Key Concept What are the three types of sedimentary rocks?
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
1. made from broken pieces called clasts
2. made from minerals that crystallize directly from water
3. begins with dissolved minerals entering the ocean
4. was formed by or contains the remains of organisms
5. Chert is most often an example of this type of rock.
6. Breccia is an example of this type of rock.
7. begins with water flowing through cracks or empty spaces on rock
8. forms from animal hard parts that compact
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.
15. Force and an erosional element determined its size and shape.
16. Rock gypsum is an example of this type of rock.
17. Its name in Greek means “broken.”
18. can be made up of large sediment pieces
