Much deeper, the outer core is liquid, with a viscosity similar to water.

The planetary architecture that provides Earth's sheltering field has been broadly understood for several decades now: a solid - iron inner core roughly the size of the moon, surrounded by a 1,400 - mile - thick outer core of liquid iron and nickel, with 1,800 miles of solid mantle above, topped by a crust of slowly drifting tectonic plates.

Scientists had recently discovered that every 200,000 years, on average, churning in the hot liquid metal of Earth's outer core causes the planet's whole magnetic field to flip.

Two years ago, a team of scientists from two British universities discovered that liquid iron, at the temperatures and pressures found in the outer core, conducts far more heat into the mantle than anyone had thought possible.

The discovery is vexing: If liquid iron conducts heat into the mantle at such a high rate, there wouldn't be enough heat left in the outer core to churn its ocean of liquid iron.

Those light elements would then rise into the liquid outer core, creating convection currents.

The researchers show that this effect could continuously stimulate the motion of the liquid iron alloy making up the outer core, and in return generate Earth's magnetic field.

Sitting on top of the liquid outer core, it may sink slightly, disturbing the flow of iron and ultimately affecting Earth's magnetic field.

The region is located right above the boundary between the hot liquid outer core and the stiffer, cooler mantle.

This shield is produced by the geodynamo, the rapid motion of huge quantities of liquid iron alloy in the Earth's outer core.

The underside of the mantle — the boundary between it and the liquid outer core — is probably rugged terrain.

This mechanical forcing applied to the whole planet causes strong currents in the outer core, which is made up of a liquid iron alloy of very low viscosity.

The magnetic field is generated by swirling, liquid iron in Earth's outer core.

The Outer Core Made of molten iron, nickel, and other ingredients yet to be determined, the churning liquid outer core may have the viscosity of water, streaming at possibly one to several miles per week with the turbulence of a gargantuan, slow - moving washing macOuter Core Made of molten iron, nickel, and other ingredients yet to be determined, the churning liquid outer core may have the viscosity of water, streaming at possibly one to several miles per week with the turbulence of a gargantuan, slow - moving washing machCore Made of molten iron, nickel, and other ingredients yet to be determined, the churning liquid outer core may have the viscosity of water, streaming at possibly one to several miles per week with the turbulence of a gargantuan, slow - moving washing macouter core may have the viscosity of water, streaming at possibly one to several miles per week with the turbulence of a gargantuan, slow - moving washing machcore may have the viscosity of water, streaming at possibly one to several miles per week with the turbulence of a gargantuan, slow - moving washing machine.

To obtain this result, they modeled Earth's outer core using liquid sodium enclosed between two rotating concentric metal spheres, a set - up they dubbed the Derviche Tourneur Sodium (DTS) experiment.1

The Earth's magnetic field is generated by the flow of liquid iron, an electrical conductor, in the Earth's outer core, between 3000 and 5000 kilometres beneath the surface.

This ocean of liquid metal, the outer core, surrounds the inner core, which is made of solid metal.

Below the mantle is the outer core, composed of liquid, molten iron and nickel, which envelopes an inner core of solid iron at the center of the planet.

Two of them are like the ones in the Earth: one separating the solid inner core and the liquid outer core, and the other one separating the outer core and the mantle.

The Earth has an outer silicate solid crust, a highly viscous mantle, a liquid outer core that is much less viscous than the mantle, and a solid inner core.

Mercury's peculiar magnetic field provides evidence that iron turns from a liquid to a solid at the core's outer boundary, say the scientists, whose research currently appears online in the journal Geophysical Research Letters and will be published in an upcoming print edition.

Within Earth's core, iron turns from a liquid to a solid at the inner boundary of the planet's liquid outer core; this results in a solid inner part and liquid outer part.

Every now and then the earth's magnetic field, which here points north and down, would reverse and point south and up, all due to the convection of the liquid outer core of the earth.

The new data should help scientists better model the movement of liquid iron in the outer core, which gives rise to Earth's magnetic field, says Duncan Agnew, a geophysicist at Scripps Institution of Oceanography in San Diego, California.

By looking in detail at the seismic record, you can deduce that Earth has a liquid outer core and a solid inner core, and that both are mostly iron.

The Earth also has a magnetic field that is generated in the outer core, in the liquid part.

The core of the Earth contains an inner layer, an iron - rich solid ball, and an outer layer, of liquid iron and nickel, with a mantle of silicate.

Earth has one, generated by hydrodynamic convection between its liquid outer core and solid inner core.

Its speed of over 25 miles a year is three times faster than the typical speed of liquid in the outer core and hundreds of thousands of times faster than the speed at which Earth's tectonic plates move.

The motion of liquid iron in the outer core is itself driven by the continuous loss of heat from the inner core.

Earth's magnetic field is thought to be generated largely by an ocean of superheated, swirling liquid iron that makes up Earth's outer core 3000 km under our feet.

Also, Earth's magnetic field comes from a liquid outer core circling around a solid inner core.

The author speculates that since it is liquid the outer core is also affected by gravitational tidal forces, in a similar manner to the oceans, but also it can be assumed that the magnetic field generating would act as a brake on its movement.

Except for the liquid outer core, most of the Earth takes the form of a rheid, a form of solid that can move or deform under pressure.

The thermal convection forces are in large part modulated by temperature difference between solid inner and liquid outer core, which due to the bulge is not equatorially even.

Could it be that the expansions and contractions within Earth's liquid outer core are following the 100 year (50 yr.

For example, geophysicists start in the centre of the Earth with the Solid Inner Core extending through the Liquid Outer Core, the Mantle and the crust.
