  • Tectonic Plates

  • Types of Differential Stress123

  • Ductile DeformationRock will flow in response to stressRock will change shape during flowExample: Copper penny on train tracks

  • Brittle DeformationRock will break in response to stress Example: Glass objects, broken bones

  • Deforming MarbleShallow Crust BrittleDeeper Crust DuctileM.S. Patterson, Australian National University
