c. marine

d. beach

Put the geologic features in the following cross-section in order from youngest to oldest using the principles explained above. Then use this cross-section to answer Questions 2 through 5. Note that the legend on Page 78 is the same for all rock types in this exercise. Younges -F G90 Olde

Explanation / Answer

1) YOUNGER ( E-H-N-C-J-O-G-B-D-M-A-F-I-L-K) OLDER

2) Angular unconformity -D ( angular relationship between two strata

Non-unconformity- N ( metamorphic or igneous rock overlain by sedimentary rock

disunconformity- L ( horizontal unconformity )

3) The lithology of F is limestone which is calcium carbonate and are fine grained rock which is formed under very quite environment . hence all the limestone composition rock derive thier deposition to marine environment.
