These worksheets address Ohio State 8th Grade Standard: Evidence of the dynamic changes of Earth’s surface through time is found in the geologic record. Earth is approximately 4.6 billion years old. Earth history is based on observations of the geologic record
and the understanding that processes observed at present day are similar to those that occurred in the past
(uniformitarianism). There are different methods to determine relative and absolute age of some rock layers in the geologic record. Within a sequence of undisturbed sedimentary rocks, the oldest rocks are at the bottom (superposition). The geologic record can
help identify past environmental and climate conditions.
