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 1.Compression = squeezing or pushing together (convergent boundaries) 2.Tension = forces stretch an object (divergent boundaries) 3.Shearing = slicing motion back and forth (transform boundaries)

4 Types of Folding Folding: rock layers bending because of stress 1.Anticline = upward bend 2.Syncline = downward bend 3.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) Fault Line HANGING WALL 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 COMPRESSIONCOMPRESSION…mountains formed at continental/continental convergent boundaries. Ex. Appalachian Mountains COMPRESSION Appalachian Mtns.

9 Fault Block Mountains TENSIONTENSION…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 SYNCLINEANTICLINE
