Discovered 'green witch' - what makes Earth have life

Earth was once a terrifying ball of fire with a deadly atmosphere full of deadly carbon dioxide. But a mystery arose, turned the earth clean and hid deep underground for billions of years.

As the evidence shows, just as the name of the first geologic time - Hadean, ie the Great Fire City - Earth was once a hard-to-live fireball, the sky covered with carbon dioxide clouds like Venus, according to Sci-Tech Daily.

But then it changed spectacularly and became more and more breathable and cooler. In addition to the planet's natural cooling, geological evidence suggests that the Earth has undergone a strange makeover in which deadly carbon dioxide is rapidly consumed.

Earth has ended the "hell fireball" stage with the help of mysterious "green witch" rocks

Two geologists Jun Korenaga and Yoshinori Miyazaki from Yale University (USA) combined aspects of thermodynamics, fluid mechanics and atmospheric physics to reconstruct a model of the Earth and come to a conclusion. that the early earth was covered with a rock that no longer exists.

These are rocks that are rich in a mineral called pyroxene, which can have a beautiful green color, extremely rich in magnesium.

These magnesium-rich minerals reacted strongly with carbon dioxide to produce carbonates, which play an important role in sequestering carbon in the atmosphere.

As the molten Earth began to solidify, its warm and hydrated mantle - the planet's 3,000 km thick rock layer - also underwent a dramatic transition, combined with carbon-repulsive "green witch" rocks. hateful diodixe in just 160 million years.

"As an added bonus, these exotic rocks would readily react with seawater to produce a large influx of hydrogen, which is necessary for the creation of biomolecules," added Professor Korenaga.

After that magical period, this mysterious green rock that followed Earth's complex plate tectonics sank deep into the mantle, ending its mission.

The study has just been published in Nature.
