Beyond the outer core lies the mantle, a 1,800-mile-thick layer of viscous molten rock on which Earth's outermost layer, the crust, rests. On land, the continental crust is an average of 19 miles ...

The Earth's interior is composed of four layers, three solid and one liquid—not magma but molten metal, nearly as hot as the surface of the sun. The deepest layer is a solid iron ball, about ...

Crust The crust is the outer layer of the Earth on which we live. It is the thinnest layer and is between 5 and 90 km thick. Earth is divided into four layers: the inner core, the outer core ...

New research suggests that ancient Mars may have been more geologically and hydrologically active than we once thought.

A new study explores how variations in Mars' crustal thickness during its ancient history may have influenced the planet's magmatic evolution and hydrological systems. The research suggests that the ...
