  1. Science *Stack Test Corrections for collection Do Now: 12-2 HW: STUDY TODAY’S NOTES – QUIZ THURSDAY WORK ON PLATE TECTONIC PROJECT 1. LIST THE THREE TYPES OF PLATE BOUNDARIES AND SHOW THEIR MOVEMENT WITH ARROWS. Today ~ Power Point w/notes: Deformation of the Earth’s Crust

  2. Deforming the Earth’s Crust

  3. Types of Stress • Deformation: When the shape of a rock changes due to stress • Compression = squeezing or pushing together (convergent boundaries) • Tension = forces stretch an object (divergent boundaries) • Shearing = slicing motion back and forth (transform boundaries) Compression Tension Shearing

  4. Types of Folding • Folding: rock layers bending because of stress • Anticline = upward bend • Syncline = downward bend • Monocline = bend with horizontal ends

  5. Types of Faulting • Fault: the surface along which rocks break and slide past each other • Hanging wall: the layers of rock ABOVE the fault line (…above the diagonal) • Footwall: the layers of rock BELOW the fault line (…below the diagonal) HANGING WALL Fault Line FOOTWALL

  6. Hanging Wall and Footwall How can I remember which is which???

  7. Types of Faults • Normal Faults = the hanging wall slides down the foot wall • Reverse Fault = the hanging wall slides up the foot wall • Strike slip Fault = the rocks on either side of the fault line slide past each other “It’s Normal to Hang Down.”

  8. Folded Mountains • COMPRESSION…mountains formed at continental/continental convergent boundaries. • Ex. Appalachian Mountains Appalachian Mtns. COMPRESSION

  9. Fault Block Mountains • TENSION…causes large blocks of the Earth’s crust to drop down compared to the rocks around it. • Ex. Tetons (Wyoming) TENSION

  10. Volcanic Mountains • Formed at Ocean/Continental and Ocean/Ocean Convergent boundaries. • Ex. Ring of Fire Ring of Fire Mount Saint Helens

  11. You’ve seen this before!... NORMAL FAULT ANTICLINE SYNCLINE
