As the Aral Sea has been drained by irrigation and dried up, the mass loss on the surface has caused Earth’s upper mantle to rise up, lifting the emptied sea bed an average of 7 millimetres per year ...

The Earth has a layered structure made up of the core, the mantle and the crust. Different elements are present in different parts of the Earth’s structure. The crust is made from enormous ...

New research reveals a surprising link between the ancient tectonic history of oceanic plates and their fate as they subduct ...

New calculations indicate a strong episodicity in mass flux across the 660 km depth when realistic mantle parameters are used (W. R. Peltier, Univ. Toronto, Canada), but in a time-averaged sense ...
