Oceans apart: New research suggests that ocean-crust formation is a dynamic process
Three-fifths of Earth’s crust lies underwater, spread out along the seafloor. More than four cubic miles of ocean crust forms each year, constantly regenerating like new skin across the globe. This ocean ...

Crust (geology)
In geology, a crust is the outermost solid shell of a rocky planet or moon, which is chemically distinct from the underlying mantle. The crusts of Earth, our Moon, Mercury, Venus, Mars, Io, and other planetary bodies have been generated largely by igneous processes, and these crusts are richer in incompatible elements than their respective mantles.
