Document Summary

Rocks become deformed when they are stressed which leads to strain. This can be visualized through taking a soda and compressing it flat with a shoe analogy. The three types of deformation are: ductile, brittle, elastic deformation. Ductile materials undergo smooth, continuous plastic deformation and do not spring back to their original shape when the deforming force is released. Take a roll of dough and drop a big ass geology textbook on top (cid:498)plastic(cid:499) deformation of it, and you get ductile deformation! There are three types of ductile deformation: folding, stretching, shearing. Brittle materials change a little and then break suddenly. Take a plate and then drop it on the floor and you get brittle deformation! There are three types of brittle deformation: reverse faulting, normal faulting, strike-slip faulting. Applies stress, deforms, takes stress away and goes back to original form.
