Orthorhombic is a term used in crystallography to describe a specific type of crystal system. In this system, crystals have three axes that are all of different lengths and are oriented at right angles to each other. This unique arrangement results in a variety of shapes and structures, making orthorhombic crystals distinct from other crystal systems like cubic or tetragonal. Common examples of orthorhombic minerals include olivine and sulfur. These minerals exhibit the characteristic orthorhombic symmetry, which can be observed in their geometric forms. The study of orthorhombic crystals helps scientists understand the properties and behaviors of various materials in nature.
