    Rock hardness is a term used in geology to denote the cohesiveness of a rock and is usually expressed as its compressive fracture strength. Terms such as hardrock and softrock are used by geologists to distinguishing between igneous/metamorphic and sedimentary rocks, respectively. These terms originated from historical mining terms, reflecting the methods needed to economically mine an ore ...
