Cientists Found a Huge 'Jet Stream' of Liquid Iron Within Earth's Core and It's Moving Fast
Posted on Mar 20, 2017
There was an amazing revelation about the discovery of a huge liquid flowing through the outer part of Earth's core and it's moving fast.
1. Scientists Discovered a Strange Liquid That Moves 30 Miles Per Year
And it is estimated that the liquid will be making its way beneath Siberia and Alaska but it is not estimated when.
2. The Liquid Moves with the Help of Our Planet's Magnetic Field
The liquid stream is actually iron in liquid form and that explains why the magnetic field is helping it move.
3. "It's a Very Dense Liquid Metal, and Takes a Huge Amount of Energy to Move This Thing Around"
A Danish scientist called Chris Finlay elaborated.
4. He Also Says That It Could Be "The Fastest Motion We Have Anywhere Within the Solid Earth"
The huge stream is 260 miles wide. Also, its size increases by 31 miles every year.
5. The Molten Metal Stream Could Be Ancient
It's 1860 miles under the surface but nobody knows if it will stop expanding. It could be getting more powerful each year and scientists don't know how it would affect the core and our planet in general.
6. Scientists Are Trying to Find Out What Caused That Stream of Liquid Metal
They believe that it appeared because it is so close to two layers of the Earth's core.
7. How Was It Discovered?
ESA's Swarm satellites were the first to capture this liquid because their main focus is the weakening of the magnetic field.
8. One of the Boundaries Next to Which the Metal Flows Is Known as the 'Tangent Cylinder'
The tangent cylinder resembles a tube and it is next to the axis of Earth, and that's why the liquid affects it.
9. How Did We Not Know About It Until Now?
Technological advances managed that the scientists find out about it now.
10. We Know Hold Wide It Is, but Not How Deep It Is
But it is something that scientists are still working on since this is a relatively new discovery.
11. No Need to Panic
It doesn't have to be a threat. With the technological advances, scientists will surely be able to find out everything about the liquid.
