Laying down the principles

'Laying down the principles - sequencing the events that form rocks through applying stratigraphic principles' is our latest Earthlearningidea. The activity illustrates in a visual way most of the major principles/laws/guidelines that geoscientists use to work out the sequences of events that formed and deformed rock sequences (the relative dating of the events), and from those, the geological history of the rocks of the area. These principles have complex sounding names but they are very easy to demonstrate, understand and use as this activity shows.
Please try it out and let us have your thoughts.
