New Study Explains Earth’s Rotation Changes
A recent study reveals that the changes in the Earth's rotation speed over the decades are primarily due to deep processes within the planet, where gravitational interactions play a more significant role than electromagnetic and topographical mechanisms. The findings indicate that this interaction contributes to the acceleration or deceleration of Earth's rotation, noting that the length of Earth's days has gradually become shorter since the 1970s, with minor variations amounting to parts of a thousandth of a second. The study explains that processes within the Earth's interior—specifically the interactions between the core and the mantle—play a crucial role in these temporally managed changes over decades, helping to better understand the causes of fluctuations in the planet's rotation speed.
