The density of the earth's crust varies from

The density of the earth's crust varies from 2.5 g/cm3 to 3.3 g/cm3. The Earth's crust is the outermost layer of the Earth, and is composed of various minerals and rocks. The density of the crust varies depending on its composition, with lighter minerals like quartz and feldspar having lower densities than heavier minerals like iron and magnesium. Overall, the average density of the Earth's crust is around 2.7 g/cm3, which is much lower than the densities of the Earth's mantle and core. It is important to note that the density of the crust can also vary locally depending on factors like the presence of mineral deposits or the formation of mountains and other geologic features.
