This formed rocks called gabbros. Studying the channels through which molten rock is transported through the mantle can tell us about how the mantle melts and feeds volcanoes and gabbros. As the rocks ...

The study, which used a computer model to simulate these planets, revealed three probable types —those with a liquid molten mantle, those where a magma ocean lies on the surface and a third ...

Two impactors, back-to-back, would have punched right through the 10-kilometer-thin crust on the Venusian surface, and splooshed into the molten mantle below. Magma would have bubbled up to the ...

The first surface samples retrieved from the dark side of the moon show that there used to be erupting volcanoes there, just ...

(This includes the crust and uppermost part of the mantle.) Churning currents in the molten rocks below propel them along like a jumble of conveyor belts in disrepair. Most geologic activity stems ...
