    What is gravel and where is it found?  
    • A. 

      Gravel is a "bluestone" sedimentary rock that looks blue in color. Bluestone is made up of sediments that underwent millions of years of compression to become stone. It is mined in a quarry and crushed to make gravel. 

    • B. 

      Gravel is a sediment that is found at the mantel of the Earth. It is blue because it made from volcanic ash. It is found at the base of a barrier island's sand. It is mined on the barrier island.

    • C. 

      Gravel is a soil that is used in agriculture for crop growth. It is found in farm lands.

    • D. 

      Gravel is a sediment that is made up of organic material, fossil plants and animals that underwent  millions of years of compression to become stone. It is found under the maritime forest of a barrier island.
