Document Summary

Under stress, rocks can exceed the elastic limit before flowing (ductile deformation) or being fractured (brittle deformation) Brittle def. common near surface; ductile def. common at depth. Strike - compass direction of horizontal line on the planar surface of a bed or fault. Dip angle of inclination (fall line) of the surface, at a right angle to the strike. Fold: compressional force: anticline(arch, syncline (trough, monocline (step, dome (oldest rock in middle, bain (youngest rock in middle) Faults: displacement of rocks: dip-slip: along dip fault.
