An exercise on how to use the contact relationships and information about rock ages to reconstruct the geological history of an area. Suitable for teachers and college (A Level) students.
A sea cliff somewhere in Britain exposes a variety of rocks (A – H).
Most of the rocks have some evidence of their age as listed in the exercise.
The challenge is to list the rocks in their stratigraphical order and suggest when each was formed. With this information, write the geological history of the cliff including how each of the rocks may have formed as well as periods of earth movements and erosion.
