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

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

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

Beneath the surface of the United States, the Earth's crust is gradually subsiding, creating a novel geological phenomenon.

Seismic mapping of North America has revealed that an ancient slab of crust buried beneath the Midwest is causing the crust ...

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

Earth is the only known planet which has plate tectonics today. The constant movement of these giant slabs of rock over the ...

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

A study published in Nature on 2 April reveals that Earth's first crust, formed about 4.5 billion years ago, probably had chemical features remarkably like today’s continental crust. This ...

Earth's first crust, formed around 4.5 billion years ago, likely had chemical features similar to today's continental crust, suggesting that the distinctive chemical signature of continents was ...

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 ...
