How does this affect us?
These changes in the Earth’s core have the effect of changing the people living on the planet’s surface in terms of navigation and even the length of the day. This is due to the phenomenon called magnetic field. Our planet revolves around itself in space. The metal core of the Earth also rotates in the same way. These movements create the magnetic force that surrounds the Earth, called the magnetic field.
The north and south poles of the Earth, which we can consider as a giant magnet, are like magnetic poles. But somewhat confusingly, the geographic north and south poles and the magnetic poles are not exactly in the same place, and they are also on the move. The north magnetic pole has shifted 1,400 miles north of Canada to Siberia in Russia since it was discovered in 1832.
The movement of the north magnetic pole has accelerated so much in recent years that changes have to be made to the navigation devices used in military and commercial transportation and search and rescue operations operating around the North Pole.
Earth’s magnetic field is also responsible for controlling how fast or equally slow the earth rotates on its axis, in other words how long our days are. Just as with the quarterly leap year, even a slight slowdown in the rotation that creates a day has resulted in the need to add 27 leap seconds since the 1970s to keep the time accurate.
The rate at which the Earth spins on its axis is believed to have changed continuously throughout history due to variation in the rotation of the inner core. But not all scientists agree with these new findings.
A well-known geophysicist in America, Dr. John Vidaleis skeptical of the results announced by Chinese scientists. Vidale likens our view of the earth’s core to an observation without a scanner, and “Our view of the Earth’s interior is still blurred” says.
screw, “Something’s going on and I think we’ll be able to figure it out, but it may take ten years.” he adds.
