This early rocky shell featured chemical signatures previously thought to occur only in continental crusts made by the ...

The tiny Juan de Fuca plate is largely responsible for the volcanoes ... The movement of the plates creates three types of tectonic boundaries: convergent, where plates move into one another ...

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

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

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

In this episode we will use everyday materials to learn about tectonic plates and fault lines. A subduction fault is when two plates have different densities. So, when a heavier oceanic plate ...

Iceland’s volcanic activity is generally tame compared with explosive eruptions along the Pacific’s Ring of Fire. This time, it’s shaking up a town.

The Earth is made of different layers: the core, mantle and crust. Plate tectonic theory shows that the crust of the Earth is split into plates (pieces of the Earth’s crust). The movement of ...

Researchers have discovered that the underside of the North American continent is dripping away in blobs of rock—and that the remnants of a tectonic plate sinking in Earth's mantle may be the ...
