Discuss why the analysis of sedimentary environments is important in the study of historical geology. Provide some
examples of how sedimentary rocks can indicate specific environments of deposition. Fill in the blank(s) with the appropriate word(s).
Sedimentary rocks preserve evidence of the surface processes responsible for deposition.
Many sedimentary rocks contain fossils that represent animals that only lived in specific
environments. Geologists use the compositions, textures, and structures of sedimentary rocks
to reconstruct these past environments, which in turn, can help predict future events. A good
example of a sedimentary structure that can be used in environmental determination is the
graded bed. These beds commonly are formed by turbidity currents in relatively deep water.
