WebC. Minerals and rocks are distinguished by the continuity of the material. Minerals are characterized by continuous arrangement of the constituent atoms, whereas rocks are composed of different minerals and hence are inhomogeneous. This homogeneity is exhibited on the optical, physical and chemical properties of the minerals. WebA 10 x 10 cm 2 multicrystalline wafer. The wafer has been textured so that grains of different orientation show up as light and dark.
