  1. Primary seismic waves Are slower than secondary Are the result of shearing forces Can travel through solids, liquids and gases Causes Earth’s to roll up and down *Please have Tier 1 Out  CRCT Question

  2. New Seating Chart

  3. Congratulations Einstein’s of the Month

  4. Tier 2 Continental Drift • Make sure you EXPLAIN the words! • Lots of GREAT creative writing!

  5. Test Answers • 3 pts per multiple choice • 10 pts for essay • Always make sure that you have an introduction and conclusion for your essay! • Great job to everyone 

  6. Joke of the DayBasketball Week What do you call a pig who can play basketball? A Ball Hog

  7. Week at a Glance Today: TIER 1 DEFORMATION due Plate Tectonic Test answers, Earthquake Notes Thursday: Earthquake Extension. Tier work time Friday. TIER 2 EARTHQUAKES DUE. Tier Workday Next week: Vocab sheet Study guide Test Tier 3

  8. Unit 5: Earthquakes & Volcanoes Two week unit! Week 1: Earthquakes Week 2: Volcanoes

  9. Tiers 3 categories: Deformation, Earthquakes, and Volcanoes Your tier 3 will incorporate language arts and science! Dates • Tier 2 Earthquakes : 11/9 • Tier 1 E and V: 11/13 • Tier 3: 11/16

  10. Due next Thursday Vocabulary Sheet

  11. http://www.youtube.com/watch?v=DppbibMhAXU Part 1: Deformation

  12. Flashcards Quiz the person sitting next to you, then switch!!!

  13. Faulting vs. Folding Faulting is breaking and folding is bending Faulting is bending and folding is breaking

  14. Organizing! Organize the following phrases into the three major types of stress!Shearing, Tension, and shearing • Squeezes the rocks of the crust • Pushes in opposite direction • Pulls the rocks • Decreases volume • Increases volume • Increases density • Decreases density • Tear and twist

  15. All you need to know about Earthquakes Today: What they are and where they are found Tomorrow: seismic waves Coffee Talk

  16. What is it? • Earthquake – is the shaking a trembling that results from the sudden movement of part of the Earth’s crust.

  17. What it Looks Like • This is an example of stress, a force that acts on rock to change its volume or shape

  18. Remember…this happens because of Stress! • shearing, tension, and compression • These forces cause some rocks to become fragile and they snap • Some other rocks tend to bend slowly like road tar softened by the suns heat

  19. Stop, Drop, and Think Where would a lot of earthquakes be found? Edges of Tectonic Plates

  20. Watch it in Action! http://www.youtube.com/watch?v=cavq2HFBa-U&feature=fvsr

  21. Did you Know? • Everyday, about 8,000 earthquakes hit Earth, but most of them are too little to feel • Earthquakes will always begin in a rock beneath the surface • A lot of earthquakes begin in the lithosphere within 100 km of Earth's surface • The focus triggers an earthquake • Focus: the point beneath Earth's surface where rock that is under stress breaks

  22. Faulting & Earthquakes • Faulting causes earthquakes. • San Andreas Fault – land to the west is moving north and the land to the east is moving south

  23. Extra: Faults • The rocks on both sides of a fault can move up or down or sideways • When enough stress builds on a rock, the rock shatters, creating faults • Faults usually occur along plate boundaries, where the forces of plate motion compress, pull, or shear the crust too much so the crust smashes

  24. Extra: 2 Kinds of Faults Strike Slip Normal Tension forces in Earth's crust Normal faults are at an angle, The hanging wall slips downward Normal faults occur along the Rio Grande rift valley in New Mexico, where two pieces of Earth's crust are diverging • Shearing creates this fault • Rocks on both sides of the fault slide past each other with a little up and down motion • It becomes a transform boundary

  25. Strike-Slip

  26. Normal

  27. Tsunami’s & Earthquakes • Tsunamis – earthquakes that occur on the ocean floor produce giant sea waves called tsunamis.

  28. Parts of an Earthquake • Focus – the point beneath the Earth’s surface where the rocks break and move. • Epicenter – directly above the focus, on the Earth’s surface

  29. Tier 2 Options Option 1: Create a radio announcement for an earthquake warning Option 2: Create an advertisement for

  30. Tier 2 Earthquakes Rubric Part 1: Vocabulary (9 points each) Did you accurately communicate the following vocabulary • Focus • Epicenter • Stress (Tension, shearing, compression) • Seismic waves (P waves, s waves, surface waves) • Plate Boundaries • Faulting • Folding • Seismograph • Richter Scale • Plate tectonics Part 2: Presentation (10 points) Is your project neat, legible, creative, and organized
