GEOLOGY

Detailed explanation-1: -Additionally, all crystal structures, including the cubic crystal system, are anisotropic with respect to certain properties, and isotropic to others (such as density).

Detailed explanation-2: -Cubic crystals are isotropic for many properties, including thermal and electrical conductivity, but crystals with lower symmetry (such as tetragonal or monoclinic) are anisotropic for those properties. Many (but not all) physical properties can be described by mathematical quantities called tensors.

Detailed explanation-3: -Wood, composite materials, all crystals (except cubic crystal) are examples of anisotropic materials. These materials are direction-independent. These materials are direction-dependent. These materials have a single refractive index.

Detailed explanation-4: -Crystalline solids (except cubic crystals) are anisotropic in nature, that is, some of their physical properties like electrical resistance or refractive index show different values when measured along different directions in the same crystals.
