WebThe lithosphere is not an individual layer, but rather a zone made up of two of the layers of the Earth, which includes the crust. The Layers of the Earth The Earth consists of three layers: the crust, the mantle and the core. The core, the innermost layer, is rich in iron and very dense. It can be further subdivided into the inner and outer core. http://ser.sese.asu.edu/GEO110/GEO110_S03/Dis2b.pdf
