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

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

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 suggests the ...

A recent study challenges previous geological assumptions, revealing that Earth's initial protocrust closely resembled the ...

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

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 ...
