Algae, bacteria, and mosses that grow on the surfaces of rocks produce weak acids that eventually break the rocks apart. 4. However, in a case where magma does not have enough silica relative to the magnesium oxide to produce the pyroxene, the magma will compensate by making a magnesium-olivine (forsterite; Mg2SiO4), along with the pyroxene, since the olivine requires only one-half as much silica for every mole of magnesium oxide. slowly.

Two moles of SiO2 are needed to be combined with one mole each of CaO and Al2O3 to make the calcium-rich plagioclase, CaAl2Si2O8 (anorthite).
