Scientist discover ‘jet stream’ of molten iron under the surface of the earth


Geo-scientists have made a groundbreaking discovery deep in the Earth’s molten core, the Nature Geo-science journal has published a new study that provides evidence of ‘jet stream’ of liquid metal 3,000 kilometers below Earth’s surface, flowing westwards under Siberia and Alaska.

One of the clearest views of inside the Earth was obtained by the European Space Agency using the latest data gathered by the Swarm which is series of satellites which were launched in 2013.

With the help of data gathered by Swarm geoscientists discovered a ferocious hot jet stream of molten iron flowing in a circular pattern, the jet stream is almost 260 miles wide and it is located under Siberia and Alaska in the north pole.

The jet stream is flowing at a speed of 25 miles per year which in geographical terms is considerably fast as this speed is astronomically higher than the speed of the tectonic plates.

Dr. Chris Finlay from the National Space Institute at the Technical University of Denmark and one of the authors of the paper said:“That might not sound like a lot to you on Earth’s surface, but you have to remember this a very dense liquid metal and it takes a huge amount of energy to move this thing around and that’s probably the fastest motion we have anywhere within the solid Earth.”

According to the scientists the molten iron jet stream may be the result of its close proximity to two boundary regions of Earth’s core, the molten iron is propelled like a jet stream when it comes to the boundary from both sides.

There is no information about the depth of the molten flow yet.

Our Earth is made up of four layers The crust is the outermost layer and every thing is standing on this layer.
The mantle is the second layer and it is 1,800 miles thick, it is composed of rocky silicate and makes up 84% of Earth’s total volume.

The Outer Core is the third layer of molten iron and nickel, it is spinning at a fast speed and the jet stream of molten iron was also found in this year.

The Inner Core comes next and it is a giant ball of iron with temperature as high as the sun.

Swarm has provided scientists an “x-ray” picture of the Earth for the first time which has revealed the presence of a jet stream of molten iron.

Lead scientist Phil Livemore of the University of Leeds said: “The European Space Agency’s Swarm satellites are providing our sharpes x-ray image yet of the core. We’ve not only seen this jet stream clearly for the first time, but we understand why it’s here.”
