Answer:
Sedimentary rock
Explanation:
Coquina is a type of sedimentary rock that is comprised of shells or broken fragments of shells. These shells are made of calcite or phosphate. They are mostly found in the coastal areas, as the sediments and the shells are continuously affected by the sea waves, and are responsible for the weathering, erosion, and deposition of these sediments.
These sediments when deposits over one another over a specific period of time, give rise to the formation of this limestone rock named Coquina.
