Nation World News, kilat.com – soA new study published in Nature Communications suggests that life on Earth was possible only because of a “rejuvenation” of the planet’s core. The study also noted that about 565 million years ago, Earth’s magnetic field had dropped to about ten percent of its current strength and the planet was on its way to the same fate. Mars planet Where life has not yet been found.
This magnetic field is supported by a phenomenon called the Cambrian Explosion or “Biological Big Bang”.
“The inner core is very important. Just before the inner core grows, the magnetic field is at the point of collapse, but as the inner core begins to grow, the field regenerates,” said John Tarduno, the paper’s correspondent author, in a press statement. Told. ,
The study takes into account rocks near Earth’s center, tested with the help of a carbon dioxide laser and a superconducting quantum interference device (SQUID) magnetometer. The goal is to detect key changes Earth From time to time.
According to research, rocks in the outer core of Earth’s surface show that electric currents generated by the present magma generate a magnetic field that gains strength.
Turns out, it turns out that this is where Mr. Mulyani’s location saves the state money?
“Since we demarcated the age of the inner core more accurately, we were able to infer the fact that the present inner core actually consists of two parts. The movement of tectonic plates on Earth’s surface indirectly affects the inner core. impacts the core, and the history of this movement is deeply inscribed within the Earth in the structure of the inner core,” Tarduno said in his press statement.
