Webb23 maj 2024 · The five platonic solids are the tetrahedron (4 triangles), cube (6 squares), icosahedron (20 triangles), octahedron (8 triangles) and dodecahedron (12 pentagons). Why do minerals have geometric shapes? As discussed, the shape is a natural form that they mineral will take as the crystal grows. Recognizing the habit can aid in mineral identification and description, as the crystal habit is an external representation of the internal ordered atomic arrangement. Most natural crystals, however, do not display ideal habits and are commonly malformed. Hence, it is also important to describe the quality of the shape of a mineral specimen: • Euhedral: a crystal that is completely bounded by its characteristic faces, well-formed. Synonym…
