Sentences with phrase «molten outer core»

The key to this understanding are the concepts of a «torque» and the of natural power of «swirling vortices» as these phenomena that relate to the role of the atmosphere, the oceans, the Earth's «molten outer core,» and formation of Earth's magnetic field on climate change.
So figure that molten outer core is insulated by kilometers of dirt and rock... the heat gets out... but slowly.
Richard Gross of NASA who compiled the LOD series in my graph Says that he thinks the LOD variation is due to shifting currents within the Earth's molten outer core and semi-molten sub-mantle regions.
«Says that he thinks the LOD variation is due to shifting currents within the Earth's molten outer core and semi-molten sub-mantle regions.»
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.
We know it comes from the convection of the molten outer core.
Seismic data show that sound waves, descending from earthquakes in the mantle and crust above, slow as they pass through the molten outer core.

Not exact matches

Heat from Earth's inner core, which is as hot as the surface of the sun, churns an outer core of molten iron and nickel, generating a magnetic field that deflects lethal cosmic and solar radiation away from the planet.
Besides having the right mix of ingredients and pressures, this range defines a well - known transition zone within the mantle, the 2900 - kilometer - or - so - thick layer of slowly circulating material that lies between Earth's crust and its outer core of molten iron.
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.
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.
That rules out some previously proposed ways of forming Mercury with its relatively huge molten iron core, such as having the nascent sun blasting away the outer rind of an Earthlike planet.
The mantle, which makes up more than four - fifths of the earth's volume, is energized by radioactive heating within it and by the molten iron outer core below it.
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.
Most of Earth's magnetic field is generated deep within the outer core by an ocean of superheated molten iron.
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.
So, tracking changes in the magnetic field can reveal how the superheated, swirling mass of molten iron in the outer core behaves.
The MESSENGER observations and data from the two earlier Mariner 10 flybys are consistent enough to describe a dipolar field with an active electrical dynamo in which the magnetic field is produced by electrical currents flowing in an outer core of molten metal (more discussion and images from MESSENGER's January 2008 flyby).
Harold Jeffreys, one of the geologists who proved that the Earth's outer core was molten, rejected plate tectonics entirely.
OK correction, the outer core is molten, the inner core is actually solid.
