Directions: On the line before each description, write the letter of the type of rock that matches it correctly.
A. clastic rock
B. chemical rock
C. Organic / biochemical rock

9. Rock salt is an example of this type of rock.
10. becomes rounded as they are transported
11. classified by size and shape
12. starts with removing silicon and oxygen from seawater
13. Conglomerate is an example of this type of rock.
14. Coal is an example of this type of rock.
