Hand modelling of compression, tension and shear in the Earth

Today's new Earthlearningidea is 'Modelling Earth stresses with your hands; hand modelling of compression, tension and shear in the Earth'. This is a class activity to help pupils to visualise and remember the types of stress in the Earth through modelling with their hands. The results of the different types of stress are seen in the deformation of a cube, shown in the diagrams above.
