One reason that color can be so variable is that the type of surface is variable It may be a crystal face or a fracture surface or a cleavage plane and the crystals may be large or small depending on the nature of the rock One of the most important diagnostic properties of a mineral is its hardness In 1812 German mineralogist Friedrich
Mohs scale of mineral hardness is named after Sir Friedrich Mohs a mineralogist who invented a scale of hardness based on the ability of one mineral to scratch another Hint these are the three rock types that can be transformed into a metamorphic rock through burial heat and pressure Igneous Rocks Igneous rocks form when molten
