Use the physical principles of relative dating to interpret the
geologic history of the cross section below. List the rock
units (A-M) and geologic events (unconformities R and S and the
tilting of some units) in order from the oldest to the
youngest. Briefly explain at least two principles you used to
determine the relative age and order of events.
