Sentences with phrase «fluid outer core»

We demonstrate that the combination of lower estimates of the 20th century GMSL rise (up to 1990) improved modeling of the GIA process and that the correction of the eclipse record for a signal due to angular momentum exchange between the fluid outer core and the mantle reconciles all three Earth rotation observations.

Earth's solid inner core is surrounded by a fluid outer core, with the boundary between the two expected to be the temperature of the melting point of highly pressurized iron — the primary ingredient of both layers.

Rotating independently of the planet, turning at a different speed within a fluid outer core, this solid, satellite - size sphere holds clues to understanding Earth's earliest history and perhaps even life on the planet.

The motion of Earth's fluid outer core, which contains iron and nickel, helps to generate a planet - wide magnetic field.

Not exact matches

Under slightly less pressure, the outer core — a 1,400 - mile - deep, 8,000 - degree ocean of iron and nickel — is still hot enough to be fluid.

Scientists think a dynamo — a rotating, convecting, electrically conducting fluid in a planet's outer core — is the mechanism for generating the planetary magnetic fields.

Their cores may be fluid, but their outer surfaces are solid and extremely tough — making graphene, the strongest material on Earth, look like tissue paper by comparison.

Or it might be associated with chemical reactions between the outer core's iron - rich fluid and the crystalline silicate mantle.»

Dynamos are possible because mechanical energy — in this case the movement of the fluid in the outer core — can generate a magnetic field.
