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

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 ...

Scientists discovered Earth's first crust had continental chemical signatures. This challenges beliefs about when these ...

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

Deep beneath the surface of our planet, from the Himalayas to East Africa and from the Atlantic seafloor to the Indian Ocean, ...

Scientists have discovered that a portion of the North American craton is slowly dripping into Earth's mantle, challenging ...

Earth's crust today has a surprisingly similar composition ... crusts made by the process of subduction, in which one tectonic plate slides under another. But plate tectonics isn't actually ...

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.

challenging beliefs about how our continents formed and when plate tectonics began. A study published in Nature reveals that Earth's first crust, formed about 4.5 billion years ago, probably had ...

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