  2. Create a flashcard for each of the following terms (found on p.295 in your text book). • Earthquake • Elastic rebound • Focus • Epicenter • Body wave • Surface wave • P wave • S wave • Shadow zone • Fault zone If you finish early, study your flashcards! Key Terms

  3. Quickwrite: Describe what happens when a rock is thrown into a pond. How might this be similar to an earthquake? INTERACTIVE

  4. Earthquakes are movements of the ground caused by a sudden release of energy when rocks along a fault move. Rocks on both sides of a fault are pushed tight against each other. As stress builds up on one or both sides the rocks eventually and suddenly slip past each other. This causes the shaking of an earthquake. Why earthquakes happen

  5. Elastic Rebound is the sudden return of elastically deformed rock to its undeformed shape. Elastic rebound

  6. Elastic Rebound Demo

  7. The FOCUS = the location along a fault where the earthquake occurs. EPICENTER= the point on the Earth’s surface directly above the focus. Anatomy of an Earthquake

  8. Draw and label a diagram for an earthquake… Interactive!

  9. What is the difference between the focus and the epicenter? ________________________________________________________________________ __________ ________ is the theory that rock returns to its original shape. Quick Check!!

  10. As rocks slip along the fault lines the energy released as vibrations are called SEISMIC WAVES. • Waves are like the ripples in a pond when you throw a rock in. • 2 types of waves: • Body Waves • Surface Waves Seismic Waves

  11. Body waves

  12. Seismic Waves Brainpop--Earthquakes Enjoy the music and the show

  13. Earthquakes generally occur near tectonic plate boundaries. • Convergent Oceanic Environments • Divergent Oceanic Environments • Continental Environments Where do Earthquakes occur?

  14. Fault zones are at plate boundaries Regions of numerous, closely spaced faults Faults are breaks in a body of rock (like a giant crack) Fault Zones Let’s Go Online…

  15. Earthquakes Away From Plate Boundaries Earthquakes in places such as Missouri and Arkansas,occur because of ancient fault zones deep within the Earth’s crust.

  16. Choose 6 of the 11 questions on page 300 to answer. Assessment
