The movement of the plates creates three types of tectonic boundaries: convergent, where plates move into one another; divergent, where plates move apart; and transform, where plates move sideways ...

With a computer rendering, he helped scientists understand that the earth, with its shifting tectonic plates, is “an ...

New research suggests that Earth's first crust, formed over 4.5 billion years ago, already carried the chemical traits we ...

The team’s calculations showed the protocrust – Earth’s earliest crust formed during the Hadean eon (4.5-4.0 billion years ago) – would naturally develop the same chemical signatures found in today’s ...

Geologists have made certain assumptions about how the crust making up our planet's earliest surface formed, but a new study ...

The movement of the plates, and the activity inside the Earth, is described as the theory of plate tectonics.

Scientists have long thought that tectonic plates needed to dive beneath each other to create the chemical fingerprint we see in continents.

The modern understanding of the plate tectonic cycle predicts that remnants of submerged plates will be found near subduction zones. However, a new high-resolution model shows that these remnants ...
