Why is the hardness of a rock sometimes referred to as a scratchability?

∙ 7y ago
Sometimes the concept of hardness is confused with whether or not a mineral will break. It is important to understand that even though a diamond is extremely hard, it can shatter if given a hard enough blow in the right direction along the crystal.
Hope this helps!

∙ 7y agoThe Mohs scale is determined by what can scratch what. The softest mineral, talc, could be scratched by everything and measured 1. Nothing could scratch diamond and it was scale 10. In between was an ordered list of materials, depending on scratchability.
