Scientists have stated that the Earth's magnetic field has been steadily weakening over the last 160 years, which could have catastrophic consequences.

It is already known that the weakest part lies in the territory that extends from Chile.
Moreover, according to the experts, such a phenomenon could lead to a modification of the poles and a new increase in the concentration of cosmic rays reaching the surface of the Earth.
It is interesting to note that the Earth's magnetic field protects all living organisms from dangerous cosmic radiation.
At the beginning of the year, a group of researchers stated that the intensity of the magnetic field was gradually decreasing, whereas this process was uneven.
it decreased an average of 1.7% on average and, in certain regions, for example in the South Atlantic Ocean, by 10%. In some places, the intensity of the magnetic field has even increased, contrary to the general trend.
However, immediately afterwards, scientists noted that changes in the magnetic field structure had occurred earlier, claim that it has weakened between 400 and 450, 700 and 750 and 1225- Scientists note that such changes are due to the displacement of a huge reservoir of dense rocks located between the core and the mantle.
These rocks can affect the equilibrium of the iron, which allows to generate the magnetic field of the Earth [19659011] "We are increasingly convincing Proof that there is something d & # 39; unusual at the boundary between the core and mantle under the African continent, which may have a significant effect on the global magnetic field, – the University of Rochester.
However, it should be noted that scientists are rarely able to detect the remains of predatory reptiles, which lived in the Lower Jurassic (there is 201-174 million years), but paleontologists of the Museum of Natural History of Milan made it incredible. [19659002]
In the 80 km north of Milan, they found bones belonging to an unknown dinosaur species. Researchers named him Saltriovenator zanellai
As scientists discovered, S. zanellai weighing about a ton lived on Earth 198 million years ago, the dinosaur detected at the time of his death was only 24 years old. Representatives of large species at this age continue to grow. From this point of view, paleontologists have suggested that adult S. zanellai individuals have an order of magnitude greater.
Remember, people were shown how Mars would change face.
Also, "Znay.ua" wrote that astrologers had said that they would give each zodiac sign until 2019.
