The Earth crust is made up with two layers known as " sial"and "sima". "sial" is the uppermost layer which composition is silica(si) and aluminum(al), that's why it is call "sial" and this layer comprises all the three rock types i. e. Igneous, sedimentary and Metamorphic rock. The second layer "sima" is formed with silica(si) and magnesium(ma). "sima' is generally composed of Basaltic rock.
