How far is the Earth's crust from the Earth's surface?

The Earth's crust is an extremely thin layer of rock that makes up the outermost solid shell of our planet. In general, then, there are two kinds of crust: oceanic crust (basaltic) and continental crust (granitic). read more

The distance between the Earth's crust to the Earth's core is approximately 3,958 miles. Of this distance, the crust only makes up approximately 21 miles. Between the crust and the outer core is the mantle, which spans a distance of 1,774 miles. read more

Oceanic crust covers about 60 percent of the Earth's surface. It is is 5 km to 10 km thick. Continental crust is thick and old, it ranges from 30 km to 50 km in thickness and is mostly composed of slightly less dense rocks than those of the oceanic crust. read more

Oceanic crust covers about 60 percent of the Earth's surface. Oceanic crust is thin and young -- no more than about 20 km thick and no older than about 180 million years. Everything older has been pulled underneath the continents by subduction. read more
