GEOLOGY

Detailed explanation-1: -Isotropic materials are materials whose properties remain the same when tested in different directions. Isotropic materials differ from anisotropic materials, which display varying properties when tested in different directions. Common isotropic materials include glass, plastics, and metals.

Detailed explanation-2: -More solids belong to the monoclinic system than to any other. Beta-sulfur, gypsum, borax, orthoclase, kaolin, muscovite, clinoamphibole, clinopyroxene, jadeite, azurite, and spodumene crystallize in the monoclinic system.

Detailed explanation-3: -If a linearly elastic solid has one plane of material symmetry, it is called a monoclinic material.

Detailed explanation-4: -Examples of anisotropic materials include graphite (such as in pencils), wood, and carbon fiber. Although, any material that exhibits a difference in a material property (chemical, thermal, or electrical) across different parts of the material can be considered anisotropic.
