Geologists have made certain assumptions about how the crust making up our planet's earliest surface formed, but a new study has found that Earth's very first protocrust was surprisingly similar to ...

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 ...

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 ...
