Q: Sand stone is :
  • A. Sedimentary rock.
  • B. Metamorphic rock.
  • C. Igneous rock.
  • D. Volcanic rock
Correct Answer: Option A - Sand stone–Sand stone is a sedimentary rock and hence stratified water absorption is (5-6)%. Porosity range is (5–25)%, compressive strength is 650 kg/cm². Its specific density is 2.65 to 2.95.
