Recent discoveries offer deeper insight into the movement of tectonic plates. New research has found that variations in rock ...

Earth's crust today has a surprisingly similar composition to the planet's first outer shell, or "protocrust," new research ...

Over 4.6 billion years ago, Earth took shape from a spinning cloud of dust and gas surrounding the young sun. Tiny particles ...

Earth is the only known planet which has plate tectonics today. The constant movement of these giant slabs of rock over the planet's magma creates continents - and may have even helped create life.

Watch the Earth's tectonic plates grow, shrink, and jostle for position in this new model of the last billion years on the ...

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

The oldest crust on Earth, known to be unchanging, is actually being altered in real time. The North American continent is ...

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

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

Even the oldest and most stable of lithospheric structures can’t withstand geologic machinations deep within the Earth.
