82 Examples of the Mohs Scale Simplicable

The mohs scale is an ordering of materials according to which material can scratch which other material. This produces an informal measurement of scratch hardness that is useful to field geologists. The mohs scale isn't accurate enough to be used for most industrial and scientific purposes as more precise and comprehensive measures of hardness exist.
