New study reveals Earth’s inner core has stopped spinning and may be changing direction

A new study has found that the Earth’s inner core has recently stopped spinning and reversed its direction of rotation. This is an important discovery for our understanding of the Earth’s inner dynamics and the interactions between its layers.

The crust, mantle, and core make up the three groups of layers that make up the Earth. Through the study of seismic waves from earthquakes, the inner core, which is located in the center of the planet, was first identified in 1936. It has a width of about 7,000 kilometers and consists of a liquid iron shell surrounding a massive iron core . According to a 1996 Nature study, there has been a small but consistent change over the past three decades in the amount of time it takes for seismic waves to travel through the Earth’s inner core. The rotation of the inner core, which is about 1 degree per year faster than that of the mantle and crust, is believed to be the cause of this anomaly.

The inner core stopped spinning in 2009 and may be changing direction, according to a recent study from Peaking University. According to the study, which was published in Nature Geoscience, the rotation of the core is affected by variations in the length of the day and can cause small changes in how long it takes the Earth to rotate on its axis.

According to the research team, the observations show evidence of dynamic interactions between the Earth’s layers and could be caused by gravitational coupling and the transfer of angular momentum from the core and mantle to the surface.

The Peaking University research team expects their findings to lead to additional research into the dynamic interactions between the Earth’s layers and how they may affect the past, present and future of the planet. Understanding these interactions is essential to understanding the planet as a whole, even though there is currently no evidence to suggest that the change in the rotation of the inner core harms individuals living on its surface.
