A massive iron sphere that sits at the centre of the Earth is gradually expanding. This is the inner core, and exciting new data reveals that the creation of this region half a billion years ago may have had a significant impact on the development of life on Earth. They contend that during the time, our Planet’s magnetic field was deteriorating, which may have had serious effects. This field often shields life on Earth from cosmic radiation and charged particles that are generated by our sun.
However, 550 million years ago, it was only a small portion of its current strength before it suddenly recovered it. And as a result of this Planet’s reset, sophisticated multicellular life suddenly began to proliferate across Earth’s surface. The majority of the main animal groupings first emerged in the fossil record during the Cambrian boom. Now, scientists have connected it to occurrences right in the centre of the Planet’s.
According to John Tarduno, a geophysics professor at the University of Rochester in New York, the outer core of the Planet’s produces the spinning iron that creates the magnetic field of the Planet’s. The core was completely molten and losing its capacity to produce a magnetic field prior to the Cambrian explosion.
