The relation between gravity anomalies, topography and volcanism can yield important insights about the internal dynamics of planets. From the power spectra of gravity and topography on Earth, Venus and Mars we infer that ...

Earth's orientation relative to its spin axis is determined by its nonhydrostatic inertia tensor. We show here that the present‐day nonhydrostatic inertia tensor can be modeled by combining contributions due to large low ...

Diamonds are formed under high pressure more than 150 kilometres deep in the Earth’s mantle and are brought to the surface mainly by volcanic rocks called kimberlites. Several thousand kimberlites have been mapped on various ...
