The mysterious core of the Earth is stranger than we think. Scientists do not understand exactly how it works either, but recent studies show that they are beginning to unravel the secret of the furnace. The Earth’s core behaves like a huge sphere of solid metal. Scientists have found that the Earth’s core can rotate, and in fact, according to a study, the core may have recently stopped and started moving in the other direction. However, there is no reason to panic, since the same thing probably happened in 1971; but despite this, the researchers continue to investigate, since “they don’t want something happening in the depths of the Earth that they don’t understand”. Earth’s core keeps growing The radius of the inner core grows by about one millimeter every year – we’ve known this for a long time. However, according to a 2021 study, the core grows laterally. This does not mean that it can even grow into a soccer ball, but according to scientists, the crystals appearing on one side of the core can rearrange to the other side in order to maintain its spherical shape. And this information tells us the same about the mantle above the core: it is likely that one side of the mantle is slightly cooler than the other. However, the question is whether all this can change the strength of the magnetic field. Could there be giant mountains and an oceanic crust beneath us? The Earth’s magnetic field between South America and Africa is constantly weakening, for which, in principle, the core could be to blame. The anomaly above the continents is an area that is believed to receive slightly more solar radiation. People are still safe from the radiation, but satellites take more damage when they pass through this zone. In addition, the anomaly has grown larger over the past 50 years and has begun to split into two spots. According to the research group’s latest study, giant mountains five times higher than Everest can keep the Earth’s core warm. It is also hypothesized that an ancient oceanic crust hugs the Earth’s core, the result of a past tectonic process. However, additional measurements are needed to prove this. Source
