Properties of Granite | Physical | Thermal
Rocks are rated on the on the Moh's Hardness Scale which rates the rocks on the scale from 1 to 10. Rocks with hardness 1-3 are soft rocks from 3-6 are medium hardness rocks and 6-10 are hard rocks. The hardness of Granite is 6-7 whereas its compressive strength is 175.00 N/mm 2. Streak is the color of rock when it is crushed or powdered.
