Review Rocks-4

This is called Quartzite. It was once sandstone, but heat and pressure changed it by fusing the grains of sand to each other, making it much harder. What kind of rock is it?.

  1. Igneous

    No. Igneous rocks formed from magma or lava. That would have melted the sand grains. This is not an igneous rock.
  2. Sedimentary

    No. Sedimentary rocks are deposited by wind, water, ice, or gravity, and they often contain fossils. When it was sandstone it was a sedimentary rock.
  3. Metamorphic

    Yes!. This quartzite been changed by heat and pressure from a different kind of rock. It is metamorphic.
  4. Quartzite is not a rock.

    No. Quartzite is a naturally occurring solid that forms large layers in the Earth. Quartzite is a rock.
