Tectonophysics: Earth's interior-composition and stateWe compare a theoretical prediction of the equation of state of iron at high pressures and temperatures to the properties of the Earth's inner core. The theoretical result is based on a first principles treatment of the static pressure and the...
Crust - The thinnest layer composing only 1% of the planet; includes all of the land and oceans. Mantle - The majority of the Earth; is made of liquid magma and solid rock. Outer core - Made of liquid iron and nickel; is around 2,200 km thick (1,367 miles). Inner core - The c...
the inner core. The study of short-lived isotope systems shows that the core could have formed early in the Earth's history within about 30-50 Myr after the formation of the Solar System, t(0) = 4567.2 +/- 0.5 Ma. Studies on the partitioning of siderophile elements between liquid iron...
The Earth's core is the hottest region due to its depth, the left-over heat from Earth's violent past and the decay of heavy radioactive elements such as uranium and plutonium. Even though the inner core of Earth is ~5,430 degrees Celsius, it is likely mostly solid due to the intense...

What is Earth made of? Interestingly enough, we don't exactly know. We can use magnetic fields and seismic waves to measure the densities and movements of material deep in the mantle, liquid outer core, and solid inner core of the Earth, which provides clues about its composition. We know...
Inner Core: 18. The inner core is made of solid iron and nickel because it is the innermost region of earth. Since it is under such extreme pressure, the metals become a solid. 19. The inner core has the highest temperatures of all the layers. ...
Density contrasts between the inner and outer core boundary are used to suggest the presence ( 10 ± 5%) of a light element or a combination of elements (e.g., O, S, Si) in the outer core. The core is the dominant repository of siderophile elements in the Earth. The limits of our...
