Physical properties of rocks are used to identify the type of rocks and to discover more about them. There are various physical properties of Coquina like Hardness, Grain Size, Fracture, Streak, Porosity, Luster, Strength etc which defines it. The physical properties of Coquina rock are vital in determining its Coquina Texture and Coquina Uses.
The physical properties of Coquina depend on its formation. Physical properties of rocks play an important role in determining its applications in various fields. 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 Coquina is 1-2 whereas its compressive strength is Not Available. Streak is the color of rock when it is crushed or powdered. The streak of Coquina is white whereas its fracture is irregular. Luster of Coquina is the interaction of light with the surface of Coquina. Luster of Coquina is dull to vitreous to submetallic. Coquina cleavage is not available. The specific gravity of Coquina is 1.10-2.24. Coquina is opaque in nature whereas its toughness is not available.
