The Mohs scale was devised by a German geologist and mineralogist Friedrich Mohs in 1812. It works by analyzing the ability of a material to scratch the other (softer) material. Although the Mohs scale is not precise and strictly ordinal, it has a relevant use in geology, mostly to identify various minerals.
