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 Basalt is 6 whereas its compressive strength is 37.40 N/mm2. Streak is the color of rock when it is.
