A new study has changed what scientists thought they knew about Earth’s early history. Researchers have discovered that the ...

Earth’s earliest crust, formed over 4.5 billion years ago, has long been thought to have lacked the complex chemical features ...

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

What happens, then, to keep the Earth the same size? The answer is subduction. In locations around the world, ocean crust subducts, or slides under, other pieces of Earth's crust. The boundary ...

It’s long been thought that tectonic plates needed to dive beneath each other to create the chemical fingerprint we see in ...

This week, researchers reported on nine rivers and lakes in the Americas that defy hydrologic expectations. Geologists report ...

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

This phenomenon leads to the gradual disintegration of stable continental crust. Experts suggest that subduction—where a denser mantle layer is pushed beneath another—and mantle plumes ...

In geography, taking a slice through a structure to see inside is called a cross section. Continental plates are usually quite thick (between 35 to 70 km) compared to the much thinner oceanic ...

a long timescale with multiple subduction events is needed to hydrate the MTZ and possibly trigger intraplate volcanic activity. The link between water storage in the MTZ and continental ...

Gather your supplies! In this episode we will use everyday materials to learn about tectonic plates and fault lines.
