(PhysOrg.com) -- For much of Earth's history, the continents have shifted around, sometimes joining with others, sometimes tearing apart to form new continents. One such shift resulted in what Earth scientists call the Pangaea, ...
Scientists have speculated for some time that the Earth's carbon cycle extends deep into the planet's interior, but until now there has been no direct evidence. The mantle–Earth's thickest layer –is largely inaccessible. ...

Geological history has periodically featured giant lava eruptions that coat large swaths of land or ocean floor with basaltic lava, which hardens into rock formations called flood basalt. New research from Matthew Jackson ...

What spreads the sea floors and moves the continents? What melts iron in the outer core and enables the Earth's magnetic field? Heat. Geologists have used temperature measurements from more than 20,000 boreholes around the ...

(PhysOrg.com) -- Scientists in the US have suggested that volcanic activity in Hawaii could be fed by a giant hot rock pool 1,000 kilometers west of the islands and in the Earth’s mantle, rather than being fed by a hot ...
Parts of the moon's interior contains as much water as the upper mantle of the Earth - 100 times more of the precious liquid than measured before – research from Case Western Reserve University, Carnegie Institution ...

Diamonds that no-one ever sees can form deep in the Earth’s interior. This is due to the chemical conditions controlling the associated carbon cycle. Swiss researchers used laboratory experiments to show how this happens.
