In geology, a crust is the outermost solid shell of a planet.

Earth has the best characterized and perhaps the most complex crust of all the planets and moons in our solar system. An overview of our crust is provided in the entry on Structure of the Earth. Earth's crust occupies less than 1% of Earth's volume.
