The inner layer of the earth has started to rotate in the opposite direction. This claim was made in a new study conducted in China. The upper layer of the earth is based on liquid metal, while the inner layer consists of solid metals and its volume is equal to 70% of the surface of the moon. It was believed that the inner layer of the earth
It rotates counter-clockwise, but Peking University research concluded that the rotation of the inner layer stopped around 2009 and then began to rotate counter-clockwise. We believe that this layer first spins in one direction and then spins in the other direction, the researchers said. He said that this rotation cycle in both directions is completed in 70 years (the cycle of each direction is completed in 35 years). They said that before 2009, the direction of the Earth’s interior had last changed in the 1970s, and the next time it would happen was in the mid-1940s. It should be noted that it is a very difficult task to collect information about the inner layer of the earth because it is located 5 thousand kilometers below the surface. For these studies, the experts analyzed the seismic waves and with their help it was possible to determine the rotation of the inner layer. The researchers compared earthquake records from the 1960s to the 1990s with recent earthquakes, suggesting that the Earth’s rotation stopped in 2009 and then reversed. According to the scientists, a change in the rotation direction of the inner layer causes changes in the length of days and the Earth’s magnetic field. The results of this study were published in the journal Nature Geosciences.
