Sentences with phrase «solid iron core»

SO just HOW can we justify that that the outflow in the computer MUST be less than inflow for the 250 years of the computer run, when clearly the daily temperature cycle will reestablish the equilibrium (at least for the atmosphere & ground — not sure about deep ocean equilibrium, BUT I also know that there is MUCH MUCH MORE energy stored in the Land (eg solid iron core of earth) than in the ocean & the GCMs do NOT address this either).

THE Earth's solid iron core may recycle itself every 100 million years, melting on one side and resolidifying on the other.

The first hint that Earth actually had a solid iron core beneath a liquid layer came in 1929, after a magnitude - 7.8 earthquake shook New Zealand.

Not exact matches

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.

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.

Earth's inner core is a solid iron ball slightly smaller than the moon.

The cores of both Mercury and Earth contain light elements such as sulfur, in addition to iron; the presence of these light elements keeps the cores from being completely solid and «powers the active magnetic field - generation processes,» Hao said.

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.

To mimic conditions at Earth's Core, scientists cranked up the heat and pressure, then used synchrotron X-rays to gauge when iron turned from solid to liquid.

Sorting through 40 - year - old records of moonquakes (red dots) has apparently revealed a liquid - iron core (yellow) and a solid - iron inner core (orange).

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.

It is widely accepted that the Earth's inner core formed about a billion years ago when a solid, super-hot iron nugget spontaneously began to crystallize inside a 4,200 - mile - wide ball of liquid metal at the planet's center.

The exact thickness of that layer is unknown, but as it gradually cools, it should form solid chunks that sink like iron snow into the denser, solid inner core, also of unknown size, says geophysicist Sean Solomon of the Carnegie Institution of Washington's Department of Terrestrial Magnetism, the mission's principal investigator.

We know that the planet has a partly solid, partly liquid core, composed largely of iron, surrounded by a thick, flowing mantle, topped by a thin layer of crust.

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.

There's the familiar thin crust of continents and ocean floors; the thick mantle of hot, semisolid rock; the molten metal outer core; and the solid iron inner core.

The explosion is hot enough to fuse elements far heavier than iron, and it releases these elements in a gaseous cloud that will become an asymmetrical remnant around the remaining, solid core [source: Chandra X-ray Observatory].

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.

Geologists have long believed that Earth's core, a solid ball the size of our moon, consists primarily of an iron - nickel alloy and is uniform in composition throughout.

Our planet's magnetic field is generated by molten iron swirling around in the planet's outer core around a smaller, solid core — a process that creates a self - sustaining geomagnetic dynamo.

They deduce that the planet has a solid inner core surrounded by a relatively thin, molten outer core, which is possible if the core contains some sulphur as well as iron.
