OUTER CORE:

Earth's Inconstant Magnetic Field
The inner core is 70% as wide as the moon. It spins at its own rate, as much as 0.2° of longitude per year faster than the Earth above it, and it has its own ocean: a very deep layer of liquid iron known as "the outer core."
Volume 651, number 2: Transitions between Turbulent and Laminar
We investigate the global ition from a turbulent state of superfluid vorticity (quasi-isotropic vortex tangle) to a laminar state (rectilinear vortex array), and vice versa, in the outer core of a neutron star.
Seismologists Measure Heat Flow From Earth's Molten Core Into The
As heat flows from the outer core into the mantle, it drives important processes in both the mantle and the core. The mantle is a thick layer of silicate rock that surrounds a dense, predominantly iron core. The outer core is molten
Seismolgists get handle on heat flow deep in Earth
"Understanding of Earth's core-mantle boundary environment puts us in the position of answering a host of important questions, such as how much heat from the molten outer core cooks the overlying mantle," Garnero explained.
Earth's polarity may reverse in mere 1000s of years!
One possibility:- The Earths solid inner core — surrounded by a circulating, convecting magnetic field-generating outer core — is getting bigger, which theoretically should be steady over the eons. During this period, the Earths
Inner and outer core; Myspace and Real Life
I can only speak for myself here, but I feel we all have inner and outer cores. On myspace most people only get to know the outer core of a person, which doesn't say a whole lot. We tend to summerize
Sulfur's impact on core evolution and magnetic field generation on
In the Earth, convection in the outer core is driven by some combination of thermally-generated buoyancy as the core cools and compositional buoyancy from the release of some light element at the inner core outer core boundary and then
Structure of the Earth
Why is the inner core solid, the outer core liquid, and the mantle solid/plastic? The metallic nickel-iron outer core is liquid despite the enormous It is generally believed that convection in the outer core, combined with
EARTH
The inner core and crust are solid; the outer core and mantle layers are plastic or semi-fluid. The various layers are separated by discontinuities which are evident in seismic data; the best known of these is the Mohorovicic
Re: Jose Arguelles
"Though nearly pure iron, the outer core is thought to have the consistency of water, and convection in the outer core is thought to create the Earth's magnetic field. At the bottom of this ocean of iron, however, iron crystals settle

LiveScience.com - Earth's Core Rotates Faster than Surface, Study
The core consists of a solid inner core and a fluid outer core. The fluid contains iron, which, as it moves, generates the Earth’s magnetic field.
Earth's Structure
The outer core is about 1370 miles (2200 km) thick. Because the earth rotates, the outer core spins around the inner core and that causes the earth's
Science News Online - This Week - News Feature - 7/20/96
The surface of the core, at its equator, is moving about 20 km per year relative to the liquid outer core. "That's 100000 times faster than the types of
Geodynamo
Our solution illustrates how the influence of the Earth's rotation on convection in the fluid outer core is responsible for this magnetic field structure

Outer core density heterogeneity and the discrepancy between PKP
We derive 3-D tomographic maps of the Earth's mantle, CMB and outer core, from seismic P, PcP, PKPbc, PKPdf travel time data, based on the bulletins of the
Estimating lateral structure in the Earth’s outer core
Lateral density structure could exist in the Earth’s fluid outer core, owing to the gravitational perturbations induced by the asphericity of the mantle.
