The earth's surface is like its skin. Beneath this surface, or crust, there are several more layers of the planet. The hottest area, the earth's solid inner core is 10 percent sulphur. The rest is iron and nickel. The inner core is 800 miles thick. The outer core contains molten, v...
The outer core is approximately 1,367 miles (2,200 km) thick and composed of liquid iron and nickel. Temperatures in the outer core are between 8,132 degrees F and 9,932 degrees F (4,500 degrees C and 5,500 degrees C). Outer core quick facts Thickness: 1,400 miles ( 2,300 km)...
The Earth's core is actually made up of two distinct parts: a 2,200 km-thick liquid outer core and a 1,250 km-thick solid inner core. The outer core is made of iron and is very dense. As the Earth rotates, the liquid outer core spins, creating the Earth's magnetic field. The ...
in the current thermo-compositional state of the Earth’s core, the outer core composition is close to eutectic in most regions resulting in a sharp inner core boundary, but deviation from the eutectic composition exists in some localized regions resulting in a mushy zone with a thickness of 4...
Layers of the Earth including the solid inner core, liquid outer core, mantle, and crust The Earth is made up of several layers, each with its own distinct properties. Here are the primary layers from the outside in: The Crust The crust is the Earth's outermost layer, where all life ...

The thick black line labeled KOCGA is the obtained continuous V p model of the outer 700 km of the core, which has four layers with uniform V p gradients. Other details are the same as Fig. 3. The thickness of the deepest layer is fixed to 400 km and the V p value at the ...
Lower mantle structure, and in particular structure of the mantle just overlying the core is reviewed next. Finally, models of the outer and inner core are described. Connections with the propagation of seismic waves used to image these features are made throughout the chapter....
Helical fluid motions in Earth’s electrically conducting liquid outer core have an electromagneticdynamoeffect, giving rise to thegeomagnetic field. The planet’s sizable, hot core, along with its rapid spin, probably accounts for the exceptional strength of the magnetic field of Earth compared with...
