A new model of the deep Earth allows geophysicists to measure variations in Earth's temperature near the boundary between the rocky mantle and core. Using a recently discovered phase change in the ...

COOK1 has shown that, in the Earth's gravitational potential when developed into a series of zonal spherical harmonics, the coefficients are influenced to the fourth harmonic by the ...

The interior of the Earth, like that of the other terrestrial planets, is chemically divided into layers. The Earth has an outer silicate solid crust, a highly viscous mantle, a liquid outer core ...
