The new ELI today is ‘Looking so far into the Abyss of Time’; how to visualise the immensity of geological time...with a rope!'
This Earthlearningidea is an exercise to demonstrate the extent of geological time-scales and the need for meaningful geological reference points, obtained from fossils and other geological events, recorded in the rock record.
Many related activities can be found in our Geological Time category.
This Earthlearningidea is a method of helping pupils to visualise the enormous time-spans between the upper and lower layers of unconformities.
