Another Earthlearningidea using an empty box to investigate faulting. This activity models how tensional forces can cause fractures in rocks, sometimes creating rift valleys like the one in Iceland in the photo. This activity could be used to extend a physics lesson on forces or to aid understanding of surface features such as fault scarps (steep slopes along a fault plane) and rift valleys.
