Parts of ancient Earth may have formed continents and recycled crust through subduction far earlier than previously thought.

A giant underwater canyon system in the Atlantic appears to have formed through tectonic forces rather than erosion.

Most of the time, the shape of Earth’s magnetic field is quite similar to that which would be produced by a bar magnet ...
