Monday, Nature Geoscience, has been reported that the Earth’s Inner Core has stopped rotating. How it will affect our lives, it’s still not revealed.
Earth’s Inner Core No Longer Rotating
We don’t feel the rotation and inner activities happening at the earth’s core because of the layers in between until violent earthquakes or volcanoes shake us. In the study of earthquakes, it has been studied that the Earth’s inner core, which is around 7000 KMs wide, has stopped rotating and might have changed its rotating direction to the opposite.
As per the studies at Nature Geoscience, it has been revealed that the rotation of the earth’s inner core came to a grinding halt in 2009, and after that, it started rotating in the opposite direction.
A study from Peaking University revealed that while studying the earthquakes from 1995 to 2021, it found that in 2009, the inner core stopped rotating and might change its direction.
It further stated that the Inner Core rotates like a swing, back and forth. Generally, a swing has a life span of 7 decades, which means it generally changes its direction after 35 years. The last time when the inner core of the earth changed its direction was in 1970, and in the future, it will change its direction by 2040, as per the research of China’s Peaking University.
Earth Layers – Crust, Mantle, & Core
In case, Earth is having 3 layers such as the crust, mantle, and core. The earth’s inner core was first discovered in 1936 when scientists studied earthquake waves traveling through the plane. These waves led to the discovery of the 7000 kilometers of wide Inner core of the earth. As per the studies, the core is made of iron and wrapped inside a liquid iron shell.
One study on nature from 1996 has revealed that the waves which helped in finding the Earth’s Inner core have found some minor but systematic changes in the rotation of the inner core. The rotation rate of the inner core is on the order of 1° per year which is faster than the daily rotation of the other two layers, mantle and crust.
It has been stated that all three layers impact each other, and the rotation of the inner core is directly linked with the length of the day. The observation further says that all three layers, the crust, mantle, and core, have dynamic interactions from the deepest layers to the earth’s surface.
It is still not clear whether the change in the rotation has any effects on human life or not. Once got accurate information, we will update you as well.
So how do you think about how these rotations will affect our life? We have observed various earthquakes in the last couple of weeks. Either we talk about the Anchorage Earthquake, a 4.7 or 5.8 Magnitude Earthquake in Nepal. Are these due to the changes in the rotation of the earth’s inner core, or what?
