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. What will be an ideal response?
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 sedimentary rocks to reconstruct these past environments. 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.
