Sentences with phrase «liquid outer core»

The region is located right above the boundary between the hot liquid outer core and the stiffer, cooler mantle.
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 machine.
Deep inside Earth, slow - motion convection of rocky minerals in the mantle and heat loss from the cooling solid inner core cause convection in the liquid outer core.
Those light elements would then rise into the liquid outer core, creating convection currents.
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 underside of the mantle — the boundary between it and the liquid outer core — is probably rugged terrain.
This artist's view depicts the different layers of the Earth and their representative temperatures: crust, upper and lower mantle (brown to red), liquid outer core (orange) and solid inner core (yellow).
By analogy, the sodium therefore represents the liquid outer core.
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.
To release heat from the liquid outer core, the solid rock in Earth's mantle moves in slow, convective swirls, like a churning pot of hot syrup.
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.
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.
The variations stem from momentum shifts between Earth's liquid outer core and the solid mantle that overlies it, Morrison explains.
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.
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 shift could either be the result of plate tectonics (the individual motion of continental plates with respect to one another) or «true polar wander,» in which the Earth's solid land mass (down to the liquid outer core almost 1,800 miles, or 3,000 kilometers, deep) rotates together with respect to the planet's rotational axis, changing the location of the geographic poles, Mitchell said.
Earth has one, generated by hydrodynamic convection between its liquid outer core and solid inner core.
Also, Earth's magnetic field comes from a liquid outer core circling around a solid inner core.
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.
Could it be that the expansions and contractions within Earth's liquid outer core are following the 100 year (50 yr.
