Let's consider 'What catastrophic natural processes affected your region in the geological past? Use the evidence in your local region to interpret dramatic geological events'.

In this Earthlearningidea, several photographs are used to stimulate discussion about possible rapid geological processes in the past which might have had “catastrophic” outcomes if there had been humans on the Earth at those times.
