How are crystals different to grains

WebGrain can be termed as the smaller variation of a crystal. 2. Crystals can be called as large grains. Crystals have a unique arrangement of the molecules or atoms and a lattice … 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.
