Investigation Followup PROCEDURE The purpose of this experiment is to test different minerals to see where on the Mohs hardness scale they would fit. My question and problem‚ “What mineral is the hardest out of all?” My hypothesis is by looking at all mine minerals‚ amethyst is the hardest mineral‚ followed by opal‚ than apatite‚ then halite‚ than graphite and the muscovite will be the softest mineral. To begin this experiment‚ I purchased and gathered all my materials

Introduction Metamorphism is defined as the mineralogical‚ chemical and structural adjustments in solid rocks to physical and chemical conditions which have been imposed due to changes in pressure and temperature or both. Metamorphism occurs below the surface zones of weathering and cementation. Conditions of metamorphism differ from the conditions under which the rocks in question were originally formed. Metamorphism produced as a result of the progressive increase in temperature and pressure‚
