Analysis of the composition of minerals from the depths opens up new hypotheses for research, says the journal "Nature".
Scientists' hypotheses about the location, composition and size of the nucleus are systematically updated. It is important for scientists not only to reveal all the features of the structure and composition of the nucleus, but it will help in the study of exoplanets. A team of international researchers suggests that the Earth could have “sealed” water reserves not in the soil and oceans, but in the core. The Earth's core can be a huge reservoir of water. This was confirmed by the facts about the siderophilic nature of water during its differentiation between the core and the mantle. The researchers emphasize that they have confirmed the siderophilic nature of water through empirical calculations. This emphasizes that the distribution of hydrogen in the alloy of iron and silicate has been established.
This is also important, because in parallel, scientists in France and the United States have developed a way to study liquid silicates in extreme conditions existing at the boundary of the Earth's core and mantle, and this, they say, could lead to a better understanding of the nature of the core and the processes of its evolution.
In addition, an active study of the composition of the Earth's core can be traced in another vector. Scientists estimate that the Earth's inner core rotates at about 0.05-0.1 degrees per year, according to an analysis of seismic data from recurring earthquakes published in the journal Earth and Planetary Science Letters.
These directions work autonomously, but the most important thing is that the question of the composition of the core, its components and filling is important for the development of the Earth and understanding its future. If the core of the Earth really consists of water, this could solve many questions, scientists say with caution.
