The width of the object at the present time is 420 kilometers.
Geophysicists from the UK and Denmark recorded the formation inside the core of the Earth iron jet. Devoted to a study published in the journal Nature Geoscience.
The jet is formed in the liquid outer core of the Earth in the area under the North pole. The width of the object at the present time is 420 kilometers. Of this size the jet is reached starting from 2000, every year increasing in width by about 40 kilometers.
Geophysicists believe that they open the iron stream is one of the objects that create the Earth’s magnetic field. Their observations the researchers conducted with the help of the mission Swarm — three satellites of the European space Agency, which tracks the magnetosphere of the planet.
The core of the Earth with a radius of 3.5 thousand kilometers is under the mantle at a depth of 2.9 thousand kilometers from the planet’s surface. It is formed by a liquid outer layer thickness of 2.2 thousand kilometers and the solid inner core with a radius of 1.2 thousand kilometers.
