Modern continental rocks carry chemical signatures from the very start of our planet's history, challenging current theories about plate tectonics.

The study also provides a new approach to solving one of the biggest enduring scientific mysteries: when did plate tectonics ...

Researchers have made a breakthrough discovery that changes our understanding of Earth's early geological history, ...

In the latter case, high temperatures and pressures lead to the reworking of the crust, affecting its composition, as well as that of the underlying mantle. Furthermore, when two continental ...

Continental and oceanic plates all fit together to form the outer crust of the planet. Eight major plates are named on the diagram below. Heat from the core makes magma in the mantle rise towards ...

New crust is continually being pushed away from divergent boundaries (where sea-floor spreading occurs), increasing Earth's surface. But the Earth isn't getting any bigger. What happens ...

Currents of magma within our planet move the plates that form the continental crust in a constant process that builds mountains and creates valleys. These valleys may eventually become lakes ...

Situated on the west coast of the island of Newfoundland, the park provides a rare example of the process of continental drift, where deep ocean crust and the rocks of the earth's mantle lie exposed.
