The formation and evolution of our planet is still a big mystery. If the planet were 100 years old today, we could say that humans He was born just a month ago. That’s all, 6 million years for humans compared to 4,500 million years for Earth.
so true We can only imagine and guess about such a long history that we have not seen. What was the planet like a billion years ago? We’ll never know. But still, from time to time science find amazing things About Earth’s past.
research done in Curtin University and published in Nature he got a proof heavy that who created the continents on planet earth, astonishingly, giant meteor impact in the first billion years of his life.
have you stopped to think that the earth is only known planetsBetween the Solar System and the Outer, where are the continents, And since continents are home to most of Earth’s biomass, nearly every major mineral deposit on the planet, and of course they are home to humans, Understanding their background can also be key to understanding them. evolution of our own species,
Tim Johnson, School Researcher of earth and planetary science De Curtin noted that the idea that continents were originally formed at giant meteorite impact sites has been for decadesbut what was there little proof To support the theory, so far.
How did scientists discover that giant meteors may have formed Earth’s continents?
Researchers analyzed small zircon crystals In rocks found in the Pilbara Craton of Australia. these are crystals Unique Ancient Archaic Crust are identified on the planet, that is, the living remains of the planet that was approx. 4 billion years.
study revealed melting process that started at the surface and then progressed to the bottomAnd not the other way around, which is consistent with a geologic effect caused by the impact of giant meteorites.
Our research provides the first strong evidence that the processes that resulted in the formation of continents were triggered by a massive meteorite impact similar to the one that caused the extinction of the dinosaurs only billions of years ago. Tim Johnson.
Now that we know that new climate change mitigation technologies require products that are extracted directly from the Earth’s crust, such as Lithium, Tin and NickelWith the urgent need it is necessary to understand how the continents were formed and what happened to the process called cortex differentiation,
Earth’s core oscillates and changes the length of days!
Scientists plan to test the findings other regions of ancient continental crust around the planet, To find out if the model is really universal. For now, we can only imagine their great influence. When these meteors hit our planet and formed its surface, one wonders how much remains to be discovered.
