It has an irregular thickness, varying from about 5 km beneath the oceans (oceanic crust) to about 30 km beneath the continents (continental crust).sciencenotes.org/layers-of-the-earth/Beneath the oceans, the crust varies little in thickness, generally extending only to about 5 km. The thickness of the crust beneath continents is much more variable but averages about 30 km; under large mountain ranges, such as the Alps or the Sierra Nevada, however, the base of the crust can be as deep as 100 km.pubs.usgs.gov/gip/dynamic/inside.htmlEarth's crust ranges from 5–70 kilometres (3.1–43.5 mi) in depth and is the outermost layer.en.wikipedia.org/wiki/Internal_structure_of_EarthThe crust can be thicker than 80 kilometers in some spots and less than one kilometer thick in others.
