Hardness
A mineral’s resistance to scratching
Real World Example
Imagine trying to peel the sticker off a new purchase without leaving any sticky residue behind. Just as some stickers cling stubbornly while others peel off effortlessly, a mineral's resistance to scratching varies based on its hardness. In both cases, the challenge lies in overcoming resistance: the sticker's grip on its surface or a mineral's resistance to an external force. Both scenarios illustrate how certain surfaces, whether a product or a mineral, can withstand attempts to alter them based on their inherent properties.
