* Oceanic crust: 3-5 miles (5-8 kilometers)
* Continental crust: 20-30 miles (30-50 kilometers)
Important notes:
* Average thickness: This is just an average. The thickness can vary significantly within these ranges.
* Thinnest and thickest points: The thinnest crust is found at mid-ocean ridges, while the thickest crust is found beneath mountain ranges.
* Different types of crust: The crust is divided into oceanic crust (found under the oceans) and continental crust (found under the continents).
So, depending on where you are on Earth, the crust can be as thin as 3 miles or as thick as 30 miles.
