New research deepens the understanding of Earth's crust by testing and ultimately eliminating one popular hypothesis about why continental crust is lower in iron and more oxidized compared to oceanic ...

Earth's crust ranges from 5 to 70 kilometers in thickness and serves as the planet's outermost layer. This thin shell represents less than one percent of Earth's total mass, yet it's the only layer we ...

In 1981, scientists discovered one of the thinnest portions of the Earth’s crust — a 1-mile (1.6 kilometers) thick, earthquake-prone spot under the Atlantic Ocean where the American and African ...

The formation and composition of oceanic crust remain central yet unresolved questions in plate tectonics. While seismic data suggest a globally uniform crustal thickness (~6 km), petrological ...
