Answers 2023/2024
Stratigraphy is primarily the study of sedimentary rocks - ANSWER-False
Relative dating principles like superposition are rarely applied by stratigraphers, as they rely mostly on
numerical dates. - ANSWER-False

Walther's law states that facies seen in a conformable vertical sequence will also replace one another
laterally - ANSWER-True
Marine transgression and regressions are events where sea levels change due to tectonic and climatic
events - ANSWER-True
Range zones indicate the total time a species existed in the geologic record - ANSWER-True

time in regular and determinable order. - ANSWER-False - predictable, not determinable order
Systems of rock units were established on the basis of superposition and fossil content. - ANSWER-True
, Rocks in a formation can belong to multiple lithostratigraphic units. - ANSWER-False

False

same time?
