The density of the upper part of the lithosphere is

The density of the upper part of the lithosphere is around 2.7 grams per cubic centimeter (g/cm³). The lithosphere is the solid, outermost shell of the Earth that consists of the crust and the uppermost part of the mantle. The density of the lithosphere varies depending on the composition and thickness of the rock layers that make up the crust and upper mantle. The upper part of the lithosphere, which includes the crust and the uppermost mantle, is composed of lighter rocks, such as granite and basalt, that have a lower density than the rocks found deeper in the mantle. This gives the upper part of the lithosphere a lower overall density of around 2.7 g/cm³.
