Describe this hypothesis. Stress is force imposed on rocks. Compressional - squeezing. Types of deformation Elastic, brittle, ductile, plastic. Anticline, syncline, dome, basin, fold axis, axial plane.
Rocks are strong.
Be able to determine fold type from strike and dip, or ages of exposed rocks. Be able to relate compressional, extensional, and shear stresses to normal, reverse, and strike-slip faulting.
