Question

7. Which type of sedimentary rock (organic, clastic, or chemically/biochemically precipitated) is present in this photo?

A. Organic

B. Clastic

C. Igneous

D. Chemically/biochemically precipitated

8. Describe why the process of lithification is important in the formation of sedimentary rocks.

A. It binds sediments into a solid mass through compaction and cementation

B. It adds a lithium which chemically binds the sediments into a rock

C. Lithification does not play a part in the formation of sedimentary rocks

D. Lithification only plays a role with organic sedimentary rock formation

9. Why is contact metamorphism restricted to a small area?

A. Because the body of protruding lava which causes contact metamorphism is relatively small in size

B. Because the body of intruding magma causing contact metamorphism is relatively small in size

C. Because only certain rocks can be metamorphosed and they are generally found in small quantities

D. Because all metamorphoses are restricted to small areas
