See all on Wikipediahttps://en.wikipedia.org/wiki/Earth's_crustThe crust of Earth is of two distinct types: Oceanic: 5 km (3 mi) to 10 km (6 mi) thick [4] and composed primarily of denser, more mafic rocks, such as basalt,... Continental: 30 km (20 mi) to 50 km (30 mi) thick and mostly composed of less dense, more felsic rocks, such as granite. See more

Earth's crust is a thin shell on the outside of Earth, accounting for less than 1% of Earth's volume. It is the top component of the lithosphere, a division of Earth's layers that includes the crust and the upper part of the mantle. The lithosphere is broken into tectonic plates that move, allowing heat to escape from the interior of Earth into space.
