Forbes contributors publish independent expert analyses and insights. An award-winning reporter writing about stargazing and the night sky. Are we alone, and if so, why? So far, the search for ...

image: This shows the mechanisms for the recent Virginia and Oklahoma earthquakes that occurred within the North American plate, and the 2010 Haiti Earthquake that occurred on the plate boundary ...

Ancient plate tectonics in the Archean period differs from modern plate tectonics in the Phanerozoic period because of the higher mantle temperatures inside the early Earth, the thicker basaltic crust ...

For millions of years, Earth’s moving plates have sculpted continents, carved oceans, and built massive mountain ranges. Yet some of these giant structures vanished deep into the mantle, hidden from ...

Earthquakes and volcanism occur as a result of plate tectonics. The movement of tectonic plates themselves is largely driven by the process known as subduction. The question of how new active ...

Geophysicists can use a new model to explain the behavior of a tectonic plate sinking into a subduction zone in the Earth's mantle: the plate becomes weak and thus more deformable when mineral grains ...

A new study makes the case that the solar system’s hellish second planet once may have had plate tectonics that could have made it more hospitable to life. By Kenneth Chang Venus today is not like ...
