Harðleiki
Harðleiki is an Icelandic term that translates to hardness or rigidity. In a geological context, it refers to the resistance of a rock or mineral to scratching, abrasion, or deformation. This property is often measured using scales like the Mohs scale of mineral hardness, which ranks minerals based on their ability to scratch one another. A higher number on the Mohs scale indicates a harder substance. Harðleiki is an important characteristic for identifying minerals and understanding their potential uses, such as in construction or as gemstones.
Beyond geology, the term harðleiki can also be applied metaphorically to describe the strength of character,
