process of the Earth’s core is. A group of scientists are studying bridgmanite, a common conductive mineral between the Earth’s core and mantle.

They found that it was 1.5 times more conductive than previously thought, meaning the Earth’s cooling process could also be faster than previously thought.

“We found that the thermal conductivity at the core-mantle interface is 1.5 times higher than the conventionally assumed value, favoring higher heat flux from the core, resulting in stronger than expected mantle convection,” the researchers added added.

“The results indicate that the mantle was being cooled more efficiently, which would ultimately dampen much of the tectonic activity driven by mantle convection faster than would be expected from conventionally assumed thermal conduction behavior.”

As the planet cools, it loses its magnetic field, which protects Earth from harmful cosmic rays. At that time the earth will be a sterile and uninhabitable rock.

Researchers do not estimate how many more years life could exist on Earth.

A 2013 projection by Andrew Rushby of the University of East Anglia in the UK puts Earth’s survival as good for another 1.75 billion to 3.25 billion years, assuming there are no nuclear catastrophes, rogue asteroids or otherwise unforeseen disasters.
