Quizplus · Accepted Answer

A mineral's hardness is typically determined by its resistance to scratching or abrasion by other materials of known hardness. This is measured using the Mohs scale, which ranks minerals from 1 (softest) to 10 (hardest). The hardness of a mineral is an important characteristic that can help identify it and distinguish it from other minerals.
