Paleoceanography analyzes layered sedimentary deposits to trace distinctive layers while establishing
the ages of these deposits. Indicate whether the statement is true or false.
ANS: F
The discipline of stratigraphy looks at the layers of deposits, determining their ages from the core
samples taken. Paleoceanography analyzes data to determine past ocean and atmospheric circulation
patterns. This is accomplished, in part, by looking at elements present in marine microfossils.
Information can be found in the section Sediments Are Historical Records of Ocean Processes.
